What is it about?
A hybrid approach that uses a combination of the surface-visibility algorithm and the silhouette-detection algorithm was proposed for the automatic generation of parting curves from free-form CAD models. It can identify the loops of a parting curve faster and more accurately than existing algorithms and CAD systems.

Why is it important?
Using the free-form surfaces as the input for silhouette extraction, the proposed algorithms are robust and adaptable for use with various downstream CAD/CAM systems and applications currently used in industrial product/mold design and manufacturing.
Perspectives
The paper breaks the limitations of the existing commercial 3D CAD/CAM software packages in guarantee of successful generation of parting curves for complex geometry with free-form surfaces.
