¢ I, how to find its centrics when doing topology? It is the origin of automatically generated in the closed multilateral row (I think is the coordinate of the centric point) when generating a topology. Use the command to find it? Second, how to associate 2 external tables (eg, SQL2000) to do the topology is multilateral row? Use command! Manual can be realized. It is the command that is not used. Third, in a project, when the picture above is, the ID of a graphic is not changed (just before and after topology)? (I use the command PL to draw) four, how to attach the data of the external table to a multilateral row? Do you have multilateral rows that do it bring to the topology when doing a topology? Is it when it looks for a quality heart? Is it changed? V. How is the centroid of irregular multilateral rows? Is there any algorithm? ] Six, in a multilateral row, insert a piece of icon. When doing topology. Does the value of the pieces carry the topology of the multilateral row? How does its value capture? Seven, when doing the topology plus analysis, when the external table is output. It is a table defined by yourself. ? How is the data carrying it?
