Geometric calculator application example. The geometry calculator is a very useful tool provided by AutoCAD R12. Like ordinary calculators, geometric calculators can complete ,, *, and / calculations and triangle functions. This allows the user to arithmetic operations with a computer in the case of uninterrupted commands using the AutoCAD drawing process, and AutoCAD uses the result of the operation as the parameter of the command. But it is important that the AUTOCAD geometry calculator can be made by the general calculator. It can make the addition and subtraction between the coordinate point and the coordinate point, you can use AutoCAD's OSNAP mode to capture the coordinate points on the screen, and automatically calculate geometric sites. If the intersection of two intersecting straight lines is calculated, the equal points such as the straight line are calculated. In addition, the AutoCAD geometry calculates the function of calculating vector and normal. Of course, the AutoCAD geometry calculator has other functions, which is not one of them. In the use of AutoCAD drawings, you often need to determine some points that cannot directly give coordinates. For example, the midpoint between two points; the circle of the circle is tangentially cut in any direction; and any other equivalents on the line. This is the positioning problem of our usual CAD drawing. In fact, in many computer drawings, whether or not the positioning is convenient and accurately directly affecting the efficiency and speed of the figure. Therefore, you should make full use of the geometric calculation function of the AutoCAD geometry calculation to realize the fast positioning in the AutoCAD drawing. In the command prompt Command: Type the auxiliary menu item that CAL or activates the drop-down menu Picking the geometric computing menu item to start the AutoCAD geometry calculator. The CAL command is also a transparent command that can start the geometric calculator at any time under other commands. In addition, you can use the CAL command in the Autolisp program.
Below is an instance of several fast positioning frequently encountered in the AutoCAD drawing using the geometric calculation function of the AutoCAD geometry. 1. Determination between the two entities This point does not need to draw a auxiliary line between the two entities and then use OSNAP's MID mode. For example, you have to draw a line from a center between a center and a straight end point. The procedure is as follows: Command: Line from Point: 'CAL (Startup Geometric Calculator) >> Expression: (CEN END) / 2 (Input Expression, here the calculator puts OSNAP CEN and END mode as a point coordinate Storage unit) >> SELECT Entity for CEN SNAP Catch Cartested with Cursor Cartridge) >> SELECT Entity for End SNAP TO POINT: Other target capture patterns such as int, ins, tan, etc. can be calculated in geometric calculations Use in the expression. If the expression (CUR CUR) / 2 replaces the expression (CEN END) / 2, you can set the OSNAP mode to capture the desired point when the computer is required to enter a point. 2. Determine any of a linear equal point and point to the linear end point to use the PLT and PLD functions provided by the geometry calculator to complete this operation. Assume that there is one end point on the screen as a straight line of A and B. The point to obtain a straight line segment AB is 1 to 2 on the straight line. Still drawing a straight line as an example, the operation procedure is as follows: Command: Line from point: 'Cal >> Expression: Plt (end, end, 1/3) >> SELECT Entity for end Snap with cursor capture endpoint a) >> SELECT Entity For End Snap Captures the end point B by the cursor to get a point where the point 1/3 line segment is the point of the 1/3 line segment) to Point: If you want to get the point of the straight line, the endpoint A is 5, use the function PLD (End, End, 5) instead PLT (End, end, 1/3) during the above operation. 3. Use the relative coordinates to determine the point in the drawing, often draw another line relative to one line, the following is the operation process: Command: line from point: 'Cal >> Expression: End [2, 3] (Point and point Equal operation) >> SELECT Entity for End SNAP to capture the endpoint of a reference straight line to obtain a point of the endpoint relative displacement (2, 3) to Point: This function is similar to the FROM target capture mode provided in AutoCAD R13. 4. Circle and a slope of a slant line and a circular cut line with a round of a rounded tangent using AutoCAD orthogonal model. Circles drawing a tangent to the slash need to accurately determine the center. The operation procedure is as follows: Command: Circle 3P / 2P / TTR /: 'CAL >> Expression: CUR 3 * Nee (Cur Indicates that the cursor picks up a point on the screen, the NEE function is used to calculate the normal line of the two end point vectors, 3 Is a radius of circle) >> Enter a point: NEA (with cursor to capture a point as a circle as a circle and straight line) TO >> SELECT One endpoint for NEE with cursor capturing a straight line) >> SELECT Another Endpoint For NEE Captures the other endpoint on the straight line) DIAMETER /: 3 (which can draw this round) to change the order of the two endpoints of the optical label capture cables can be drawn on the other side of the straight line.
It is assumed that the operation of the round and a straight line is as follows: Command: line from point: int (capture points) of to points: 'Cal >> Expression: int 3 * Nor (cen, int) >> Select Entity For int SNAP Capture Care Point) >> SELECT Entity for Cen Snap with Cursor Catch Carten) >> SELECT Entity for int SNAP re-uses the cursor to capture the intersection point, which is a known circle from the intersection of 3. TO POINT: 5. The vertical line of a known point on a slash is the vertical line of the orthogonal model of AutoCAD cannot be drawn by the non-vertical straight line. The geometry can be directly drawn and the slash is perpendicular and the straight line of the determined length. In fact, this is a problem with another endpoint of the vertical line. The procedure is as follows: Command: Line from Point: MID (set the midpoint of the line) of to points: 'Cal >> Expression: MID 5 * Nee (5 is the length of the vertical line) >> SELECT Entity For MID Snap Selecting the Cursor Select Oversed Wire Capture) >> SELECT One Endpoint for Nee Use the endpoint of the cursor to capture the straight line) >> SELECT ANOTHER EndPoint for Nee Use the other endpoint of the straight line to capture the straight line) TO POINT: Similarly, change the cursor capture The order of the linear endpoint can also be drawn on the other side of the straight line. When you open the other person map, how to do the font that can't be found? Very good way! I hope to fix! When you open someone, you should keep replace the font file, how can you once? A: There are two ways. 1: Copy the flyworthy to replace to be replaced with the font name, such as, open a picture, prompt to find the JD font, you want to replace it with Hztxt.shx, then you can put hztxt . SHX replicates one copy, named JD.SHX, you can solve it. However, the disadvantage of this approach is obvious, too occupying the disk space. It is best to use the following way.
2: Create an acad.fmp file in the AutoCAD R14 / Support directory, if this file is turned on directly, this is an ASCII file, enter "JD; hztxt", if there is another font to replace, you can row, Such as "jh; hztxt", the deployment exits, later if you open the figure contains JD and JH, you don't have a font in your machine, you will never stop if you look for a word library. Solving AutoCAD Method for fatal errors when printing under XP operating systems Recently, some members reflect AutoCAD 2002 or 2004 versions of the event of fatal errors when clicking printing and exiting AutoCAD. After my study, this is related to the print stamp with AutoCAD 2002 and above. When 2000, the added print stamp function has a lot of bugs. This feature is directly used as AutoCAD functionality after 2002. This feature is completely no problem in the 98 operating system, but it will be wrong in some XP systems. Therefore, it is best not to open this feature in the XP system. If you have unfortunately open this feature and make AutoCAD a fatal error when printing, the solution can only be like this: find the acpltstamp.arx file in the root of AutoCAD, change it to other names or delete. This will not be wrong again, but there are also less print stamps. This method is effective for the 2002 version and 2004. Author: Xu Cheng Yuan "↑", "↓" We all know that the use of keys on DOS, the role of the down arrow key, and if you can remember running DOSKEY each command you type, use the same command again Don't need to knock again, use it, down the arrow key to choose. Also available in AutoCAD, the down arrow keys Select the previously typed command. This is most useful when entering text, whether it is a text or dtext command, can use the input text when entering text, down arrow keys to reduce the input of the command. Of course, the number of rows recorded by AutoCAD is limited, but can be set to increase its record amount, the step is to select [Tools] → [Preferences ... (parameter selection)] → [Display]] In the [Text Window Parameters] box, the second line "Number of Line of Text In Text Windows to Keep In Memory" (the number of words that retain the text window in memory) is the line of settings. Number, the larger the value, the more records, but if the machine is stored, it is still some of them to avoid accidents, and its value is between 25 and 2048, the machine is 128M memory, has been This value is set to 2048, and there is no mistake, you can try a few times according to your computer, find a suitable value. In order to select the commands, you should minimize the input repeated and meaningless commands from the keyboard when using AutoCAD, such as the transfer of the layer dialog and the use of the undo command, you can call the menu to call the menu "!"! " Key use
"!" Also useful? Yes, let me tell the usage example to introduce it.
Suppose there is a known length line on the screen (refers to a single line, a polynomless line, the unknown length can also be), and there is a certain angle with the horizontal direction, and it is required to shorten the length of a certain length and the direction is not changed. I think each CAD users will have their own methods (you won't want to rotate the coordinate system?), But I don't want to use the commands, and use "!" As auxiliary command, use a command, the operation process is as follows :
In the "Command:", the line is selected directly, so that the clip occurs, move the cursor to one end to shorten and activate the clip, so that the line becomes a stretched rubber band, put the cursor The direction of the line moves, so that the bib line and the original line segment are complicated, the distance between the movement is not limited, and some people think that the direction of movement cannot use the auxiliary point to capture the command. After the screen prompt, enter "NEAR" and press the space bar, this There will be a prompt on the screen to capture some point on the original line segment. At this time, enter "! Xx" after the prompt "! Xx" (XX is a specific value), the length of the line changes. How! If you don't believe it, you will use the list command before and after this command to see the length of this line segment. Find a font
The most annoying man with autocad is the most discovered picture that does not find the corresponding font in this unit, there is a variety of garbled, causing the reason for can't find the font, the font storage location and yourself The location of the machine is different. The general solution is to redefine, but sometimes this approach is not always valid, and it may also cause unexpected errors to make AutoCAD crash, more likely to cause graphic files. I used another autocad command to reach two destinations in an accidental opportunity, that is, using a repair (Recover) command. First run AutoCAD, select the "Recover" command in the File menu, select the graphics you want to process, fix, the dialog box requesting the font is required during the repair process, you can click the correct font file to redefine, After the repair is completed, the text can be displayed normally. One thing I want to remind everyone, if the Chinese used in the graphic file is the non-GB-coded font file, you have the corresponding font file to display text.
Optimize the AutoCAD system
First, optimize the Windows system 1. Clean up maintenance disk, optimize Windows system performance If AutoCAD fails, it may cause non-normal to exit the exchange file and lose some disk clusters. The Windows system automatically checks the missing disk cluster at startup. If you don't want to restart your system, you can run Chkdsk from the command line. 2. Solving disk fragments, optimize Windows system performance What is disk fragmentation? The individual parts of the same disk file is dispersed in different regions of the disk, and the fragmentation will be generated when the old file is deleted in the disk. It slows down the access speed of the disk and reduces the comprehensive performance of the disk. Just as a novel is not printing on a continuous page, but a "Go to XXX Page" needs to occur every few lines. AutoCAD is running, you need to create a certain temporary file in the disk, and if distributed among the disk fragments, naturally reduce the speed. Run the "Disk Defragmentation" to organize disk fragmentation? Second, optimize the AutoCAD system 1. Optimize the two-dimensional multi-segment lines created by AutoCAD R13 or earlier versions from the R14 version, AutoCAD creates a two-dimensional multi-segment and associated fill in an optimized format, which saves memory and disk space. Use the Convert command to update the fill pattern or multi-step line created by AutoCAD R13 and its earlier versions. 2. Delete Named objects in the graphical database, effectively reduce the graphic file size over time, some useless naming objects may accumulate (not in the object). For example, graphic text is no longer used, or the layer of any graphic object is not included; more even, containing huge unused pieces. Cleaning operation only deletes a hierarchical reference. It may be necessary to repeatedly perform the cleaning operation three times. Note If the drawing is cleaned, the cleaning waste may be cleaned off the defined drawing template. 3. The group will seriously affect the speed of selecting class operation, and should delete the group is the named object selection set, different from the unnamed selection set, and the group is saved with the graphic. The group is a naming object, but unfortunately you can't use the purge command to clear. If an object is deleted or remove it from the group, the group remains originally defined. If there is a large number of empty groups, it will seriously affect the selection speed. 4. Online Optimization AutoCAD is installed on the web server or on the client workstation, the user can share the data on the server hard disk and store unwanted shared graphics on the local hard drive. The two methods have their advantages. Install AutoCAD on the client workstation to optimize network performance. Installing AutoCAD on the server allows users to share an executable, saving disk space and makes software installation and upgrading. You can also set up the client installation and the server on the server installation and the server according to your own network configuration. 5. Performance to load and optimize external references By combining graphics to load and save the index, the performance of the external reference can be improved. When you load the on-demand, if the index has been saved to the reference graphics, AutoCAD will only load data related to the regenerative current graphic from the reference graph to memory. In other words, the referenced material is read as needed. Excellent performance on demand is: (1) Trip the external reference to display a small portion of it, and the space index has been saved in the external reference pattern; (2) freezing the external references, and the layer index Save together with external reference graphics. 6. Load other geometric graphics to local open graphics If a large graphics can be processed, you can use the Local Open option to select the objects you want to process in the graph and objects in the layer (graphic objects only). Once the graph is locally opened, you can use the Partiaload command to load other geometric graphs from the view, selected area, or layer in the graphics.
7. Other operational techniques (1) Freeze or close the layer freezing layer When AutoCAD does not refresh the object database on the frozen layer, thereby increasing the speed. When closing the layer, it is convenient to operate without regenerating. (2) Closing the complexity of the visible element graphic affects the speed of the AutoCAD refresh screen or handling the command. If you need to improve the performance of the program, you can close the text, line width, fill, and select the content and point tag. (3) Changing the temporary exchange file location Windows TEMP directory is the default location of the temporary exchange file. You can find the "Temperature Graphics File Location" in the File tab of the Options dialog, you can specify a different directory by adding the record item. (4) Manage grating images, such as temporarily uninstalling images, detachable images no longer needed in the graph, control image display quality. (5) Temporary uninstalling external reference. (6) Replace the TTF font using the SHX font. (7) Control the appropriate display performance. ☆ Use virtual screens to reduce rebuild. ☆ Display accuracy. You can use viewres commands and FaceTRES system variables to control circles, arcs, and elliptical display accuracy. ☆ It is forbidden with raster image translation and zoom. System variable RTDISPLAY = 1. ☆ Only bright grating image borders. ImageHLT = 0. ☆ Close the entity fill. FillMode = 0. (8) Adding RAM is the most effective way to improve system performance. Installing more RAM can reduce AutoCAD to use temporary exchange and page scheduling requirements to achieve optimization performance. (9) If the memory is small, the permanent exchange file is used, and the speed is faster than the temporary exchange file. The hard disk reserves a certain amount of space for system buffering. (10) For a large three-dimensional map, forced AutoCAD to view the objects of the model space as two-dimensional objects can be more effectively utilized. Related system variables are TreeMax and Treedepth. Third, expansion software, rich expertise (1) adopts a professional software based on the AutoCAD platform. AutoCAD can draw any complex graphics, but Autodesk never recommends the user to draw a top drawing with the most basic command. (2) Use genuine software to support the development of CAD career, and new products will will enhance your company's productivity. (3) Do a good job in the system planning within the workgroup or the company to make full use of the advantages of user customization. (4) Participate in Autodesk certification training, improve the capacity of CAD design team. Author: Zhang Bin Full
Ways and techniques for improving drawing efficiency using AutoCAD 2000
First, follow the principle of a certain amount of mapping In order to improve the speed, the user is best to follow the following mapping principles: 1. Fragraph Procedure: Set the Mount → Setting Unit and Accuracy → Create Several Layers → Setting Object Style → Start the drawing. 2. The drawing is always used in 1: 1 ratio. To change the size of the pattern, different print ratios can be set in the drawing space during printing. 3. Set different layers, colors, and wire width for different types of primitives, while the color, linear and line width of the primitive, linear and line width should be controlled by layer. 4. When you need to accurately draw, you can use the raster capture function and set the grid capture between spacing to the appropriate value. 5. Do not paint the box and graphics in the same picture, you should insert the box in the layout (Layout), then print out. 6. For famous objects, such as views, layers, tiles, line types, text styles, print styles, etc., not only makes concise, but also to follow certain laws to find and use. 7. Set some common settings, such as layer, labeling style, text style, grid capture, etc., in a graphic template file (ie, saved as a * .dwf file), you can draw a new graphic wizard when drawing new graphs later. Click "Use Template" to open it and start drawing. Second, use the appropriate command user to control AutoCAD, is achieved by issuing a series of commands to it. When AutoCAD is connected to the command, the command will immediately execute the command and complete its corresponding function. During the specific operation, although there can be a variety of ways to achieve the same purpose, if the command is selected, the operation steps will be significantly reduced to improve the drawing efficiency. Taken only a few more than a typical case. 1. Generate linear or line segments (1) In AutoCAD, use line, xline, ray, pline, and mline commands can generate straight or line segments, but only the frequency of the line command is the highest, and most flexible. (2) In order to ensure the correspondence between the "long pair of positive, width, etc." between the object three view, and the XLINE and RAY command should be used to draw several auxiliary lines, and then use the TRIM to cut off the extra part. (3) To quickly generate a closed fill boundary, or want to construct a face, you should use the PLINE command. The line segment generated by PLINE can be edited with the PEDIT command. (4) When a plurality of line segments parallel to each other are generated at a time, and each line segment may select the mLine command when using different colors and line types. 2. Note Text (1) When using a text annotation, if the text in the comment has the same format, the comments are short, then the text (DTEXT) command is selected. (2) When writing a large number of words, and the text in the paragraph may have different formats, such as font, word high, color, dedicated symbol, molecular formula, etc., the mText command should be used. 3. Copy graphics or feature (1) In the same graphics file, if you copy the graphics only once, you should use the COPY command.
(2) In the same graphical file, copy a graphic copying multiple times, then select the multiple option of the copy command; or use CopyClip (normal replication) or copybase (replication after specifying the base point) command will need graphics Copy to the clipboard, then use the Pasteclip (Normal Paste) or Pasteblock (splicing in a block) command to spike the location specified. (3) In the same graphics file, if the replication graphics are arranged in a certain regular, such as a number of rows, or evenly distributed along a circumference (arc), the array command should be selected. (4) In the same graphical file, a number of lines that are parallel, intervals equal or unequal, or generate a series of concentric ellipses (arcs), circle (arc), etc., should be used to use Offset commands. (5) In the same graphics file, if the number of copies is quite large, in order to reduce the size of the file, or to make a unified modification, the specified graphic should be defined as a block with the block, and then use the INSERT or MINSERT command to block the block. Insert. (6) Two ways can be used between multiple graphics documents. First, use the command to operate. First copy the graphic to the clipboard in the open source file, and then use the Pasteclip, Pasteblock or Pasteorig three in the open destination file to the specified location. This is equivalent to selecting the appropriate options in the shortcut menu. Second, drag the picture directly with the mouse. Note: Drag and drop in the same graphics file can only be a mobile graph, and dragging between two graphics documents is a copy graphic. When dragging, the mouse pointer must refer to the pattern of the selected graphic rather than in the clip of the drawing. At the same time, it should be noted that it is different from the left mock button to drag and drop with the right click. Use the left button to drag the drag, and use the right-click to drag and drop, a shortcut menu will pop up according to the options provided by the menu. (7) Copy the graphical feature between multiple graphics documents, should be used with matchprop commands (need to match the PaintProp command). Third, using express tools (Express Tools) so-called express tools, actually designed and supplied freely with AutoCAD 2000. Most of the library comes from the Bonus tool of AutoCAD R14, and the rest have been abandoned or improved, and some new tools have been added. Express trolley tools extends the AutoCAD in many aspects of the input / output of the layer management, object selection, and size labeling, graphical editing modification, and it is very easy to combine in the AutoCAD 2000 menu and toolbar, use Convenient and fast, it can significantly improve your work efficiency. Installing the express tool is to select "Full" installation when installing AutoCAD 2000, or selects the User installation with the Express Tools option. If this is not the case, the AutoCAD 2000 should be reinstalled in the "increase", and "Express Tool" you need to add. Upon default, AutoCAD 2000 does not load the fast train when starting to shorten its startup time. When you first use express tools, the tool library will be loaded automatically.
However, you can also use the Express tools command to enhance it with Express Tools command at the beginning. If the Express menu has not appeared correctly on the screen, you can display the menu using the Express Menu command. The following is a method step of displaying the "Express" toolbar on the screen: (1) In the drop-down menu, select the View> Toolbar ..., the Toolbar dialog box appears. (2) Select "Express" in the drop-down combo box named "Menu Group". (3) Point the option you need in the combo box named "Tools". Where the crown is "X", it will display its toolbar on the screen. (4) Click the "Close" button to exit the dialog box. Fourth, the complexity of opening or closing some visual elements graphics affects the speed of AutoCAD executes commands and refresh screens. Open or close some visual elements (such as padding, wide line, text, label point, bright selection, etc.) to enhance AutoCAD performance. (1) If the Fill is set to OFF, turn off the entity fill mode, the newly painted traces, a polynoma of the width, fill a polygon, etc., only one contour will be displayed, which is not output when printing. The fill mode can be displayed using the regene command using the rege command. In addition, the system variable FillMode except controls the filling mode, and whether all the shadow lines are displayed or not. (2) Turn off the wide line display. The wide line increases the width of the line. The wide line is output at the actual value when printing, but in the model space is displayed in pixel ratio. When using an AutoCAD drawing, you can select the Wide Line option by the LWT button on the status bar, or from the Format menu, use the Wide Line Settings dialog box to turn off the wide line to optimize its display performance. The system variable LWDISPLAY also controls the wide line display in the current graph. (3) If setting QText to ON, open the fast display text mode. In this way, the newly added text in the pattern will be hidden to display only one border, and the same is true when the printout is output. This setting can be displayed using the Regen command with the Regen command. In addition, the system variable QTextMode also controls whether text is displayed. This is obvious that the impact on system performance is obvious when the text in the pattern is much more. (4) Disable the display sign point. The so-called labeling is some temporary tags that appear in the AutoCAD plot area when selecting a graphic object or positioning. They can be used as a reference point, can be cleared with the RedRaw or Regen command, but does not appear on the drawing when printing output. To disable the sign point display, you can set the BlipMode to OFF to enhance the performance of AutoCAD. (5) Cancel the brightness. By default, AutoCAD uses "highlight" to represent the currently selected graphics. However, the value of the system variable highlight is changed from 1 to 0, and the performance of AutoCAD can also be enhanced when the selection is canceled. (6) By the way, the value of the system variable regenmode is set to 0, or RegenAuto is set to OFF, saving the time of automatic regeneration of graphics. 5. Timely cleaning graphics in a graphic file may have some unused layers, tiles, text style, dimensional labels, line types, and other useless objects. These useless objects not only increase the size of the file, but also reduce the performance of AutoCAD. Users should clean up using the purge command in time.
Since the graphic objects often appear nested, it is often necessary to use a user to use a few Purge command to clean the useless object clean. 6. Use the command alias and acceleration keys AutoCAD to define alias and acceleration keys for some commonly used commands or menu items. Use the command alias and acceleration keys to significantly save the time of access commands. The command alias is defined in the acad.pgp file. Use any text editor to open and edit the file, you can add, delete, or change the command alias. Use this method to define an alias when re-enter AutoCAD. In the latest software version, users do not have to exit AutoCAD to redefine the command alias using the expressway, but if this method is used, you need to execute the reinit command to reinitialize the software before the first time you use the newly defined alias. Command Acceleration keys are defined in the acad.mp file. To add, delete or change the command accelerator key, the user can only edit the Acad.MNU file with the text editor. Modified * .mnu file must be loaded with the menu command and compile, the newly defined command accelerator can be used. I. AutoCAD form makes AutoCAD despite the powerful graphics, but the table handling function is relatively weak, and in actual work, it is often necessary to make various forms in AutoCAD, such as engineering number, how to efficiently produce form, is a Very practical problem. Draw your form with a manual line method in the AutoCAD environment, then fill in the text in the table, not only low efficiency, but it is difficult to accurately control the writing position of the text, and the text typography is also a problem. Although AutoCAD supports object links and embedding, you can insert a Word or Excel form, but on the one hand, it is not very convenient. A little modification has to enter Word or Excel. After the modification is complete, it is returned to AutoCAD, on the other hand, Some special symbols such as one-stage steel symbols and secondary steel symbols, it is difficult to enter in Word or Excel, then there is no way to have a good way. After exploring, it can be better solved: first in Excel, copy it. The clipboard, then select the Paste Special in the Edit menu in the AutoCAD environment, select AutoCAD Entities, after confirming, the form is converted into an AutoCAD entity, exploding with EXPLODE, you can edit the lines and square characters, which is very convenient.
Second, inserting the AutoCAD graphics Word documentation in the Word document, there is often a variety of illustrations, the Word drawing is limited, especially complex graphics, which is more obvious, AutoCAD is professional drawing software, powerful, very suitable for drawing complicated Graphics, plotted with AutoCAD, then inserting the Word production composite document is a good way to solve the problem, you can use the export function provided by AutoCAD to output the AutoCAD graphics first in BMP or WMF, then insert a Word document, you can first AutoCAD graphics copy to the clipboard and paste it in the Word document. It should be noted that because the autocad default background color is black, and the word background color is white, it should first change the autocad graphic background color to white. In addition, after the AutoCAD graph is inserted into the Word document, it is often too large, the effect is not ideal. Use the cropping function on the Word picture toolbar to trimming, and the empty problem can be resolved.
Third, the line width modification AutoCAD provides a polycycle line wide modification command PEDIT to make a modification of a multi-line line width (if it is not a multi-ray line, the command will be converted to a polynonym, and then change its line width ), But PEDIT operation, only one entity operation can be selected each time, the efficiency is low. AutoCAD R14 The Bonus provides the mPedit command for a batch modification of the multi-sense line width, which is very convenient and efficient. In AutoCAD2000, you can also modify the line width to the entity specified linewide property. Simply select the entity (entity set) to change the line wide, change the line wide attribute, and the line width modification is more convenient, pay attention to The LineWeight property line wideswide on the screen display or not determined in the system variable LWDisplay, which is ON, then display the lineWeight property line width on the screen, which is OFF, no display. Both the polysemous line width can control the solid line width, the difference between the two is that the LineWeight line width is absolutely line wide, and the polynomous line width is a relative line width, that is, regardless of the graphic Print, the LineWeight line width does not change, and the polynomous line width changes with the print size ratio size, the command scale has no effect on the LineWeight line, regardless of how many times the entity is scaled, and the lineWeight line width does not change, and more The width of the righteous line is changed as the scaled ratio changes. Fourth, the printing skills of graphics are not installed in the printer or want to use someone else's high-end printer to enter the autocad graphic, but other computers may not be installed, but other computers may not be installed, or because of various reasons (such as AutoCAD graphics The font display on other computers is not normal. It is not possible to make normal printing through network printing, online printing is not normal. At this time, you can print the AutoCAD graphic to the file on your computer, then form the printer file, then , Then use DOS copy command to use DOS to output the printer file to the printer, the method is: Copy
5. If you choose a skill, users can select the target with the mouse one by one, and the selected target is added one by one to the selection set. In addition, AutoCAD also provides Window (to type "W" response Select Object: or directly on the screen to the left Pull a rectangular box response Select Object: prompt), Crossing (to type "C" response Select Object: or directly pull a rectangular box from left to right on the side Response Select Object: prompt), CPOLYGON (to type "CP" response Select Object :), WPOLYGON (Type "WP" Response Select Object :) and other window mode selection target, where Window and Crossing are used for rectangular windows, while WPOLYGON and CPOLYGON are used for polygon windows, in Window and WPOLYGON mode, Only when all parts of the entity are included in the window, the entity is selected, and in the Crossing and CPOLYGON mode, the entity is selected as long as part of the entity is included in the window. AutoCAD also provides the fence mode (in response to the "F" response Select Object :) Select the entity, draw a unacceptable fold line, all the entities that intersect the fold lines are selected. When selecting a target, sometimes you don't carefully select the target that is not selected. At this time, the user can type R to respond to the "SELECT OBJECTS:" prompt, then remove some of the error from the selection, then type A, select again Centralize the target. When the selected entity and other entities are close to the CTRL key, then continue to click the left mouse button, then the entity close to the entity is displayed in turn, until the selected entity high brightness display, Press the ENTER key (or right click), that is, the entity is selected. There is also a conditional selection entity, that is, using the 'filter response Select Objects :, in AutoCAD2000, the QuickSelect method is also available to select the entity, function and filter, but the operation is simpler, convenient. The construction of the selection set provided by AutoCAD is very functional, and it is flexible to use the efficiency of the mapping. 6. Quality attributes query AutoCAD provides Point Coordinate (ID), Distance, Area (Area) query, which brings great convenience to graphics, but in actual work, sometimes you must query entity quality properties Features, AutoCAD provides physical quality attribute queries, which can easily query the inertial moment, surface torque, entity quality of the entity, etc., should be noted that the closure area of the curve, a polynomous line structure should be used first. The closing area is dominated, then execute the quality attribute query, and attributes such as the inertial moment, the corners of the entity, and the quality of the entity can be queried.
Easily delete the stubborn layer (R0R) several major professional CAD sites can often be seen in the CAD website: delete unused layers when processing the pattern, although all graphics in this layer are deleted You are deleting that you can't delete the layer. It is also true that all deletions and related tools are also. This situation will most encountered when dealing with other patterns, sometimes it can only be launched, unless the third-party tool software is adopted, otherwise, in addition to helplessness. During an inadvertent operation, I accidentally discovered a very effective way, trials were tried, and I was happy. I was happy to make it out of sharing: Open a CAD file, leaving only you need on the map. Visible graphics; point file - saved as, determine file name, in the file type column Selection * .dxf format, point the tool - option -dxf option in the pop-up dialog window, then hook at the selection object, click OK, then save You can choose to save the object; you can determine the saved file with the graphics you want to use. After completion, you will find this just saved file, and then open it. You will find that you don't want the layer, Haha, cool! This is actually a selective saving command in a DXF format, but it is a bit deep, rarely used this command, because the work needs I often use this command, and I have been treated as an alternative usage of stubborn layers, It may even be used by the software's production company, please learn to learn, there is no deleted layer under this method, of course, 0 layers except. 2000, 2002, 2004 is used, R14 has not been used, and it is estimated that this function is also available. If there is an entity in the layer to be deleted, you must first remove the entity, turn off the layer you want to delete first. 2 There is also a method to mention it in the VBA section. (Provided by MCCAD) You can select a graphic, then select File Menu -> Output-> Block file, such block files are the graphics selected, if these layers are not specified, these layers are not saved New tunnel graphics.
3 Close the useless layer, all, COPY paste it into a new file, and those useless layers will not be passed. If the block is defined in this unnecessary layer, this block is inserted in another layer, then this unnecessary layer cannot be deleted with this method (provided by Hellmen)
4 Use the layer to be very simple and very convenient to solve this problem, convert all the layers that are different from your habits to your layer, this way to eliminate the unused layer has a good thing is You just edit in your file, don't convert file formats at all, copy paste into a new file. Finally, use the purge command to eliminate the use of the unwritten block, layer, linear, etc., a refreshing picture appears in front of you, (file size can be reduced to the original 30 ~ 50% 哟 ~) (Provided by the years of no body)

Open AutoCAD2000 Chinese version (Note: Some font effects AutoCADR14 cannot be completed and do settings. Here the graphical boundary is 42000 × 29700mm, the font is 2000mm, you can set your own habits, and others are not coming.
--- First case: hollow word ---
Let us first do the most basic effect.
Steps:
]
Note: The font should choose a width of the stroke, and the Chinese and English can, single-wire body (such as txt.shx, gbenor.shx, gbcbig.shx, etc.) has no effect (Who said?).
Note: In AutoCAD, text belongs to a special type of special object, and it must be decomposed into the wiring to make more processing. "TXTEXP" is the command in the Express toolset ("Shortcut" on the AutoCAD2000 Chinese version menu bar. You must all or custom installation when installing), the functionality of this command is to make a text to constitute it Straight lines and arcs. Note that don't use the "Explode" command.
3, type "Trim" command, select "hollow word", cut off excess lines inside each text stroke.
4. Type "Boundary" command, confirm that "Object Type" under "Advanced" tab is "Polyline" option for "Pickup Point" button, click on the "Pickup Point" button, click on each stroke, enter Enter . Note: Because the strip, the stroke has become many independent zero lines and arcs, so use this command to connect each stroke into a closed polyline. Note that the result of this command is actually copied in place, and the color becomes layer color. The original object can be deleted to avoid affecting the operation. In addition, for hollow words, this step can also be not done (do nothing, the same), here is prepared for the processing of some of some of the word effect.
5, select "Background" on the screen, press "Ctrl 1", open the Object Feature dialog box, in the Color bar, select a color, or click the drop-down arrow on the right. Choose "Other", there are more colors available here.
Note: The following production is no longer in addition to color, you can change the color itself.
Ok, is it very simple to make a hollow word?
(The following additional explanation process is performed).
--- Second: Stroke word ---
Steps:
Enter a integer value for easy operation.
]
Note: The line width value should not be too large, otherwise the spin spacing is small, and the print will be blurred.
In addition, if you type the "S" (Sprig Curve) option, you can make "curve word". Look at the effect, is it very unexpected? Note Check that the original object is deleted after executing the "Boundary" command, otherwise there is a reversal distortion.
3, type the "MOVE" command, select the copy of the copy, enter the value recorded in the first step, move it to the original.
--- Third example: Frame word ---
Steps:
, Before the command.
Frame.
Note: For some words, the internal stroke does not have to be offset, such as the "national" word, only "mouth" is, which is different from the "stroke word".
3. Type the "Trim" command, cut off the extra part by one, only the outer contour of each word.
Note: There are many Chinese characters. There are too many places where the offset is repeated. If you don't pay attention, you will trim your error, so you can take the method of edge offset trim. After the trim, use the "boundary" command to create a boundary, you can make multiple offsets, thereby producing multi-layered contour effects. 4, finally type "Move" command, enter the value recorded in the first step, move the "outer frame" just copied on one side to the original position.
--- Final: Straight word ---
Steps:
1, enter "stretch word", the font is a black body.
Two, type the "Stretch" command, select the upper or lower half of the respective text, and draw up or down.
Note: If you have a grasp, you can use the "MSTRETCH" command to complete at once. Sometimes, you also need to draw a stroke to create a more exaggerated effect.
3, type "Solid" command, and fill all the strokes of the text one by one, complete.
Note: It is best to be filled with a stroke with arcs to maintain the original appearance. Also, if the "pattern fill" command will be used in the following, it will be more provincial.
In AutoCAD, the fat can be modified in two ways, first, enter text with "DText" command, then modify "Width" in the Object Feature dialog, or "Textfit" "The (text adjustment) command adjusts on the screen, which is only valid for dynamic text. Second, adjust the "Width Proportion" in the Word Style dialog. It should be said that this is not a scales of stretching words, which is only a description for everyone.
--- Article 5: Stereo ---
Steps:
1, enter "three-dimensional words", the font is amber body, and copy a copy after the decomposition text.
2, type "EXTRUED" command, select "Stereo", prompt "Tensile height" input "-300".
] If the positive value is input, it should be the same height along the Z axis, and the result is the same.
. "
4, execute this command again, press "two points" from top to bottom, and the angle is still input 30.
5. Use the same method to rotate the "three-dimensional" on one side in the same angle twice.
6. Type the "Move" command, move the "three-dimensional word" after the rotation can be aligned.
The three-dimensional words are doing this, is it a bit of the door? So don't be twisted, I have tried a number of ways and didn't take the word. I don't know which friend has a trick.
--- Sixth Case: Netbook ---
Since the font is broken down into a straight line and arc, you can use the "Pattern Fill" command. Let's use this command to make a few font effects, first do the grid word.
Steps:
1. Enter "grid" and the font is amber. Note: It is recommended to choose a brightened font, which is prone to the effect.
, Select the pattern name "ANSI37", "OK", return, enter the appropriate value in the "proportion", click the "Pick Point" button, click on the inside of the stroke, and enter "OK".
Note: If the padding pattern is too dense, or refuse to fill, adjust it with the "Hatchedit" command until the ratio is appropriate.
3. Type the "ERASE" command, delete the stroke box, and the grid is done.
Note: The AutoCAD2000 provides more patterns with respect to the previous version, and choose other patterns to produce the following font effect:
"Line Word": Select the pattern "ANSI31" under the "ANSI" tab.
"Honeycomb": Select the pattern "Honey" under the "other predefined" tab.
"Weaving word": Select the pattern "Earth" under the "other predefined" tab.
"Brick Word": Select the pattern "ar-brastd" under the "other predefined" tab.
Try another picture to see?
--- Seventh: Scenery word ---
In this example, we will comprehensively use the "outer frame" and "grid" production method to create the effect of "underwriting words".
Steps:
1, press the "outer frame word" production method, text input "underwriting word", font is a poster, offset distance 300, and copy a copy before decomposition text.
Note: It is best to increase the spacing in the "multi-line text editor" to avoid overlapping each other.
"Label, select the pattern name" ANSI38 "," OK ", return, enter the appropriate value in" Proportion ", click" Pick Point "button, click on the outer frame of each word (not point not to point In the stroke), enter "OK" in the Enter.
Note: Since it is a shading, the pattern can be arbitrarily selected, as long as it is not "Solid".
3, type the "Move" command, move the "underwent" just copied on one side to the original position align, or slightly offset.
4. Type the "ERASE" command to delete the outline.
Note: If the text is covered by shading, the text can be placed above the top of the "Draworder" command. Note that this command is often used in the operation of overlapping objects.
According to this example, it can also make the effect of "digging", as long as the "ERASE" command is used, all delete the stroke and the outline, keep the original text in the position, only the pattern part can be left The pattern is optional.
--- 第 第 八: Fill words ---
From the previous production, we will naturally think that can be able to fill the inside of the text in image files? The answer is yes, this requires a powerful command that "super pattern fill".
Steps:
1, enter "filling words", the font is amber body.
] Image of a flower, click "Open", "Image Dialog", confirm that the "Insert Point" and "Proportion" are "specified on the screen", then click "OK", then press twice on the screen Key to pull the selected image, "Accept the position of the image", enter, prompt "Developing Options", and then carriage return accepted the default "internal point", click on the inside of the stroke, click on the flowers. It was filled in the stroke.
Ok, isn't it a little bit of a CorelDRAW container effect? Delete the text stroke line and is also a good effect.
This part of the image enables the part to cover the entire text, so the part of the text pen is reserved, and the part other than the stroke will be cropped. If the image is less than the text, the image is filled with a tile, you can use the "TFRAMES" command to hide the frame line between the tile image, or Keep them, creating another effect is not available. But don't let the image are small, on the machine of my PII400, 128MB memory, ... I almost think that this effect does not do it (stupid)?
About the production of fill words, there are many variations, such as filled each stroke, which will get a colorful text effect. For images of a gradient color, you can make "gradient". Or use the image of wood grain, marble, can also produce "wood graphics" and "marble words" and so on. In short, any image is used, and it will eventually reflect the image of the fill image, color, texture, etc., you will feel that "super pattern fill) command is indeed powerful, name is not intriguing.
--- Ninth example: word in the word ---
In the above example, I appreciated the power of "super pattern fills). Below we continue to use this command to make the effect of the word word, further deepen its understanding.
Steps:
]
钮The word "in the box" is selected, return to the "Block Definition" dialog, click "OK".
Note: Directly use the non-decomposed text production block is also possible, but the performance requirements of the machine are higher, if you can endure.
3, type "super pattern fill) command, open the" Super Pattern Fill "dialog, click the" Block "button, and the block that appears in the" Super Pattern Fill-Insert "dialog box appears. Name, click "OK", click a little in the screen, then do no matter how the "Specify Options ...:", when you appear, "Specify Options ...:", click on each stroke inside, and the carriage return is completed. Note: After the above operation, the text is filled in the form of tiles and is trimmed at the edge of the stroke, but is still a block.
--- Tenth: Shadow word ---
The above special effects are made on the basis of decomposition text. Here we see what effect can be created without breaking the text. The shadow word is a most basic text effect, we will take it.
Steps:
]
]
3. Execute "Copy" command again, copy the "shadow word" to the lower right, and a certain distance as the underlying shadow, the shift distance of the shadow is large.
4, select the middle layer text, press "Ctrl 1", call up the "Object" dialog box, in the Color bar, click the drop-down arrow on the right, select "Other", in the following " Selecting the Color dialog box to select a grayscale, such as color 250, with the same method, modify the underlying shadow color of 8.
Note: You can also choose any color, the choice of grayscale, because you can intuitively display an approximate shadow effect on the screen. If you select a color, you will do the following steps, otherwise it is done.
5. Type the "Pagesetup" command to open the page settings dialog. In the Print Device tab, confirm that "ACAD.CTB" under the "Print Style Table" column, then click the "Edit" button on the right, "Print Style Table Editor", "Print Style "column, you can choose the color selected by the intermediate layer and the shadow text." Use the object color "is changed to" Black "in the" color "on the right side, and the bottom layer shadow text" down "box Value is changed to 40, click Save and Off, and press "OK" to exit the page settings dialog.
Note: The operation here is the key to making shadow words. The value in the "Focal" box will affect the text shadow, the bigger the value, the more the shadow is more absent, the value is too small, the shadow is not clear, and it is generally more appropriate to be between "25 ~ 50". The intermediate layer text is due to the depth of performance, so it should be guaranteed to be black.
In the Print Style Table drop-down box, acad.ctb is used for color printing, monochrome.ctb is used for black printing, while grayscale.ctb is used to control grayscale printing, actually choose what kind of print style is not very The big relationship, because you can always adjust by clicking the "Edit" button, which is embarrassing the power of the AutoCAD2000 print function.
Relatively, adjust the depth and shadows in the Print Style Table, it is recommended to do this, and even if you choose the grayscale, you can still change the "color" to "black". Adjust the value in the "Flafers" box to control the final effect.
5. Type the "preview" command, you can see the effect. Note: Refer to this example, the "embossed word" effect is made. The premise is to draw a rectangle with a "Rectang" command as a background, and still copy the text. As a highlight and shadow, the original text and the high-light text color are the same background color, but the brightness of the highlight text is slightly higher than the original text, and the original text is adjusted to the left, the lower right position, pay attention to highlight and shadow characters are in the original text Below, finally, the print "down" value of the shadow text can be lowered.
--- Eleventh: Inside the image ---
Steps:
"Enter 45 in" Tilt ", click Apply, and close the dialog box.
Changing the font is inconvenient, unless you are in advance in the "Text Style" to define all Chinese characters you installed as a style, it is a name (! It is really full of support).
3. Select the copy "Pinkword" on the screen, press "Ctrl 1", open the Object Features dialog box, click the right small arrow in "Style" and select your newly built in the drop-down box. Style name, at this time, the font has been tilted, then click "Color" to select a grayscale, such as color 9, and press the "ESC" button twice.
Note: Maybe some friends will say why not directly set the slope directly in the multi-line text editor, is there a "slope" button, the reason is two, one is the inside of the inside of the TrueType font, for others The font does not work, and the other is that its tilt angle is ultimately determined by the settings in the "style" command.
Additionally, it is also possible to control the shadow of the shadow in the "down" box by the above example, in the "print style table editor" to black, then adjust the value in the "down" box.
4. Type the "mirror" command, mirror the sloping text, and then align with the original "inverted word".
--- Duen: Wave words ---
After the above drill, I believe that everyone has essentially mastered the use of the AUTOCAD2000 to make text effects, but don't forget that the AutoCAD2000 has a command that specializes in art characters. Why don't we move out of this magic? This is the "arc to the Qi Wen" command in the Express tool, of course, we have to create it.
Steps:
1. Type "ARC" command, draw an arc on the screen.
"
. " 4, type "ArcText" command again, select the image text, in the Open "Circular Writing Tool" dialog box, adjust the "position" in the "Format" menu ", "Direction" is "self-arrival", change the text to "you", click OK.
5, type the "MOVE" command, open the object capture function, select the mirror text arc, and connect it to the original circular arc. It is basically completed here. Of course, the writing is not very uniform, you need to use the "ArcText" command to constantly test the text spacing, and even the way to drag the arc clip is adjusted.
Note: The arc alignment word cannot be decomposed directly with the "TXTexp" command, you can use the "expLode" command to use the "txtex" command to process the text in accordance with the above production method.
To use this command, you can also create a "round word". Similar to CoreLDRAW fill in the path, the method is to adjust the way to select the text, or to adjust the intermediate clip, or in the Object Feature dialog Adjust the radius, start and end point angles.
well, the above introduces some methods that use AutoCAD2000 to make text special effects. These methods should be said that these methods are the most basic, and some words are not completely formed. Here is just to throw bricks, so that everyone can open ideas, don't put AutoCAD is only limited to the "drawing" app. At the same time, on the basis of mastering the above methods, you can create a bigger effect as long as it is slightly changed, for example, two or more or more or more or more or more kinds of methods in the above method. Of course, do you expect to use AutoCAD2000 to make font effects with photoshop compact, and you can make so many functions, but if you just want to give your drawings with a beautiful cover, then the above method It is more than enough to make its effect, so you don't have to come back. As for the professional requirements, or use Photoshop. Some practical skills of AutoCAD 2000
---- AutoCAD is currently the most widely used CAD software at home and abroad, the AutoCAD R14 rich drawing command, powerful editing function, three-dimensional modeling function, and good user interface are generally welcomed by the majority of engineering technicians. On the basis of AutoCAD R14, Autodesk has also launched a more powerful and mutually collaborative new generation of AUTOCAD 2000. When AutoCAD teaching and software development, I got some experience and summarized it for everyone to use AutoCAD 2000 reference.
1, cross cursor size change
---- Engineering Drawing is drawn according to the projection law. In order to facilitate "long pair of positive, high plane, width, etc.", when drawing, the cross cursor size can be adjusted. That is, using the options command or select the drop-down menu Tools (Tool) / Options, open the Options dialog, find the Display tab, by modifying the cursor and screen size in the Crosshair Size area Or drag the slider, change the default value of 5%, make the drawing window cross cursor size becomes large.
2, painted solid line
---- Technical Drawing National Standards have regular lines in mechanical patterns. There are many ways to draw rough lines with AutoCAD 2000. The easiest way is to use the lweight command. This command can be typed directly in the command line, or select the drop-down menu Format / LineWeight (line width), in the dialog box, set the required wire width, the default line width is 0.25mm, and the slider adjustment can be adjusted The screen is width display proportion, which is a transparent command. You can also click Object Properties Toolbar Tools icon Layers, in the Layer Features Management dialog box, linearly set line width like setting colors. Therefore, when the plotter is out, no need to adjust the pen width or the line width.
3, painting curve
---- When drawing the pattern, there is often a problem that painting intercept lines, coherence lines and other curves. Hand drawn is very troublesome, looking for special points and a certain number of general points, and the curve error is large. It is easy to draw a flat curve or space curve with AutoCAD 2000.
---- Method 1: Draw 2D graphics with a PLINE command, through a special point of the fold line, fit the FIT or SPLINE curve in the PEDIT command, which can become a smooth planar curve. Draw 3D in the 3DPoly command 3D graphics through a special point, the spline curve is fitted in the PEDIT command, which can turn into a smooth space curve.
---- Method 2: Create a three-dimensional basic entity (rectangular, cylinder, cone, ball, etc.), and then combined with Boolean (Boolean), and then use Drop-down menu View (View) / 3D ViewPoint (three-dimensional viewpoint), select different viewpoints to generate a standard view, get different view projections of the curve.
4, control entity display
---- AutoCAD 2000 common keyboard inputs three system variable control entities display.
ISOLINES: The fact that the entity is displayed in a wire box mode, and each surface on the entity is expressed in the form of a tire line. The number of fractures is controlled by the system variable, the valid value is 0-2047, and the initial value is 4. The larger the value of the fractal line, the more easy to observe the entity, but wait for the display time.
Dispsilh: This variable controls the display of the body profile, with the value of 0 or 1, the default is 0, does not display the silhouette edge, set to 1, display the silhouette side.
FaceTres: This variable adjusts the smoothness of HIDE (blanking), Shade (Color), Render, the effective value is 0.01-10.0, the default is 0.5. The larger the value, the smoother the smoother, but the Hide, Shade, and Render command wait for the display time level. It is usually increased when the final output is performed. 5, at the same time open multiple graphics files - During the drawing process, the user needs to view multiple graphics files simultaneously, and the AutoCAD 2000 provides the functionality of opening multiple graphics files simultaneously in a window (see Figure 5). Select a drop-down menu WINDOW (window) and select overlapping, horizontally or vertical arrangement of graphic files. It also provides graphics in a graphic file to drag directly with the mouse to another graphic file, greatly facilitating design work.
6, modify graphical properties
---- Drawing, using the property window, it is easy to easily modify the properties of a certain object in the graph. With the Properties command or select the drop-down menu Tools (Tool) / Properties, you can also use the hotkey Ctrl 1 to open the Properties dialog box, and select the modification of the modification by the table. 7, design center management
---- With AutoCAD 2000, you can easily preview, select, find, and use existing design results, you can get from your existing documents, local area networks and even internet. The desired graphics image resource is placed in the design center or dragged to the current graphics. You can use the ad geneter command or select the drop-down menu Tools (Tool) / AutoCAD DesignCenter, you can also use the hotkey Ctrl 1 to open the design center management window.
---- AutoCAD 2000 not only provides Object ARX, which has an object-oriented C application programming interface, but also provides Microsoft Visual Basic for Applications (VBA) to make developers to develop corresponding modules to customize and expand AutoCAD. Features. (See ActiveX and VBA Developer's Guide in AutoCAD Help. It is more stronger than the AutoCAD R14, editing, modifying, and network functions.

Block files cannot blow and cannot use some other common commands
This is caused by a wide LAN proportion that makes several commonly used commands, and blocks can only use the XP command. There are two ways to solve, one is to delete acad.lsp and acadapp.lsp files, the size should be 3k, then copy acadr14.lsp twice, named the above two file names, plus read only, will be immunized . To delete all LSP files in your DWG graphics. Otherwise you will infect others. Second, there is a software that specializes in killing the virus. Polygonal drawing
AutoCAD can create an equilateral polygon of 3 to 1024, and the multilateral shape can be selected when the number of edges is 3 to 1024, and the polygon is the internal circle mode or the outer cut circle. Generally, we are done directly into the edge length or select the endpoint. In fact, we can also draw them by specifying two endpoints in a parallel side, which is especially suitable for drawing some graphics, which is used to use "Edge" parameters in the "POLYGON" command. After we click the "Polygon" button or enter the "Polygon" command, we first need to enter the number of edges of the polygon according to the prompt, then select "Edge" parameters (you can enter only the first letter "E"), then capture two endpoints You can complete the polygonal drawing, which can greatly save our mapping time.
Use good parallel relationship command
Offset Command You can translate the specified distance, create a new object similar to the original object, which can operate, which includes straight, circular, arc, polynomous line, ellipse, constructor, spline curve Wait, when translates a circle, it can also create a concentric circle; when a closed multi-wire line can also establish the same closed graphic as the original object shape, because of this, the offset command is an AutoCAD editing command. A command with the highest frequency of frequencies. When using offset, users can create new sections in two ways, one is the distance between the parallel line, which is the most common way to use; the other is the point of the designation of the new line, select parameters "Through" THROUGH "(You can be abbreviated as" T "), capture a point as the pass point of the new line line, so you don't have to enter the distance between the parallel lines, and it is not easy to go wrong. Quickly make
The connection relationship between a graphic element in a graphic element is transitioned to another graphic element is tangent, remember that the author has just started learning the AutoCAD software, it is always awkwardly using the method of adding a radius plus or the radius to draw a phase. Cut round, it is really stupid now. In fact, when we use the drawing circle command, we use the parameter "TTR" to specify the tangent circle, then select the epitaxial object a and b circle, and then enter the transition radius, it can be easily cut. .
Special symbol input
We know "" of the diameter, indicating the "±" of the ground plane, and the labeling symbol "°" can be entered with the control code %% C, %% p, %% D, but if you want to enter other symbols What should I do? ? We can enter special characters through the "Character Map", the specific steps are as follows:
1. Enter the "mtext" command and create a text box, then open the "Multiline Text Editor" dialog box, in this dialog, we can see one of the four buttons on the right is the [SMBOL] button;
2, click the arrow in the lower right corner, open a drop-down list, we can see "Degress %% D", "Plus / minus %% P", "Diameter %% C", "Non-Breaking Space" , "Other" four options, selecting one of the top three to enter "°,", "φ" symbols directly, so that we can not remember the bitterness of special control code.
3. When you click Other, the Character Map Table dialog opens, which contains more symbols for users to select, and its current content depends on the font selected in the "Font" drop-down list, it The interface is entirely the Chinese interface we are familiar with, I believe that you should have no problem.
4. In the Character Map Table dialog, select the characters you want to use, then double-click the selected character or click the [Select] button, click the [Copy] button to copy the character to the clipboard, click [ Close] Returns the original dialog box to place the cursor in the position where the characters are inserted, and "Ctrl V" can paste the characters from the clipboard into the current window.
Custom Fill Pattern in AutoCAD 2000
In the AutoCAD drawing, the use of Hatch (pattern fill) commands is more frequent. Although the pattern library comes with the contents of the CAD, it is sometimes unable to meet our needs, then we can customize the pattern to fill.
AutoCAD's padding pattern is saved in a library file called Acad.pat, and its default path is installed in the / ACAD2000 / Support directory of the installation directory. We can edit the file directly with the text editor, add a custom pattern statement; you can also create a * .pat file yourself, save it in the same directory, CAD can be identified. Below, we will explain the method of custom patterns in AutoCAD 2000 with a newly created a rhombic pattern steel sheet pattern library file.
First, in the CAD, a rhombic pattern is made according to the national standard, and the dimensions of each part are marked (see Figure, you can click amplification).
See the following library wording standard format:
* Pattern-name [, Description] Angle, X-Origin, Y-Origin, Delta-X, Delta-y [, Dash-1, Dash-2, ...]
The first behavior header. This name will be displayed when the asterisk is the pattern name. When the Hatch command selects the pattern, the name will be displayed. In square brackets, the pattern is displayed by the "?" Option of the Hatch command. If the description is omitted, the pattern name cannot be a comma. The description of the second behavior pattern. There can be one or more lines. The meaning is: the angle of line drawing, the number of points of the X, Y axis coordinate, two-filled straight lines in the straight line of the linear family, the vertical spacing of the two filling lines, DASH-N is a straight line The length parameter, the positive negative value or zero, the positive value indicates that the length segment is a solid line, and the negative value indicates that the segment is left blank, and the zero can be taken.
Ok, we can start editing. Open a notepad, write as follows:
* Custom, Steel Plate GB / T3277-1991 68.4667, 0, 0, -9.8646, 25, 30.0213, 0.59 111.5333, 0, 0, 9.8646, 25, 30.0213, -6.59 68.4667, -9.8646, 25626, -9.8646, 25 , 30.0213, -6.59 111.533, 11.0191, 27.926, 9.8646, 25, 30.0213, -6.59 The four lines of pattern in this example correspond to the line segments A, B, C, D in Figure 1, respectively. In contrast, each item should be inextristic. Here is only to tell the value rules of Delta-X and Delta-Y, in order to make it easy, we set up the UCS coordinate system, determine the origin and the x-axis positive direction. The vertical spacing 25 of the lines A, E constitutes the vertical spacing 25 of the y-axis, and is also equivalent to the value of 25 of the OFFSET command in AutoCAD; if the line segment E is Offset by the line segment A, the line segment E is also relative to The line segment A moves 9.8646 in the x-axis negative direction, which is Delta-X.
There are still a few considerations below:
The pattern definition file can contain up to 80 characters.
AutoCAD ignores the text of the empty line and the right side of the semicolon. Based on this section, we can add copyright information to files, note or anything we want to join. For example:; copyright (c) 2000 by everyone. All Rights reserved. Finally, save the file, name Custom.Pat. Note that the file name must be the same as the pattern name.
At this point, I believe that friends have mastered the method of custom pattern. Now, you only need a little patience, you can edit a very complex pattern.
The method of calling the library file is: The attached page is the fill pattern and files I made, unzipped in / ACAD2000 / Support directory. Open AutoCAD, run the Hatch command, select the Customa in the Type column of the pop-up Boundary Hatch dialog, click the Swatch option bar, pop-up the Hatch Pattern Palette dialog, select the Custom tab, specify the custom.pat file we just created, at this time The preview of the filling effect is exhibited, which is the diamond pattern steel plate pattern we need. -------------------------------------------------- ------------------------------
AutoCAD Customization and Use
The variety of line type is one of the characteristics of the topographic drawing. It can be said that you have mastered the customization and use of the midline type in the topographic map, is equal to the full content of the AutoCAD line customization. The land, road, pipeline, etc. are expressed in special line types, although there are very small types of topographic patterns available for use in AutoCAD, but passed by AUTOCAD linear custom Function, handling these special lines is not a difficult thing. This paper introduces the customization and use of typical line types in the topographic map to help beginners master the customization and use of AutoCAD. Here, the lines in the topographic map are two major categories: one is a common line, like a high line, small road, power line, Great Wall line, etc., such a custom line, even more complicated, but They are classified as the same category because they are consistent, and they are called by the same way, they can use commands such as line, pline, is "real line"; another category is called multi-line (or Multiple lines) MultiLine. The multi-stroke is substantially arranged in parallel to the plurality of lines. After the definition is defined, the command MLINE is drawn by multiple lines, and multiple different styles of parallel line can be drawn. Multiline (multi-line) as a "line", which naturally has the advantages of "line" in use compared to commands such as OFFSET (offset).
---- One, how to customize a variety of universal sexages
---- You can divide ordinary line types into three categories: simple line style, string cable, line type with text string.
---- (1) How to edit and call the line file
---- Line file is a text file with .lin, you can use any ASCII text editor to edit, such as Windows NotePad Notepad. After editing the line type file, it is best to save in the AutoCAD path, such as the / support subdirectory in the AutoCAD installation directory, so you can enter the default call path of AutoCAD. In the line type text, you can insert any instructions, just add a double-semicolon ";;" in the line.
---- To call custom line style in AutoCAD, simply in the Line Type Call dialog box, you can pass the line file name, you can pass the page, select the confirmation .lin file.
---- (2) How to define a simple line style like administrative lines.
---- This line type is composed of repeated dashed lines, spaces, points, such as:
* County (wide .2), -.-. -.0, -1.0, 0, -1.0
---- The first line * is the marker, and the beginning of a line type definition. "County" is a line name, width .2 is used to prompt line width of 0.2mm. In the AutoCAD 2000, the toolbar of the line width is added, and it is placed next to the line type selection bar, which is a very useful function, which can easily set the width of the drawing line, so set the width in the line name. Tips are more meaningful. The new line width setting function on AutoCAD 2000 is only used for printout in the default. If you want to display it, you need to enter the "Format" menu, set "LINEWEIGHT", select "Display Lineweight ". At the same time, there is an interesting set "Adjust Display Scale", that is, the roughness of the adjustment line width display, which makes the line width setting, which is accurate when the print output is accurate, and is schematic when the screen is displayed. To make a better screen display effect with a width line. ---- The line type is drawn using a rough illustration of the line type shape, indicating that the county boundary is the shape of a dotted line. (The depiction is schematic, no effect on the actual line shape). The second line must begin with an alignment type. The number 2.0 represents the dash of 2 units, negative numbers - 1.0 represent a space of the unit, and the number 0 represents the point. ---- About line name, starting from AutoCAD R14, you can use Chinese characters as linear names, but in the R14 version, do not mix in English. After using Chinese name, if you must use letters or numbers, you can only Use full angle character format. There is no such limit in AutoCAD 2000. Limited to the width of the autocad toolbar, the width of the line display is not more than 10 Chinese characters.
---- (3) How to define the line type defined by the strip of the high voltage line and the wall.
---- In the definition of simple line style, insertion units, constitute a line type defined by a strip. If the high voltage line type is defined as:
* High voltage line, ---- <-.-> --- A, .001, [Circle, Map.SHX, S = 0.4], - 0.4, 1.8, [arrow, map.shx, s = 1], 11.0 , [Arrow, Map.SHX, S = 1.0, R = 180], 1.8
---- The second line to the fourth line is a row, and it is for writing to write. In the square brackets, the commonly defined part is referenced three times. Circle is a unit round, arrow is an arrow, and the two units are placed in the shape file called Map.SHX. ---- [arrow, map.shx, s = 1.0, r = 180] is this: arrow is the shape name, the arrow, map.shx is the model of Arrow (Shape File) Name, placed in the execution path of AutoCAD, S = 1.0 is the size in the arrow holder definition, R is rotation angle (rotation angle), R = 180 is inserted in arrow Turn to 180 degrees. The complete definition of the unit is as follows:
[Shape_name, shape_file_name, s = scale_factor, r = rotation_angle, x = x_offset, y = y_offset]
---- x_offset and y_offset are the offset in the X and Y directions in the X and Y directions, which generally defaults to wire type, and is not used by 0. In addition, the default value of R is 0, S is 1, only shape_name and shape_file_name cannot be default. ---- Specifically describe the definition of the high voltage line. The number of the second line A is 0.001, in order to move the drawing pen to the beginning in the shape of the shape, that is, the pen is short. A circular unit having a radius of 0.4 is then painted. After painting the circle, the role of the number-0.4 is a space of a 0.4 drawing unit to make the pen touch the circle, and the rear draw is not overlapped on a circle. Then draw a 1.8 long short line, and then paint an arrow--form unit. Behind the arrow is 11 units long shortline, and then a short line of the arrow turning 180 degrees and 1.8 units. ---- (4) How to define the line type with a text string
---- Insert a text string in a simple line style, constitutes a line type with a text string. This approach is used in the treatment of the topographic map. The following example typically reflects its definition method, the meaning of S, R, X, Y, and the reference of the counterfeit cells above. In AutoCAD 2000, the text string can use Chinese, but the Chinese font used in the drawing must be defined in the drawing graphics before using the line type.
* Direction line, --- Direction line ---- Direction Line ---- A, 20, -. 5, ["Direction Line", medium line, s = 1, r = 0.0, x = 0, Y = -. 5], - 5
---- (5), the shortcut of the shape (Shape) ---- 1. During the definition of the shape, there are two files in front and rear: .shp and .shx. .SHP is a text file, you can use any text editor to edit the shape-shaped definition .SHP file. Use the compile command to compile the .shx file into the .shx file in the confile command in the command line of AutoCAD. The. SHX file is a file that is configured directly to autocad. After transferring the .shx file with the load command, the use of the shape command can be inserted like a block in the shape of the pattern.
---- 2. The next paragraph three-line text is the definition of the city, the definition of the city, the definition of the city, and the first line double semicolon is explained, which can be used in any Chinese or English or character. The second line * represents a defined beginning, the line where the * is located is the title line of the general information, where "2" is defined in the Map.SHP, "6" is a number. Describe the line of byte length, "gwall" is the name. From the third row, it is a digital description, these numbers dominate the "virtual pen", controlling its movement and landing, relying on it to "draw".
;; City 跺 * 2, 6, GWALL 003, 5, 034, 040, 03C, 0
---- 3. Customize the defined line to be complex, there is a detailed introduction in AutoCad, it seems to be more laborious, fully learn that it is not available. However, here has a shortcut, I have debug a public LISP program make_shape.zip, it can automatically convert the drawn DWG graphics into a shape file, put it on the site http://personal.xfol.com/~7color and you Friends privately shared. However, friends using AutoCAD 2000 can not use this program, because the "Express" of AutoCAD2000 is self-created. "Express" is the upgraded version of "Bonus" in R14, "Make Shape" is in its "Tools". ---- II. How to draw multiple lines like the highway (Multiline)
---- The line body like the road and the highway is composed of several lines of different colors, which is ideal for drawing with Multiline.
---- Multi-line operation method is as follows: ---- 1. Select multi-line style "Multiline Styles" under the menu "format" column to enter its dialog.
---- 2. In the "Multiline Styles" dialog, the first item is "current", showing the existing multiple line name, which will be used as a new multi-stroke template, so The "lower triangle" selects the most symptom in the existing line style, the default is "standard". In "Name", the default display is the name of the selected template line, and should enter a new name and enter the appropriate description and description text in "Description".
---- 3. After pressing the "Add" button, add this line name to the current library. The setting of multiple lines begins below.
---- 4. Press "Element Properties ..." to enter the Element Properties dialog box to set each element in the multi-line.
---- 5. In this dialog, select the existing element (line) with the mouse to change its color (color), lineetype (line style), offset (offset), and "Offset" means the distance from the selected (line) element from the centerline, which is positive on the center, and below is negative.
---- 6. In AutoCAD R14, it enhances the ability to specify LineType (line style) here. This is a very useful feature. After pressing this function button, enter "Select LineType" to select line style, if current There are fewer optional lines, and can also be transferred to customized linear patterns through "LOAD ...". You can call the custom line style such that the multiple lines actually have the function of drawing the pattern strips and lace, and this can only be implemented by programming.
---- 7. To increase the element (ie, line), press the "Add" button and specify the three parameter values of its offset, color, line style. After all the lines are set, you can "ok" exit, return to the main interface "Multiline Styles", enter the "Multiline Properties" setting.
---- 8. Some of the options of "CAPS" are primarily determined in the shape of the wire in the multiline properties "Multiline Properties". Very valuable function is "Fill", select "ON", then set the fill color "color", the selected color will be filled in the multi-line as the background color.
---- 9. Example: Define "Highway" line style, use four black continuous lines, the offsets are 9.5, 8.5, -8.5, -9, and then fill it with brown.
---- 10. Save. After pressing the "Save" button, select a .mli multi-line library file to add this line to this MLI library. Note: Every line style should be saved once, because each "save" is the currently built.
---- 11. Use. In the menu "format" column, "Multiline Styles", enter its dialog, select the line name you want to use in "Current", if the line type is not in the list, you can transfer it through "LOAD ..." Button, select the MLI library file, and transfer to a predefined line style. The line type displayed in "Current" is the current default line style, which can be drawn using the Multiline toolban or "mline" command.
AutoCAD Chinese Character Tips Zhao Xusheng (Henan Water Conservancy Surveying and Design Institute Zhengzhou 450003) AutoCAD maps often use Chinese characters annotation, description; such as picture, legend, diagram, etc. How to easily process these Chinese characters, the author introduces yourself some of the experience skills to everyone. 1 Chinese character is converted into a multi-righteous line AutoCAD plug-in character shape generally there are two types of single lines (such as hztxt.shx) and hollow fonts (such as Hz.SHX), and there are small amounts of solid font (zipped in the output ). Chinese characters are a special entity, and it cannot be edited as a multi-ride line when the block is opened. Change the Chinese characters as a multi-righteous line, you can modify, edit, and hollow Chinese characters can also become a beautiful solid Chinese character via the pattern fill. The following is a method of changing a multi-ride line for the Chinese character font:
1) Add a new drawing device with the config command;
2) Select 3.autocad Fileoutput Formats in the plotter device; "pre 4.1) -by autodesk;
3) SUPPORT MODELS in 2.autocad dxb file;
4) Use the prompt to return the vehicle key by item;
5) Enter the new configuration plotter name: ASC;
6) Complete the plotter configuration;
7) Write the Chinese characters you want to edit on the screen;
8) Paint the current Chinese character graphic to the specified file (* .dxb) with a plot command (select ASC Drawing Device).
9) Turn with DXBIN to transfer the formed DXB file;
The related pictures of this topic are as follows:

Complete the Chinese character variable line procedure, the above method applies to various Chinese characters and English fonts. Figure 1 is a solid word that is filling in a hollow part.
2 Adjust the relative proportion of Chinese characters and alphanumeric characters in the same line
AUTOCAD, when a line of text contains Chinese characters and alphanumeric characters, the alphanumeric is larger than the Chinese characters, feels unrestrained, usually the alphanumeric should be slightly smaller than the Chinese characters, how to deal with this problem, first understand the word file. All fonts are stored in the form of ASCII font file (suffix SHP), alphabetical fonts and Chinese characters are stored in different font files, respectively. Let's first analyze the Roman font file: Romanc.shp front two lines:
* 0, 4, ROMNC Complex ...
21, 7, 2, 0
Among them: The first line is a font indicated file.
The second line 21 represents the uppercase letters (upper bounds of lowercase letters) extend 21 units above the baseline;
7 represents the lower bound of lowercase letters to extend 7 units below baseline;
2 Representative fonts Allow in the horizontal and vertical direction;
0 represents the end position of the file;
Upload code (21) also controls the ratio, in which 21 units are equal to one of the drawings in the text command. Therefore, the height of the English letters can be reduced by modifying the control ratio, such as change 21 is 25.
The following is an operation step (take the Roman font as an example):
1) Open the C: / ACAD12 / source / romanc.SHP file;
2) Modify the second line control ratio 21 is 25;
3) Compile Romanc.shp to Romanc.shx files in AutoCAD;
4) Copy the ROMNC.SHX file to the C: / ACAD12 / FONTS directory, renamed Romanc1.SHX;
5) Command: Style Enter
6) Text Style Name: HZ1 Enter
7) Press TYPE IT in the dialog
8) Font File: Romanc1, Hztxt Enter ... Complete font type configuration. The Roman font shrinks to the original 21/25, and its effect is shown in Figure 2. The proportion of various English fonts can be adjusted in the same way.
