ExtractMeshEdges

Toolbar Menu

Extract Mesh

Not on menus.

The ExtractMeshEdges command separates edges from the parent mesh determined by an angle between mesh face normals.

The command may help if you have a mesh that came from a polysurface but no longer have the polysurface. Using the command with the Unwelded option creates polyline approximations of where the edges of the polysurface were.

Note

Steps

Command-line options

Extract edges by

Unwelded

Extracts edges with coincident vertices.

Break angle

The angle between the face normals of adjacent faces.

Greater than

Specify a minimum break angle.

Select Edge

Specify an example edge to set the minimum break angle.

Less than

Specify a maximum break angle

Select Edge

Specify an example edge to set the maximum break angle.

Join results

Joins the resulting curves.

ExtractNonManifoldMeshEdges

Toolbar Menu

Not on toolbars.

Not on menus.

The ExtractNonManifoldMeshEdges command separates from the parent mesh non-manifold faces.

Nonmanifold edges

Edges of polysurfaces or meshes that have more than two faces joined to a single edge are non-manifold.

The illustration shows polysurfaces with non-manifold edges highlighted with the ShowEdges command.
