any help ?

Maybe give the U and V input a value between 0 and 1

4

already it is zero and zero but the points are outside the surface

5

Try 0,5

6

0.5 is ok is come in the center. but i need a range of parameters for 0 to 1

7

Use a number slider and set the max value to 1 and the step to 0,1?

If you generate the surface by patch it will not be trimmed. Try lofting between the even or odd edges instead, or generate your surface at the origin so the UV parameters are trimmed and transform the points (or surfaces before making the points).
