Thought I would be clever and model an o-ring as an ellipse using a sweep. Both the trajectory and cross section are ellipses with the major and minor diameter equall. This way you can show the o-ring as an oval in an assembly by making it flexible. NOT! The o-ring is driven by a family table for the trajectory major and minor diameters. Pro will not let you make a family table dimension flexible. Is there another way to accomplish this other than the obvious of making a seperate part. There are about 40+ instances in the generic and the drawing is table driven.
Thanks

I'd just use a revolve, they're a lot simpler than a sweep. I made a family table of O-rings like that years ago, that were flexible to account for "squish" and the angle of grooves.
