class MakeTorus from BRepPrimAPI  inherits MakeOneAxis from BRepPrimAPI

	---Purpose: Describes functions to build tori or portions of tori.
    	-- A MakeTorus object provides a framework for:
    	-- -   defining the construction of a torus,
    	-- -   implementing the construction algorithm, and
    	-- -   consulting the result.

    	---Purpose: For all algorithms The resulting shape is composed of
    	--   -      a lateral toroidal face,
    	--   -      two conical faces (defined  by the equation v = angle1 and
    	--      v = angle2) if the sphere is truncated in the v parametric
    	--      direction (they may be cylindrical faces in some
    	--      particular conditions), and in case of a portion
    	--      of torus, two planar faces to close the shape.(in the planes
    	--      u = 0 and u = angle).
    	-- Notes:
    	--   -      The u parameter corresponds to a rotation angle around the Z axis.
    	--   -      The circle whose radius is equal to the minor radius,
    	--      located in the plane defined by the X axis and the Z axis,
    	--      centered on the X axis, on its positive side, and positioned
    	--      at a distance from the origin equal to the major radius, is
    	--      the reference circle of the torus. The rotation around an
    	--      axis parallel to the Y axis and passing through the center
    	--      of the reference circle gives the v parameter on the
    	--      reference circle. The X axis gives the origin of the v
    	-- parameter. Near 0, as v increases, the Z coordinate decreases.
