Hi Al

>>I need to ask other, maybe you could help my;
- How can I enter a domain of U and V in the Math node pt
into Fx3D Graph exists a field (Min) and (Max) ?<<

An earlier iteration of MathArray node had inputs for UMin, UMax, VMin & UMax.
These have been removed with the name change to MathPoints.

I believe that Max is developing Range and series nodes to satisfy this requirement
and the others you mentioned We need to wait and see.
