Detailed Description
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.
Constructor & Destructor Documentation
◆ GCE2d_MakeSegment() [1/5]
Make a segment of Line from the 2 points <P1> and <P2>. Status is "ConfusedPoints" if <P1> and <P2> are confused.

| GCE2d_MakeSegment::GCE2d_MakeSegment | ( | const gp_Pnt2d & | P1, |
| const gp_Dir2d & | V, | ||
| const gp_Pnt2d & | P2 | ||
| ) |
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 "SameParameters" if <U1> is equal <U2>.
◆ GCE2d_MakeSegment() [4/5]
| 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() [5/5]
| GCE2d_MakeSegment::GCE2d_MakeSegment | ( | const gp_Lin2d & | Line, |
| const gp_Pnt2d & | P1, | ||

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.
