Detailed Description

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

• 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. The circle's parameter is the angle (Radian). The parametrization range is [0,2*PI]. The circle is a closed and periodic curve. The center of the circle is the Location point of its axis placement. The XDirection of the axis placement defines the origin of the parametrization.

Constructor & Destructor Documentation

GC_MakeCircle::GC_MakeCircle

(

const gp_Circ &

C

)

creates a circle from a non persistent circle C by its conversion.

GC_MakeCircle::GC_MakeCircle	(	const gp_Ax2 &	A2,
		const Standard_Real	Radius
	)

A2 is the local coordinates system of the circle. It is not forbidden to create a circle with Radius = 0.0 Status is "NegativeRadius" if Radius < 0.

GC_MakeCircle::GC_MakeCircle	(	const gp_Circ &	Circ,
		const Standard_Real	Dist
	)

Make a Circle from Geom <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>.

GC_MakeCircle::GC_MakeCircle	(	const gp_Circ &	Circ,
		const gp_Pnt &	Point
	)

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

GC_MakeCircle::GC_MakeCircle	(	const gp_Pnt &	P1,
		const gp_Pnt &	P2,
		const gp_Pnt &	P3
	)

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

GC_MakeCircle::GC_MakeCircle	(	const gp_Pnt &	Center,
		const gp_Dir &	Norm,
		const Standard_Real	Radius
	)

Make a Circle from Geom <TheCirc> with its center

and the normal of its plane <Norm> and its radius <Radius>.

GC_MakeCircle::GC_MakeCircle	(	const gp_Pnt &	Center,
		const gp_Pnt &	PtAxis,
		const Standard_Real	Radius
	)

Make a Circle from Geom <TheCirc> with its center

and the normal of its plane defined by the two points

and <PtAxis> and its radius <Radius>.

GC_MakeCircle::GC_MakeCircle	(	const gp_Ax1 &	Axis,
		const Standard_Real	Radius
	)

Make a Circle from Geom <TheCirc> with its center

and its radius <Radius>.
