  6. Introduction Modification Die Design Check Addendum

  7. Tutorial I Using the Lift Gate part, we describe the basic procedures and techniques for the generation of an addendum in DFE. The part geometry is imported and a binder and an addendum is generated automatically. We show that the parametrically addendum generation will be adapted automatically, if the binder is modified. Finally, we describe the export of surfaces and Binder Trim.
