```Hey...
Here's some new equations that should help you find the middle of a
rectangle with coord's Xa-d, Ya-d, Za-d...

Xe=(Xa+Xc)/2 'Or the 2 coord's on opp corners
Ye=(Ya+Yc)/2 """""""""""""""""""""""""""""""
Ze=(Za+Zc)/2 """""""""""""""""""""""""""""""
Xf=(Xb+Xd)/2
Yf=(Yb+Yd)/2
Zf=(Zb+Zd)/2

The 'e' and 'f' coord's SHOULD always be the same, and the midpoint
of the plane.  To find a point 64 above that, i'm still working on.
