Detailed Description

This class implements construction algorithms for arcs of circles in the plane. The result is a Geom2d_TrimmedCurve. A GC_MakeArcOfCircle2d object provides a framework for:

• defining the construction parameters;
• running the construction algorithm;
• querying the construction status and the resulting arc via Value().

  Note

  Angular parameters are expressed in radians.
