Faceted models

Faceted models are surfaces made of polygonal facets. They may be created by extruding or rotating a polygon. Most often, they are made by converting from a B-spline or Bézier surface.

One use for faceted models is a temporary representation for surfaces when computing areas or volumes. The required conversion is done with the command SURFACEÞChange:Faceted.

A second use is to transfer your surface model to another design system or manufacturing system in particular rapid prototyping systems, which use the STL file format.
