Detailed Description

This class implements the following algorithms used to create Circ from gp.

• Create a Circ coaxial to another and passing though a point.
• Create a Circ coaxial to another at the distance Dist.
• Create a Circ passing through 3 points.
• Create a Circ with its center and the normal of its plane and its radius.
• Create a Circ with its center and its plane and its radius.
• Create a Circ with its axis and radius.
• Create a Circ with two points giving its axis and its radius.
• Create a Circ with is Ax2 and its Radius.

Constructor & Destructor Documentation

gce_MakeCirc() [1/8]

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

A2 locates the circle and gives its orientation in 3D space. Warnings : It is not forbidden to create a circle with Radius = 0.0 The status is "NegativeRadius" if Radius < 0.0.

gce_MakeCirc() [2/8]

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

Makes a Circ from gp <TheCirc> coaxial to another Circ <Circ> at a distance <Dist>. If Dist is greater than zero the result is encloses the circle <Circ>, else the result is enclosed by the circle <Circ>.

gce_MakeCirc() [3/8]

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

Makes a Circ from gp <TheCirc> coaxial to another Circ <Circ> and passing through a Pnt2d <Point>.

gce_MakeCirc() [4/8]

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

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

gce_MakeCirc() [5/8]

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

Makes a Circ from gp <TheCirc> with its center

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

gce_MakeCirc() [6/8]

gce_MakeCirc::gce_MakeCirc	(	const gp_Pnt &	Center,
		const gp_Pln &	Plane,
		const Standard_Real	Radius )

Makes a Circ from gp <TheCirc> with its center

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

gce_MakeCirc() [7/8]

gce_MakeCirc::gce_MakeCirc	(	const gp_Pnt &	Center,
		const gp_Pnt &	Ptaxis,
		const Standard_Real	Radius )

Makes a Circ from gp <TheCirc> with its center

and a point <Ptaxis> giving the normal of its plane <Plane> and its radius <Radius>.

gce_MakeCirc() [8/8]

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

Makes a Circ from gp <TheCirc> with its center

and its radius <Radius>. Warning The MakeCirc 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_Negative Radius if:
• Radius is less than 0.0, or
• Dist is less than 0.0 and the absolute value of Dist is greater than the radius of Circ;
• gce_IntersectionError if the points P1, P2 and P3 are collinear, and the three are not coincident;
• gce_ConfusedPoints if two of the three points P1, P2 and P3 are coincident; or
• gce_NullAxis if Center and Ptaxis are coincident.
