extract surface isocurve using unevenly spaced points

Hi guys,

Thanks to Dirk's definition i managed to get unevenly spaced points on a curve using a graph mapper.

I tried to use these points to extract isocurves from a surface but i get this very strange result.

I tried doing the same operation with a planar surface and i got the same result.

I hope someone could help,

Many thanks

Those curve points are in XYZ, you need UV values within the range of the surface...try using the Surface CP and use the uvP... or construct the logic for the UV points utilizing the domain of the surface.

Great, it works now!
Thanks again Luis.
