The hinge mate requires selecting two concentric features to mate and two coincident features to mate. Interactively this is easy because you can tell SW which mate the two features you are about to select will correspond to by choosing either the concentric or coincident dialog box.
How would this work using the api? Do you just select the four features you want before invoking addmate3() and it sorts which is which?
The hinge is just a concentric plus a coincident mate so I could apply the two individually without issue, but having the hinge as an available option is confusing to me.
