i was wondering if anyone has a lisp for doing bend radiuses on metal. basically what i'm looking for is something with which i can either pick a material thickness or choose from a dialogue and fillet a corner according to this formula: outside bend radius=1 1/2x material thickness. inside radius= 1/2 of outside. i think this is the formula but i could be mistaken. anyway i'm wondering if someone has something similar or could help me write it as my first project? thanks
