## 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::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::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::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::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::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::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::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::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.
