0044 //! Provides functions to build mechanical features.
0045 //! Mechanical features include ribs - protrusions and grooves (or slots) - depressions along
0046 //! planar (linear) surfaces or revolution surfaces. The semantics of mechanical features is built
0047 //! around giving thickness to a contour. This thickness can either be unilateral - on one side
0048 //! of the contour - or bilateral - on both sides.
0049 //! As in the semantics of form features, the thickness is defined by construction of shapes
0050 //! in specific contexts. The development contexts differ, however,in case of mechanical features.
0051 //! Here they include extrusion:
0052 //! -   to a limiting face of the basis shape
0053 //! -   to or from a limiting plane
0054 //! -   to a height.
