A couple of days ago I was able to export from Civil 3D 2007 to 2004 dwg
format. Now it freezes on me during the export process. I have added more
profiles and pipe networks since. The only other thing that i have changed
is setting PROXYGRAPHICS to 1. I have tried setting it back to 0 but that
doesn't work either.
Any ideas on why its not exporting now?
