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.
Command-line options
Extracts edges with coincident vertices.
Extracts edges based on the angle between the face normals of adjacent faces.
Specifies the minimum break angle.
Pick a sample edge to set the minimum break angle.
Specifies a maximum break angle
Pick a sample edge to set the maximum break angle.
Sets the amount the value changed by each arrow click.
Creates polylines from the extracted line segments.

The ExtractNonManifoldMeshEdges command extracts the mesh faces that have non-manifold edges from a mesh object.
Edges of polysurfaces or meshes that have more than two faces joined to a single edge are non-manifold.
The illustration shows a mesh and a polysurface with non-manifold edges highlighted with the ShowEdges command.
Command-line options
Only extracts the faces with non-manifold and naked edges.
Extracts the faces around a non-manifold edge shared by faces ≥ the specified number.
In the illustration, each red edge is shared by four faces. Each blue edge is shared by three faces. When MinimumFaceCount=4, only the faces around the red edges are extracted.
