1. Several paintings of nuts
(1) Painting the six prism first, then rotate with a small triangle.
(2) Popular pictures, then chamfer on the edge of the cylinder up and down, and then pull it out to the outside.
2. When the naming part of the three-dimensional parts is modeled, the system automatically nams the beginning of its model tree, generally for the default form such as Part1, Part 2 .... When the part is modeled each time, the default part name in the model tree may have the same. Since the part is ultimately to be introduced into the assembled diagram, the part with the same part name cannot be called simultaneously in the assembly environment, and the repeated name is required to rename it. If a large part is assembled, this problem may be encountered many times. In order to avoid these unnecessary troubles, the author recommends that before performing the three-dimensional component modeling, the name of the part in the system default model tree will be used to save the name of the part file, which not only avoids the repetition of the part name. It is also possible to facilitate the storage of parts.
3. Tolerances are often marked in the engineering diagram of the part, and the Catia default font Sich cannot be marked as required, and it is marked in the form of ф39 0.05. At this time, the tolerance type can be set to Tol-1.0 and labeled with αcatia symbol font.
4. Right-click application
(1) When the size of the bidding hole in a semi-cross-sectional view, the dimension line is often half, and the extension line is only on one side. If you directly click on the outline of the hole, press the left button to confirm, the entire size line appears. You can click the right mouse button before you have not placed, select "Half Dimension", you can mark half of the size line.
(2) When the distance between the edges of the two rounds, when the two round arcs are selected, the system automatically captures the distance size between the two rounds. At this time, the right button is not placed before the size is not placed, in the pop-up menu Select the type of desired label in "Extension Lines ANChor".
(3) The horizontal or vertical distance of a slash is sometimes necessary to mark a slash, or a straight distance to a straight line, then you can select the object to the object to be marked, select The size type required in Dimension Reperesentation. The labeling of the two linear angles can also choose the desired labeling by "Angle Sector" in the pop-up menu.
5. Re-select the drawing, if the part is changed to the project, select the size of the drawings, such as the A3 is selected into a A4 paper, you can click "File" → "Page Setup" in the "Drafting" environment, in the pop-up dialog box Reselect the desired drawings.
6. Activation view In the drawing, you often need to cross-section, local amplification and breaking of a view. Before doing these operations, you must activate the view, beginners tend to ignore this problem, resulting in failure. There are two ways to activate the view:
(1) Move the mouse to the blue border of the view, double-click the mouse to activate the view.
(2) Move the mouse to the blue border of the view, right click on the mouse, and select "Activate View" in the pop-up menu.
7. Insertion of the box and title bar in the drawing
(1) You can make a template in the frame header bar of various drawings, insert each drawing. The specific operation is as follows: Enter the "drafting" state, select the drawing size, enter "Edit" → "Background", draw the picture box and title bar according to the required standard, and save it. In a picture, enter "File" → "Page Setup", select "Insert Background View" in the pop-up dialog box, select the corresponding figure box format, click "Insert".
(2) Can be inserted into the production chart box and the title bar before the projection and view. The specific operation is as follows: In the establishment of a good part model environment, click "File" → "New from", and select the box template file in advance by using the voted section of the project map, you can directly enter the plug-in frame and The Drafting State of the Title Bar. 8. Solving the icon to become English commentary, in the process of using the CATIA software, the tool icons that have met "Part Design" and "Assembly Design" environments have become in the form of English words, such as "Chamfer" becomes "chamferheader", stretching turns into "padheader", etc., it is extremely inconvenient to use. The reason may be that during the use of Catia, some temporary files such as CatSettings, CatTemp, etc. are generated due to operations, which may be saved automatically, which may have some effects on the use of Catia. So you should find these files in time and remove it. Another solution is to set "RESET" in "Tools" → "Options" for "for all the tabpages". After these operations, the author has changed back to the image of the image. Friends who encounter such problems may wish to try it.
9. When assembling the part in virtual assembly, it is best to completely constrain one part at a time, and the constraints of surface and face, such as plane and plane coincidence, the distance between the plane and the plane, center The line is coincident with the centerline, the angle between the plane and the plane, and the like. These constraint conditions are very stable assembly constraints. The edges and vertices of geometric graphics should be avoided as much as possible because they can easily change during the modification of the part.
10. How to call multiple calls multiple times to call a part multiple times, you can copy directly with "Fast Multi Instantiation".
