Hi James
Many thanks for the help...
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) ?
- you can create parametrically, with values on slider,
a Range -> (Domain / integer) ?
-and you can , always create parametrically ,
a Series of numbers -> Start Number / Interval / Number instances ?

thanks in advance
have a nice day
