package BRepFeat 

        ---Purpose: BRepFeat is necessary for the
            -- creation and manipulation of both form and mechanical features in a
            -- Boundary Representation framework. Form features can be depressions or
            -- protrusions and include the following types:
            -- -          Cylinder
            -- -          Draft Prism
            -- -          Prism
            -- -          Revolved feature
            -- -          Pipe
            -- Depending on whether you wish to make a depression or a protrusion,
            -- you can choose your operation type between the following:
            -- - removing matter (a Boolean cut: Fuse setting 0)
            -- - adding matter (Boolean fusion: Fuse setting 1)
            --   The semantics of form feature creation is based on the
            -- construction of shapes:
            -- -          for a certain length in a certain direction
            -- -          up to a limiting face
            -- -          from a limiting face at a height
            -- -          above and/or below a plane
            -- The shape defining the construction of a feature can be either a
            -- supporting edge or a concerned area of a face.
            -- In case of supporting edge, this contour can be attached to a face
            -- of the basis shape by binding. When the contour is bound to this face,
            -- the information that the contour will slide on the face becomes
            -- available to the relevant class methods. In case of the concerned
            -- area of a face, you could, for example, cut it out and move it at
            -- a different height, which will define the limiting face of a
            -- protrusion or depression. Topological definition with local
            -- operations of this sort makes calculations simpler and faster
            -- than a global operation. The latter would entail a second phase of
            -- removing unwanted matter to get the same result.
            -- Mechanical features include ribs - protrusions - and grooves (or
            -- slots) - depressions along planar (linear) surfaces or revolution surfaces.
            -- The semantics of mechanical features is based on giving
            -- thickness to a contour. This thickness can either be unilateral
            -- - on one side of the contour - or bilateral - on both sides. As in
            -- the semantics of form features, the thickness is defined by
            -- construction of shapes in specific contexts.
            -- However, in case of mechanical features, development contexts
            -- differ. Here they include extrusion:
            -- -          to a limiting face of the basis shape
            -- -          to or from a limiting plane
            -- -          to a height.
