CAD drafting Delete Edge 6 Command line: NG_MESH_EDGE_DELETE

Using the command, you can delete edges of Submesh or Polyface mesh surface. Usually, it is used to delete “long” edges along the mesh boundary for correct contouring.

note: Since a TIN surface has triangle faces, deletion of edges will result in deletion of faces that contained them.
