Detailed Description

This class implements the following algorithms used
to create Cirlec from Geom2d.

• Create a Circle parallel to another and passing
  though a point.
  
• Create a Circle parallel to another at the distance
  Dist.
  
• Create a Circle passing through 3 points.
  
• Create a Circle with its center and the normal of its
  plane and its radius.
  
• Create a Circle with its axis and radius.
  

Constructor & Destructor Documentation

GCE2d_MakeCircle::GCE2d_MakeCircle

(

const gp_Circ2d &

C

)

creates a circle from a non persistent one.

GCE2d_MakeCircle::GCE2d_MakeCircle	(	const gp_Ax2d &	A,
		const Standard_Real	Radius,
		const Standard_Boolean	Sense = Standard_True
	)

A is the "XAxis" of the circle which defines the origin
of parametrization.
It is not forbidden to create a circle with Radius = 0.0
The status is "NegativeRadius" if Radius < 0.

GCE2d_MakeCircle::GCE2d_MakeCircle	(	const gp_Ax22d &	A,
		const Standard_Real	Radius
	)

A is the local coordinate system of the circle which defines
the origin of parametrization.
It is not forbidden to create a circle with Radius = 0.0
The status is "NegativeRadius" if Radius < 0.

GCE2d_MakeCircle::GCE2d_MakeCircle	(	const gp_Circ2d &	Circ,
		const Standard_Real	Dist
	)

Make a Circle from Geom2d <TheCirc> parallel to another
Circ <Circ> with a distance <Dist>.
If Dist is greater than zero the result is enclosing
the circle <Circ>, else the result is enclosed by the
circle <Circ>.

GCE2d_MakeCircle::GCE2d_MakeCircle	(	const gp_Circ2d &	Circ,
		const gp_Pnt2d &	Point
	)

Make a Circle from Geom2d <TheCirc> parallel to another
Circ <Circ> and passing through a Pnt <Point>.

GCE2d_MakeCircle::GCE2d_MakeCircle	(	const gp_Pnt2d &	P1,
		const gp_Pnt2d &	P2,
		const gp_Pnt2d &	P3
	)

Make a Circ from gp <TheCirc> passing through 3
Pnt2d <P1>,<P2>,<P3>.

GCE2d_MakeCircle::GCE2d_MakeCircle	(	const gp_Pnt2d &	P,
		const Standard_Real	Radius,
		const Standard_Boolean	Sense = Standard_True
	)

Make a Circ from geom2d <TheCirc> by its center an radius.

GCE2d_MakeCircle::GCE2d_MakeCircle	(	const gp_Pnt2d &	Center,
		const gp_Pnt2d &	Point,
		const Standard_Boolean	Sense = Standard_True
	)

 Makes a Circle from geom2d <TheCirc> with its center <br>
      <Center> and a point giving the radius. <br>
      If Sense is true the local coordinate system of <br>
      the solution is direct and non direct in the other case. <br>

Warning
The MakeCircle class does not prevent the
construction of a circle with a null radius.
If an error occurs (that is, when IsDone returns
false), the Status function returns:

• gce_NegativeRadius if Radius is less than 0.0, or
  
• gce_IntersectionError if points P1, P2 and P3
  are collinear and the three are not coincident.
