Curves to follow form of surface in Grasshopper

Hi All,

I have a script that creates a line through a series of points on a surface, however the line travels directly to each point. is there a way to make the line travel along the surface to the next point? i know this might be asking a bit much!

Thank you for any help!

Use the Pull Curve component.

Also, is there a reason you are working 46,140 units away from the origin?

that is amazing, thank you very much for this!

Yes thats a good point, i should have moved it back to zero. it was part of a bigger project that I was working on, i got rid of the other components, to make my question clearer, but forgot to relocate the remaining items!

Thank you again!

do you know if there is a way to do the same thing with a brep instead of a surface?
