class MakeSegment from GC inherits Root from GC

    	--- Purpose: Implements construction algorithms for a line
    	-- segment in 3D space. The result is a Geom_TrimmedCurve curve.
    	-- A MakeSegment object provides a framework for:
    	-- -   defining the construction of the line segment,
    	-- -   implementing the construction algorithm, and
    	-- -   consulting the results. In particular, the Value
    	--   function returns the constructed line segment.
