Placing a Sphere in a Box

Check this earlier thread:

Precision movement of a sphere

I am trying to move a sphere to an exact point on another model. I want to grab the center of the sphere and move it to an intersection. The picture below shows the situation. I want to use the sphere to intersect the two shapes to cut a dimple into the rectangular prism. .

Edit: Gee, I had a better example using two spheres, but I can’t find it. Still, this is the general method.
