Has anyone ever defined an o-ring as a flexible component? We use round gasketing all over the place at my company, and I'm sick of ignoring those part interferences during my interference checks. What I'd like to do is model the o-ring as a flexible component, so when it's installed in the assembly, it compresses itself. If possible, I'd like a part which a) has inherent diameters defining the free shape (knocks ellipses out of the running), and b) takes groove side walls into account. Thanks!
