Curve To Mesh Grasshopper

Hi all,

I’m trying to create a terrain from contour lines. However, I can’t seem to make it work with neither the loft or the network options, cause the surface doesn’t go through all the drawn curves but just makes the approximation in some areas. I tried as well creating a mesh with WeaverBird but I’m not being able to make the function work since doesn’t assume the lines well (it always says the edge count is too low).

Thank you for the support!

Can you post your gh definition with internalized geometry?

A general logic is to subdivide the contour curves and compute a Delaunay triangulation mesh:

Which you can then remesh and/or project a NURBS surface onto: (8.0 KB)

First of all thank you for your answer. The problem with this solution is that my terrain has overlapping contour lines so the result has always some kind of error when creating a surface or a mesh. I uploaded the files, is there any way you would recommend to fix this? Thank you!
