Sheet metal parts with a minimum of 0 9mm to 20mm in thickness can be manufactured. Do one of the following. To open the corner relief propertymanager. Click insert sheet metal corner relief.

When designing parts for laser cutting one should not make holes smaller than the thickness of the material. The selected items can be a 3d solid with sheet metal features a face or a hard edge of the solid. Relief height is generally kept greater than two times of sheet thickness plus bend radius. Bend relief is provided at the end of bending edge in sheet metal design to avoid any crack tearing in the corner.

There are two things that can be done to reduce the risk of sheet metal tearing. In general a minimum bend relief is equal to the material thickness plus the inside bend radius. Rip corner relief and conversion creo creoparamet. If it is ok for the metal to rip the minimum bend relief is zero.
