GH Version: 0.6.0059/0.7.0014
This definition takes one or more closed polysurfaces* and makes a closed polysurface shell representing the edges. Tested on simple polysurfaces with coincident verticies. Mix generated result with Giulio Piacentino’s Weaverbird for a smoother mesh version.
Definition tested in GH 0.6.0059 and 0.7.0014.
