Rod following the surface of golf ball

Is there a way to constrain a rod so that it tracks the surface of a dimpled golf ball? The diameter of the rod would be smaller than the diameter of one dimple. The golf ball would be able to rotate on any axis with the center remaining fixed. The rod wouldmove up and down along its center axis and act like a follower. The surfaceof the rounded rod end, would always justtouch the surface of the golf ball. The rodwould be able to dip into a dimple before the surface constraintsare met. I am not able to find a suface constraint to make this happen as the two touching surfaces are not always tangent.


Using the Pairs Clearance in the Model Analysis, Pro-E can quickly calculate the clearance or interference between any two parts. Is there any way to create a relation in the Component Placement window, which would adjust the height of the rod until the clearance is zero?


Even with Mechanism, a follower must track a datum line and there seems to be no surface to surface constraint allowable.
