-- =================================
-- Methodes Set
-- =================================
---Purpose: Set an sweep's mode
-- If no mode are setted, the mode use in MakePipe is used
---See Also: GeomFill_IsCorrectedFrenet
Set(me : mutable; Frenet : Boolean = Standard_False);
---Purpose: Set an Frenet or an CorrectedFrenet trihedron
-- to perform the sweeping
---Level: Public
---See Also:GeomFill_IsCorrectedFrenet
Set(me : mutable; Axe : Ax2 from gp);
---Purpose: Set an fixed trihedron to perform the sweeping
-- all sections will be parallel.
---Level: Public
---See Also: GeomFill_IsFixed
Set(me : mutable; BiNormal : Dir from gp);
---Purpose: Set an fixed BiNormal direction to perform
-- the sweeping
---Level: Public
---See Also: GeomFill_IsConstantNormal
Set(me : mutable; SpineSupport : Shape from TopoDS)
---Purpose: Set support to the spine to define the BiNormal
-- at the spine, like the normal the surfaces.
-- Warning: To be effective, Each edge of the <spine> must
-- have an representaion on one face of<SpineSupport>
---Level: Public
---See Also: GeomFill_IsDarboux

---Purpose: Set an auxiliary spine to define the Normal
-- For each Point of the Spine P, an Point Q is evalued
-- on <AuxiliarySpine>
-- If <CurvilinearEquivalence>
-- Q split <AuxiliarySpine> with the same length ratio
-- than P split <Spline>.
-- Else the plan define by P and the tangent to the <Spine>
-- intersect <AuxiliarySpine> in Q.
-- If <KeepContact> the Normal is defined to assume like the sweeped
-- section is in contact to the <AuxiliarySpine>
-- Else the Normal is defined by the vector PQ.

-- =================================
-- Methodes to define section(s)
-- =================================
---Purpose: Give section to sweep.
-- Possibilities are :
-- - Give one or sevral profile
-- - Give one profile and an homotetic law.
-- - Automatic compute of correspondance beetween profile, and section
-- on the sweeped shape
-- - correspondance beetween profile, and section on the sweeped shape
-- defined by a vertex of the spine
-- -"WithCorrection" The profile is rotated to have a Normal --
-- parallel to the trihedron's normal and have tangent
-- perpendicular to the trihedron's tangent.
