Splitting curves where they intersect the surface

I have some curves that intersect with a surface, and I only want to keep the parts of the curves that are above the surface. I don’t know how to proceed after extracting the intersection points. Thank you.


Shatter the curves using the intersection points. Then for each curve segment, check if their midpoint has a Z height > the plane’s height, assuming the plane is parallel to the WorldXY:

Thank you very much. It worked :slight_smile:
