| 17 | class MakeRevolutionForm from BRepFeat inherits RibSlot from BRepFeat |
| 18 | |
| 19 | ---Purpose: MakeRevolutionForm Generates a surface of |
| 20 | -- revolution in the feature as it slides along a |
| 21 | -- revolved face in the basis shape. |
| 22 | -- The semantics of mechanical features is built |
| 23 | -- around giving thickness to a contour. This |
| 24 | -- thickness can either be unilateral - on one side |
| 25 | -- of the contour - or bilateral - on both sides. As |
| 26 | -- in the semantics of form features, the thickness |
| 27 | -- is defined by construction of shapes in specific contexts. |
| 28 | -- The development contexts differ, however,in |
| 29 | -- case of mechanical features. Here they include extrusion: |
| 30 | -- - to a limiting face of the basis shape |
| 31 | -- - to or from a limiting plane |
| 32 | -- - to a height. |
