rough offset restriction


Super Moderator
My guess is (I don't know for sure) this deals with attempting to offset a surface that is not smooth. (Surfaces containing sharp corners and tangent discontinuities are examples that may cause offset problems).

Were you able to find the Knowledge Article that was referred to?

Do you have a design situation where you've run into this problem? Or are you trying to learn all the little details of CATIA modeling?

I have already created a successful rough offset surface from a G0 continuity surface. The reference surface was an extrude of a polyline.

Knowledge base is accessable here, but I don't have a DS passport don't you?

No, I've not run into this problem in designing. I'm just a curious person about the details of CATIA modelling.
