Grasshopper project curves on mesh surface

the grasshopper project component works to project curves onto a brep or surface, not a mesh surface
is there a way to curves project onto a mesh surface?
the mesh surface is a result of a kangaroo application draping a mesh planar surface onto a sphere

Hi @cshea,

Attached is a custom C# component you can use. (12.5 KB)

Hi Dale
Thanks!!! it works well!!!
wish it was always so straight forward!!!
really appreciate this!!!

This is very cool @dale, Any chance you could make a variant of this to use the pull curve command instead of directional projection? it’d be super handy for a Curve-based SubD thing we are doing.

Hi @dale, thanks so much. that works great!

Hi, @dale
I’m trying to do the same, but I can’t download the attached file you gave to Cshea.
Can you please help me?

Hi @nrangel91, You should be able to download that file now.
Let us know if that is not the case.

Hi there,

Thank you so much for that C# component! However, I’m having a problem and I’m not sure where it lies:

I modelled a little mesh with Kangaroo and I wanted to project some curves on it. The C# does almost the whole work but somehow not in the central parts:


I don’t have a clue of why this is happening or what I could do, so any help would be appreciated:)
