Detailed Description

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

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.
