class MakeSegment from GCE2d inherits Root from GCE2d
---Purpose: Implements construction algorithms for a line
-- segment in the plane. The result is a
-- Geom2d_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.

Create(P1, P2 : Pnt2d from gp ) returns MakeSegment;
---Purpose: Make a segment of Line from the 2 points <P1> and <P2>.
-- Status is "ConfusedPoints" if <P1> and <P2> are confused.
Create(P1 : Pnt2d from gp ;
V : Dir2d from gp ;
P2 : Pnt2d from gp ) returns MakeSegment;
---Purpose: Make a segment of Line from the point <P1> with
-- the direction <P> and ended by the projection of
-- <P2> on the line <P1,V>.
-- Status is "ConfusedPoints" if <P1> and <P2> are confused.
Create(Line : Lin2d from gp ;
U1, U2 : Real from Standard ) returns MakeSegment;
---Purpose: Make a segment of Line from the line <Line>
-- between the two parameters U1 and U2.
-- Status is "SameParamters" if <U1> is equal <U2>.
Create(Line : Lin2d from gp ;
Point : Pnt2d from gp ;
Ulast : Real from Standard ) returns MakeSegment;
---Purpose: Make a segment of Line from the line <Line>
-- between the point <Point> and the parameter Ulast.
-- It returns NullObject if <U1> is equal <U2>.
Create(Line : Lin2d from gp ;
P1 : Pnt2d from gp ;
P2 : Pnt2d from gp ) returns MakeSegment;
---Purpose: Make a segment of Line from the line <Line>
-- between the two points <P1> and <P2>.
-- It returns NullObject if <P1> and <P2> are confused.
-- Warning
-- If the points which limit the segment are coincident
-- for given points or for the projection of given points
-- on the line which supports the line segment (that is,
-- when IsDone returns false), the Status function
-- returns gce_ConfusedPoints. This warning only
-- concerns the first two constructors.
