◆ GCE2d_MakeSegment() [1/5]

GCE2d_MakeSegment::GCE2d_MakeSegment ( const gp_Pnt2d P1,

Make a segment of Line from the 2 points <P1> and <P2>. Status is "ConfusedPoints" if <P1> and <P2> are confused.

◆ GCE2d_MakeSegment() [2/5]

GCE2d_MakeSegment::GCE2d_MakeSegment ( const gp_Pnt2d P1,

Make a segment of Line from the point <P1> with the direction.

and ended by the projection of <P2> on the line <P1,V>. Status is "ConfusedPoints" if <P1> and <P2> are confused.

GCE2d_MakeSegment::GCE2d_MakeSegment ( const gp_Lin2d Line,
const Standard_Real  U1,
const Standard_Real  U2 
)

Make a segment of Line from the line <Line> between the two parameters U1 and U2. Status is "SameParamters" if <U1> is equal <U2>.

GCE2d_MakeSegment::GCE2d_MakeSegment ( const gp_Lin2d Line,
const gp_Pnt2d Point,
const Standard_Real  Ulast 
)

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>.

GCE2d_MakeSegment::GCE2d_MakeSegment ( const gp_Lin2d Line,
const gp_Pnt2d P1,
const gp_Pnt2d P2 
)

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.
