class MakeLinearForm from BRepFeat inherits RibSlot from BRepFeat
---Purpose: Builds a rib or a groove along a developable, planar surface.
-- The semantics of mechanical features is built around
-- giving thickness to a contour. This thickness can either
-- be symmetrical - on one side of the contour - or
-- dissymmetrical - on both sides. As in the semantics of
-- form features, the thickness is defined by construction of
-- shapes in specific contexts.
-- The development contexts differ, however, in case of
-- mechanical features. Here they include extrusion:
-- - to a limiting face of the basis shape
-- - to or from a limiting plane
-- - to a height.

---Purpose: contour W, a shape Sbase and a

-- elements in the construction of the rib or groove.
-- Direction and Direction1 give The vectors for
-- defining the direction(s) in which thickness will be built up.
-- Fuse offers a choice between:
-- - removing matter with a Boolean cut using the
-- setting 0 in case of the groove
-- - adding matter with Boolean fusion using the
-- setting 1 in case of the rib.

---Purpose: Initializes this construction algorithm.
-- A contour W, a shape Sbase and a plane P are
-- initialized to serve as the basic elements in the

-- up are given by Direction and Direction1.

-- - adding matter with Boolean fusion using the setting 1
-- in case of the rib.

---Purpose: Performs a prism from the wire to the plane along the

---Purpose: Limits construction of the linear form feature by using
-- one of the following three semantics:
-- - from a limiting plane
-- - to a limiting plane
-- - from one limiting plane to another.
-- The setting is provided by a flag, flag, which can be set
-- to from and/or until. The third semantic possibility above
-- is selected by showing both from and until at the same time.
