- C # drawing function similar to the reference coordinate system modeling
Abstract: The solid modeling software, often save the settings and functions of the various reference coordinate system, easy to build the model. C # drawing has such similar features. But no less powerful modeling software. Solid modeling software can be independently set and save various coordinate systems, and at any time. And here only in the form of a nested call, when returning to the previous state, the state is no longer skipped saved. 1 Normal mode major commands: state = graphics.BeginContainer (); build a new drawing state e.Graphics.EndCon ...
