Show Edges

Show Edges runs Rhino’s ShowEdges command and highlights the edges that decide whether a model can print. Three display modes:

  • All edges — every edge of the selected surfaces, polysurfaces, meshes, or SubD objects.
  • Naked edges — edges connected to only one face: the openings. A mesh with naked edges is not watertight and will fail as an STL.
  • Non-manifold edges — edges shared by more than two faces, the other classic reason a mesh will not slice.

The found edges are drawn highlighted with endpoint markers; you can zoom to them one by one, mark them with points for a persistent reference, and change the display color.

When Quick Check flags a mesh red, this is the tool that shows you where the problem actually is — and Automatic Repair usually closes it.
