I'm wanting to show a SurfaceGraphics with two Graphics3D objects in
Mathematica, and found it's not easily possible.  The context of
the problem is showing a 2-input, single-output system response
and wanting to combine the desired response points with the
SurfaceGraphics plot generated by Plot3D.

The Mathematica Reference Guide (Appendix B, Mathematica, p. 685)
says that when using the Show command, only plots based on Graphics
and Graphics3D can be combined.  Sounds like the final word on the 
matter, but I was wondering if anyone's done anything clever in
this regard, or can suggest other packages to do the task.

I would wonder if there is a way in Mathematica to change a SurfaceGraphics
object into a Graphics3D object, that I don't know about (mmm...).
It seems fairly intuitive that Mathematica is ultimately treating the 
SurfaceGraphics object as a Graphics3D object.

If you could respond to me via e-mail, then I'll do the responsible
thing and summarize and repost.  If the solution is simple then
post to sci.math.symbolic, as I'll read that more than comp.graphics.

Thanks for your time.

Steven Young.
