Importing surfaces shows "wrong" geometry

[GregPage]

I have been trying to import surfaces into Pro-E using IGES and ACIS files. Some of the surfaces do not import correctly, and show "flats" and "truncations" when displayed in Pro-E that are not present in the parent program (and since I can read the transfer file into another CAD program and replicate the original surface, they do not appear to be problems with the fidelity of the transfer format).

Has anyone imported surfaces from other CAD programs that might be able to help me determine if the surface is "wrong" or if Pro-E is just displaying something wrong.

I have found other instances where Pro-E draws something that does not actually exist in the surface (PTC agreed there was an error but has never responded with any kind of fix for it, and since the problem still exists in the WildFire release we have it appears they don't plan to do anything either) when exported to other programs, so have some reason to believe that it does not "draw" what it actually has in the internal data.

Thanks -Greg

Sometimes, especially for complicated shapes, the imported surfaces are not perfect in Pro/E, and there are gaps, overlaps, etc. In some cases a STEP file looks better in Pro/E, so I suggest you to try that one too. If this is still not perfect, choose the best one from them and fix it using "Import Data Doctor" which is part of Pro/E, where you have options like "healing", zipping gaps, etc.
