If a 3d solid is selected the command recognizes the places where corner or bend reliefs are needed and creates them automatically. Click corner relief sheet metal toolbar. You can apply corner relief automatically to all corners or manually to individual sets of corners. Relief height is generally kept greater than two times of sheet thickness plus bend radius.

First utilize minimal bend radius of internal bend radius equal to material thickness. Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured. Understanding corner relief design flexibility2 the contour flange is created using the auto miter option and the seven edge loop of the polygon is selected. Click insert sheet metal corner relief.
