I am working in sheet metal. I have an assembly that I am creating that has expanded metal sheet incorporated within. I am attempting to model the expanded metal by creating a flat sheet (0.030" thk x 3.5" x 14") and then incorporating slot cuts into the sheet.Each cut pattern (every other row) is offset by half the slot width creating thegeometry required for the expansion. My thought was to then create an "L" shaped tool (a punch), and use the top of the "L" along the length to stretch the part and expand the material. When I attempt to perform this operation I get an error "cannot intersect part with feature"? Does anyone have any thoughts about how to successfully create this material?
