we have to build vacuum forms and currently we do them in auto cad. We wanted to chage how thay are assembled with a puzzle piece design. as we convert from auto cad to sw we are try to get the new stuff created in SW. i am trying to make a tru parametric out of it. things lake when the width of the jig is entered it automatically puts the amount of ribs and or rib supports in. does any body have any pointers on it. I have a couple years of sw and always still learning.
