The routing node Sheet Metal – Stretch Forming provides the following options:

By default in starting point VPEs, the cost model assumes that material scrap (such as trim scrap) is not sold for credit. Administrators can customize the default with the cost model variable enableScrapMaterialCredit (false in starting point VPEs). With this setup option, users can override the default on a per-part basis.

Enabling scrap material credit increases material utilization and decreases material cost. The credit rate is specified as a percentage of the material rate by the material property Scrap Cost Percent. See Material Cost and Utilization for Stretch Forming.
