no flat face in imported step or igs file

[williwang]

Hi all, good day!!!

I am suffering from not being able to get flat face in imported igs or step files.

Original UG file contains flat faces. after importing I cann't use them for assembly because they are not considered flat faces any more. Also I cann't create sketch on the surface. If I measuer one of them, CATIA shows surface symbol instead of face.

I have tried to modify igs settings, it didn't work.

Anyone can tell me how to solve the problem?

I would look at the sending system as the receiving system can only translate the entity types available in the file. Go to the export options/advanced tab. Toggle the 2 options for surfaces, write test files. Do you know for sure the surface data in UG is planar?

We typically use step to transfer files from UG - Catia.

Yes, I changed UG igs settings. It worked. There is an option, in UG, called Japanese Automotive Compliant (JAMA). Tick on this option. New igs file does give flat face now, but I lose all the cylinder surfaces. So, I can not get flat and cylinder at the same time. So strange. It only happen to some UG model.
