Hi all!
Having a bit of a heart ache with CAD. I have a CAD plan that has gradients and a street map.
I turned the contours into sandbox terrain with relatively little difficulty.
However, when I try to drape the street map over the terrain sketchup crashes. And I know what some of you are thinking, "drape a smaller area over the terrain then!" well, I tried that and it still crashes, even with one of the sub groups selected it crashes, with a single line selected it works... but seriously... I can't live my life individually draping lines onto terrain... If anyone has any anecdotes, advice etc... I'd be appreciative.

Wasn't able to upload the file, so I put it on rapidshare:
