Detailed Description

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

DEFINE_STANDARD_ALLOC GCE2d_MakeArcOfEllipse::GCE2d_MakeArcOfEllipse	(	const gp_Elips2d &	Elips,
		const Standard_Real	Alpha1,
		const Standard_Real	Alpha2,
		const Standard_Boolean	Sense = Standard_True
	)

		const gp_Pnt2d &	P,
		const Standard_Real	Alpha,
		const Standard_Boolean	Sense = Standard_True
	)

and the parameter
Alpha.

GCE2d_MakeArcOfEllipse::GCE2d_MakeArcOfEllipse	(	const gp_Elips2d &	Elips,
		const gp_Pnt2d &	P1,
		const gp_Pnt2d &	P2,
		const Standard_Boolean	Sense = Standard_True
	)

• the trigonometric sense if Sense is not defined or
  is true (default value), or
  
• the opposite sense if Sense is false.
  
• Alpha1, Alpha2 and Alpha are angle values, given in radians.
  
• IsDone always returns true.
