Sheet Metal Modeling
Sheet metal modeling in CAD/CAM systems means creating and editing 3D models of sheet metal parts. Flat patterns are transformed into complex 3D shapes by bending, stamping, drawing, and other manufacturing operations. In this article, we present the basic concepts of the sheet metal modeling functionality...
