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