DYNAFORM 5.7.3 Training TutorialDYNAFORM 5.7.3 Training Tutorial

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 are generated automatically. There are descriptions

for some features of parameterization of DFE, the generation and export of

surfaces and Binder Trim, plus incremental analysis with Inc solver.

v. Create 2_LINE Binder

1. Click DFE menu.2. Select Addendum submenu and open the Addendum dialog box.3. Click New in the Master Profile group (See Figure 17).4. Select Profile Type: 3. Modify parameters: PartAngle=45, Bar Height=-10, PO

Do not close Addendum dialog box, and the next step will start from here.

Note: The basic parameters of the addendum (die fillet, back draft wall angle, etc.) are determined by the master profile parameters. The height and length of profile vary with the different distances between the part and the binder.
