Extract Mesh Edges

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

Extract edges by

• Unwelded: Extracts edges with coincident vertices.

• Break angle: Extracts edges based on the angle between the face normals of adjacent faces.

Greater than: Specifies the minimum break angle.

Less than: Specifies a maximum break angle

Increment: Sets the amount the value changed by each arrow click.

• Naked: Extracts the edges that have only one face associated.

• Join results: Creates polylines from the extracted line segments.
