ExtractControlPolygon
The commands that extract parts of objects can be used to
| ● | Create curves based on the geometry of the object. |
| ● | Open a hole or to separate a badly constructed surface from a polysurface in order to repair it. |
| ● | Separate the render or analysis mesh from an object in order to use the mesh for a different purpose such as rapid prototyping or rendering. |
| ● | Remove mesh faces in order to repair problems with a mesh. |
Fit a polyline through curve control points or a mesh through surface control points.
Duplicate a curve's curvature graph.

Duplicate curve control or edit points, surface control points, and mesh vertices.
Separate or duplicate polycurve segments.

Separate surfaces with errors from a polysurface.
Separate or duplicate a polysurface face.
