awhile back some one on the list had posted a comment about Varicad's iges import being only 2D. i was wondering and tested a few others. i had a geodesic sphere that i had modeled in Catia and exported to iges. i was using it as a test case and it also comes up in 2D in not only Varicad but Rhino3D(Wine) also. i'd tested rhino before and can export 3D geometry to iges and get a 3D model back. the same is also true of the iges translator for catia. i think at least part of the problem is incompatabliities between iges versions/translators. just ramblings -- Oh, I have slipped the surly bonds of DOS, and danced the skies on Linux silvered wings. http://pfrostie.freeservers.com/cad-tastrafy/ //www.freelists.org/list/cad-linux
