53 | //! around giving thickness to a contour. This thickness can either be unilateral - on one side |
54 | //! of the contour - or bilateral - on both sides. |
55 | //! As in the semantics of form features, the thickness is defined by construction of shapes |
56 | //! in specific contexts. The development contexts differ, however,in case of mechanical features. |
57 | //! Here they include extrusion: |
58 | //! - to a limiting face of the basis shape |
59 | //! - to or from a limiting plane |
60 | //! - to a height. |
