When sheet metal makes a transition from a bend to a flat surface or to another bend it tends to rip and tear. Lets you select the sheet metal body to which the corner relief is applied. Do one of the following. In the corner relief propertymanager under scope select the sheet metal body to which to apply the corner relief.

When you apply a relief option to the selected corner the list shows the option applied. For example if you make a partial flange as above using all the defaults the software makes relief cuts at the end of the bends as shown to the right. Though bend relief lengths and widths vary between projects they all share a common goal. Preventing tearing and part deformation during the bending process.

In general a minimum bend relief is equal to the material thickness plus the inside bend radius. Choose create relief in the sheet metal menu. To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.
