Hi all,
I have a mesh plane created in Rhino and I would like to read the face normal of the triangular faces.
But when I use DeconstructMesh as shown above, it gives me the faces of the quad faces.

How can I convert the mesh into a triangulated mesh with triangulated faces?

Face Normals should do the job, getting quads is weird.
Could you attach your mesh gometry ? (Rhino file or internalized GH file)

Here you go.

Edit: I just realize if I triangulate the mesh before putting into grasshopper, FaceNormal reads the mesh as triangulated mesh.

It’s a mistake on my part.
