49 //! Provides functions to build mechanical features.
50 //! Mechanical features include ribs - protrusions and grooves (or slots) - depressions along
51 //! planar (linear) surfaces or revolution surfaces. The semantics of mechanical features is built
52 //! around giving thickness to a contour. This thickness can either be unilateral - on one side
53 //! of the contour - or bilateral - on both sides.
54 //! As in the semantics of form features, the thickness is defined by construction of shapes
55 //! in specific contexts. The development contexts differ, however,in case of mechanical features.
56 //! Here they include extrusion:
57 //! - to a limiting face of the basis shape
58 //! - to or from a limiting plane
