locate mating surface


how can i get an accurate mating surface of A to B, if A is ofsetted to B?
by increasing offset distance in small values could help a little but i'm looking for shorter and more accurate method.

Assuming there are other constraints to position both surfaces, use an Offset constraint between the centerpoint of the sphere and a contact point that you have to add on the surface. The offset distance = offset + radius of the sphere.

So A and B are just two irregular surfaces? And you want to constrain these so there is a fixed distance between them? Could you provide another picture showing a better example of what you want?
