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() [1/8]

GCE2d_MakeCircle::GCE2d_MakeCircle ( const gp_Circ2d & C )

creates a circle from a non persistent one.

◆ GCE2d_MakeCircle() [2/8]

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() [3/8]

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() [4/8]

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() [5/8]

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() [6/8]

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() [7/8]

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() [8/8]

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

and a point giving the radius. If Sense is true the local coordinate system of the solution is direct and non direct in the other case. 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.

Member Function Documentation

◆ operator const Handle< Geom2d_Circle > &()

GCE2d_MakeCircle::operator const Handle< Geom2d_Circle > & ( ) const

inline

◆ Value()

const Handle< Geom2d_Circle >& GCE2d_MakeCircle::Value ( ) const

Returns the constructed circle. Exceptions StdFail_NotDone if no circle is constructed.
