• C # reference coordinate system functions similar to modeling Abstract: In entity modeling software, various reference coordinate systems are often set and saved to facilitate model creation. C # similar functions are also available in plotting. But not as powerful as modeling software. In entity modeling software, various coordinate systems can be set and stored independently and called at any time. However, it can only be called in the form of nesting. When it is returned to the upper-level status, the skipped status will not be saved. 1 main command in Normal Mode: State = graphics. begincontainer (); Create a New Drawing status E. graphics. endcon... read the full text posted @ Addo read (883) | comment (0) Edit
