0036 //! MakeRevolutionForm Generates a surface of
0037 //! revolution in the feature as it slides along a
0038 //! revolved face in the basis shape.
0039 //! The semantics of mechanical features is built
0040 //! around giving thickness to a contour. This
0041 //! thickness can either be unilateral - on one side
0042 //! of the contour - or bilateral - on both sides. As
0043 //! in the semantics of form features, the thickness
0044 //! is defined by construction of shapes in specific contexts.
0045 //! The development contexts differ, however,in
0046 //! case of mechanical features. Here they include extrusion:
0047 //! -   to a limiting face of the basis shape
0048 //! -   to or from a limiting plane
0049 //! -   to a height.
