Help with Delaunay Mesh problem

[Brian_Washburn]

Hi @jdelavaulx ,
This reminds me of this thread:

Project one mesh onto another mesh

Hi @Alfredo_Peña , Does the following work for you? It’s a C# version that builds on what @AndersDeleuran made, but uses all the naked edges, instead of just the outer edge for projecting and splitting the terrain mesh. The resulting meshes of the splitting are filtered based on if a ray cast from the center of the first face hits the original projected mesh, you add it to the final mesh. 20240831_MoveToTopo_BW.gh (618.7 KB) [image] [image]

C#

List<Curve> curves = new List<Curve…

Below is a version which uses curves as input instead of the meshes from the previous thread. Note, the outer boundary needs to be the first curve in the list.
