Hi Bryan, ok now when I re-read your post I think I understand that the drawing is a little wonky because you don't have the original drawing just some things written on the object?

But as long as the cone and sphere are supposed to be tangent where they touch it's enough to have cone angle, cone bottom radius and sphere radius. The station measurements aren't needed. However if it's not meant to be tangent then those slab thicknesses would probably come into play.
