When I use solidworks sheetmetal, I usually meet a problem that I can not imagine the intersection of two part in assembly. So I don't know the way cut part to make the intersection is nice. (Example the intersection of 2 spline curve sheetmetal.) With normal cut condition, the problem become too flexible. I spent 6 year for sheetmetal 3d cad, but I feel my skill is not upgraded. With your experience, please tell me the way to solve it?
