Detailed Description

Implements construction algorithms for an arc of circle in the plane. The result is a Geom2d_TrimmedCurve curve. A MakeArcOfCircle object provides a framework for:

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