Lately, I've been trying to create a carbon bike frame with bezier
patches.  It's going relatively well (and SLOWLY), but there's one thing
I can't stand.  I've found that I only need the control points on the
corners (marked by X's).  All that really matters is that the patches
are seamless and the center points are not necessary for this.

It seems like there should be a way to interpolate those points without
having to enter them manually.  Has anyone ever written a macro to do
this?  Is there a simple way around this?

Thanks in advance.
