Hi, I'm now coding a tool to draw shapes like Visio. I notice that in Visio there are some functions to combine 2 or more shapes like Union, Intersect, Combine..., I don't know how to do it in C#. Currently I create a GraphicsPath, then assign some rect, ellipse to it, then create a Region and add the GraphicsPath to it. I can then fill the region, but for the outline, I don't know how to draw. And it's just similar to Union in Visio, what about other? Thanks alot for your help.
