Join the vertices of two different meshes?

Another possible approach with meshes is to use the script I posted here for inserting vertices into an existing mesh, and add all of the touching boundary points of each mesh to the other:
stitch_edges.gh (754.6 KB)


This can produce some very thin triangles where the points are almost but not quite coincident, so you might want to also run AlignVertices with a tolerance on the result.
