class MakeArcOfParabola from GC inherits Root from GC
    	---Purpose: Implements construction algorithms for an arc
    	-- of parabola in 3D space. The result is a Geom_TrimmedCurve curve.
    	-- A MakeArcOfParabola object provides a framework for:
    	-- -   defining the construction of the arc of parabola,
    	-- -   implementing the construction algorithm, and
    	-- -   consulting the results. In particular, the
    	--   Value function returns the constructed arc of parabola.
