2D Contours and Profiles, the Basis for Rotation, Sweep and Extrusion Solids

To allow for 3D constructions various enhancements were made to the functions of the 2D graphic plug-in. The most significant enhancements are:

· Adjustable segmentation for spheres, ellipses and arcs.

· Automatic generation of contours, i.e. the formation of closed polygons from lines, polylines and arcs.

· Splitting polygons into line segments.

· Accurate scaling of polygons, 2D symbols and images.

Any contour can be created with the aid of these functions, and from it a solid for use in modeling.
