54 ---Purpose: Set Approximation Tolerance
55 -- Tol3d : Tolerance to surface approximation
56 -- Tol2d : Tolerance used to perform curve approximation
57 -- Normaly the 2d curve are approximated with a
58 -- tolerance given by the resolution on support surfaces,
59 -- but if this tolerance is too large Tol2d is used.

61 -- beetween tangents on the section law and
62 -- tangent of iso-v on approximed surface

91 ---Purpose: Build the Sweeep Surface
92 -- Transition define Transition strategy
93 -- Approx define Approximation Strategy
94 -- - GeomFill_Section : The composed Function Location X Section
95 -- is directly approximed.
96 -- - GeomFill_Location : The location law is approximed, and the
97 -- SweepSurface is bulid algebric composition
98 -- of approximed location law and section law
99 -- This option is Ok, if Section.Surface() methode
100 -- is effective.
101 -- Continuity : The continuity in v waiting on the surface
102 -- Degmax : The maximum degree in v requiered on the surface
103 -- Segmax : The maximum number of span in v requiered on
104 -- the surface.
