3d cutaway plane to 2d

[Anonymous]

I have a model, where I've made the mesh to act as a roof (the thickness comes with another mesh and SEO). Now - as the roof is complex and funny, I did some 3d cutaways from different heights. Is there a way I can show the cutaway lines on 2d?
Tried 3d export from 3d, but when importing the dwg file i got all kinds of lines but not the right ones.

Short answer: in the 3D Window, select the Marquee Tool, flat marquee option, select the area around the area and copy. For a fuller discussion see my post in this thread: Getting contour lines from a mesh
