Smoothing Boundary Curves

Many CAD/CAM processes utilise algorithmically generated boundary curves for a variety of purposes. For example, milling applications often use boundary curves to limit regions where a cutter may go, die design utilizes boundary curves to define parting lines on the object, and reverse engineering utilises boundary curves to segment the surface. However, in various cases, the boundary curves computed do not have the desired smoothness for downstream processing, and should be smoothed to improve their quality.
