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.

GCE2d_MakeArcOfCircle::GCE2d_MakeArcOfCircle	(	const gp_Circ2d &	Circ,
		const Standard_Real	Alpha1,
		const Standard_Real	Alpha2,
		const Standard_Boolean	Sense = Standard_True
	)

Makes an arc of circle (TrimmedCurve from Geom2d) from
a circle between two parameters Alpha1 and Alpha2.
The two parameters are angles. The parameters are
in radians.

		const Standard_Boolean	Sense = Standard_True
	)

Makes an arc of circle (TrimmedCurve from Geom2d) from
a circle between point.
