I actually don't know. It's easy to perform a solid boolean operation, but cutting holes is harder. We don't have a top-level function for it. I'll ask in Seattle.

Yes, the Rhino.Geometry.Brep type has a set of static Solid Boolean functions. You'll need to make sure both your surface and your cube are converted to Breps first, and then you can call:
