Extract object sub-elements
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.
Extract curves from a surface or polysurface
