Detailed Description

Implements construction algorithms for parabola arcs in 3D space. The result is a Geom_TrimmedCurve. A MakeArcOfParabola object provides a framework for:

• defining the construction of the arc of parabola,
• implementing the construction algorithm, and
• consulting the results. In particular, the Value function returns the constructed arc of parabola.
