Hi, i am undergrad student. I face a problem when i tried to modify the volume or face from the solidwork drawing that i imported. When ever i am modify or create a edge. I got an error message stated that can't operate with the associated non-real geometry. By the way, I am using IGES format to import into gambit. Any advide or help is truely appreciate. Thanks in advance.

When you import the file, Gambit must be creating virtual faces/edges. These are represented as v_face for example. You have to convert these to real geometry. Gambit isn't really very good with IGES. If you have an option of using Stp, STEP or parasolid, try that.

I tried to convert those v_face to real geometry, but gambit juz not let me convert it. Is it anything i should do before i convert it?

iges wont work..try step file instead of iges..i found step is ideal..

I tried other format...it work perfectly... but juz another question i wish to ask.... i wonder why after i delete the virtual volume in gambit...and it auto create another virtual volume again... it make me clean those short edges like no end... anyone can help??
