I've tried all the export options for dwg such as export as section slice and 2d graphic but with the first option i get the 2d cad export ok reply and when i try open it in auto cad it is blank where as with the 2d graphic dwg export option sketchup just crashes or becomes non responding.
I'm not sure if the fact that i have imported texture images in to my material option that are not skp default materials, has anything to do with it?
Hope that makes sense.
Thanks for the help guys.
