DEFINE_STANDARD_ALLOC GCE2d_MakeCircle (const gp_Circ2d &C)
 creates a circle from a non persistent one.

 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 (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 (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 (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 (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 (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 (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:

const Handle_Geom2d_Circle & Value () const
 Returns the constructed circle.
Exceptions StdFail_NotDone if no circle is constructed.

const Handle_Geom2d_Circle & Operator () const
 operator Handle_Geom2d_Circle () const

Detailed Description


Constructor & Destructor Documentation

  • 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.
