32//! Implements construction algorithms for an arc
33//! of parabola in 3D space. The result is a Geom_TrimmedCurve curve.
34//! A MakeArcOfParabola object provides a framework for:
35//! - defining the construction of the arc of parabola,
36//! - implementing the construction algorithm, and
37//! - consulting the results. In particular, the
38//! Value function returns the constructed arc of parabola.
