I'm having trouble mating the small ball in this assy with the chamfer in the seating hole. (I know I can draw it in place...) Any ideas? Thanks.

It should look like this (old proe assy I'm redrawing).

Slider mate plus tangent mate?

I just found the answer in one of Neil's old threads. Cylinder mate plus tangent did the trick. Thanks.

 This is one area that Onshape needs to do a little work yet. However, if I understand your question right, I think you can get what you are after with a cylindrical mate and then a tangent mate, make sure to select an edge from your base part for the tangent mate as a face causes it to fail. 
 There may be other combinations that would work as well, or perhaps someone has a better idea.

Actually the slider mate plus tangent is better. The cylinder mate allows the ball to move (I don't want that in this case).
