I am working with Gambit preprocessor. I am trying to split one face with somes surfaces, perpendicular to the first one on the way that the intersection of all the surfaces with the first one compounds a closed curve.the bidirectional option is used. instead of building two surfaces I only achieve to create one surface which contains the intersection curve simply as another edge of this surface. Afterwards i try to create a volume with the stitch faces mode. the message "cannot create ACIS BODY, is it an open shell?" can be then read. that makes me think that the problem is based on the weird splitted face. know anyone this problem? can you help me? thank you very much

sounds like the splitting surface is just not big enough. If that is the case, Gambit created a 'dangling edge', wich is indeed a problem. You can detect dangling edges with the cleanup tools...

If you created the splitting surface only as a splitting surface, do it again, and make it a lot bigger.

If your splitting surface is a part of the geometry, then it mght be a good idea to first create the volumes, and do the splitting operations with the volumes. This is a much more solid as a procedure.

good luck,
