Using Auto Reliefs

The software automatically adds relief cuts wherever needed when inserting bends if you select Auto Relief. The software supports the following types of relief cuts:

  • Rectangular

  • Tear

  • Obround

If you want to automatically add Rectangular or Obround reliefs, you must specify the Relief Ratio.

Tear reliefs are of the minimum size required to insert the bend and flatten the part. You can select Rip or Extend .

Relief Ratio

The distance d represents the width of the Rectangular or Obround relief cut and the depth by which the side of the Rectangular or Obround relief cut extends past the bend region. The distance d is determined by the following equation:

d = (relief ratio) * (part thickness)

The bend region is represented by the dark gray area of the diagram.


The value of the relief ratio must be between 0.05 and 2.0. The higher the value, the larger the size of the relief cut added during insertion of bends.
