1. Ability to create and flat pattern complex bends

2. More in depth calculation with punch features to show possible deformation/shape

3. Ability to Miter ect. between 2 sheet metal parts in the assembly environment

4. Have additional Sheet Metal Material Library with set Gauges 

     a. (Possibly?)Be able to select gauge and material for the Sheet Metal Rule and it understand the thickness
