I am running 2011 c3d on windows 7 with 15 GB of ram.
An error message I get is "reading triangles from file" and the program locks up to where you need to do a reset on the computer. I have an existing ground surface that is data shortcut into the file I am opening when I get this error. The existing ground surface is about 5 mg in size. I'm not sure if this is causing the error. Any information or help on this appreciated.
What happens if you open the Drawing with RECOVER Command in Civil 3D?
Does that work?
