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.

---Purpose: Make a segment of Line from the 2 points <P1> and <P2>.
-- It returns NullObject if <P1> and <P2> are confused.

---Purpose: Make a segment of Line from the line <Line1>
-- between the two parameters U1 and U2.
-- It returns NullObject if <U1> is equal <U2>.

---Purpose: Make a segment of Line from the line <Line1>
