Hellooo there. First time posting in the Grasshopper forum, so excuse the noobish question:

How would I create an attractor/ magnet between extruded curves and a rectangular surface? As in, I would like the extruded curves to range in height based on how close their control points are to the planar rectangle surface. I added a photo of where I’m stuck. Thanks for helping out!

The “pull poin” component is one possible solution. It pulls points (mid point of curve in this example) to a geometry (can be curves points etc). And it also gives you the distance between the original and the projected points. Than you remap the distance to the domain you want and do whatever you want.

Btw. upload your file next time you have a question (rhino geometry internalised), it’s just faster to help.
