Is there a work around when mating a slot to a tapered hole? When using this feature you cannot select the surface of the tapered hole.
Can you not use an edge from the tapered hole?
You can create axis and mate to those or add sketch lines and mate to those...
All the parts are "referenced" and I do not have write access to them. I'm pulling these parts from our Library to create an assembly. If I create axis and add mates, as soon as I close the parts and open again, the mates will fail since the axis will not be saved in the part file.
You could mate the temporary axis from the tapered hole to the slot. Not ideal but you don't have to do anything to the part.
