Bezier #318

Do you support Bezier curve？

haplokuon commented 2 years ago

The DXF file format only has a definition for NURBS curves (Spline entity). While is very straight forward to save a Bezier curve as a Spline, to convert a Spline to a Bezier curve not so much. NURBS curve is a more generic mathematical representation of a curve than the Bezier. In other words, all Bezier curves can be represented as a Spline, but not all Splines can be represented as a Bezier.

Added the option to create a new Spline entity with a set of Bezier curves. At the moment, quadratic and cubic bezier curves are supported. In general, other than a third degree curve is rarely used.
