FacetCurve

This plugin can be used to "facet" 2D and 3D curves in AutoCAD: to approximate their curvature with a number of straight line segments.

The faceted output is in the form of a number of lines or a single polyline, as selected by the user.
Once loaded, the FACETCURVE command can be used to configure the application settings and to run the faceting operation on a particular curve.
