Evaluate surface not working

I am trying to draw a geometry within the boundaries of a surface. The geometry within the boundaries is dependent on a graph.
It works for the red planar surface. If I now try the same with the purple surface, which is not planar, it doesn’t seem to work anymore. I don’t know if the error might be in the construct point.

How are we supposed to know which group of code components and geometry (out of four :exclamation:) to look at? :roll_eyes:

Avoid passing values through text panels.

This looks like a problem with Relative Item? But maybe I’m looking in the wrong place :question:

Had the same issue in your thread two days ago: :roll_eyes:

You are supplying uv coordinates to the Evaluate Surface component that are outside the uv space of your surface (surface u domain is 0 to 1 you’re feeding values in range 0 to 138.43175)

Perhaps this is what you’re trying to accomplish.

Thank you very much, thats what i tried to accomplish! I assumed there was a problem with uv space but I didn´t know how to work around that.
