Hi mfalinsk,
You can create 3D parametric surfaces of all 6 planes, then plot their matrices into one 3D graph layer.
For example, to make a matrix of the rectangle top plane with X=[6.25, 258.9], Y=[0.53, 32], Z=[160, 4500]:
1) Choose "File: New: Function Plot: 3D Parametric Function Plot".
2) In the appeared dialog, enter:u: From=6.25, To=258.9;
v: From=0.53, To=32;
X(u,v)=u; Y(u,v)=v;
Z(u,v)=4500
Now, you get a matrix sheet (say, MSheet1 in Func1) with 3 matrix objects.
After defining all 6 matrix sheets, you can insert all sheets using Layer Contents dialog box as usual.
Did it work?
