GC_MakeArcOfCircle Class Reference

Implements construction algorithms for an
arc of circle in 3D space. The result is a Geom_TrimmedCurve curve.
A MakeArcOfCircle object provides a framework for:

DEFINE_STANDARD_ALLOC GC_MakeArcOfCircle (const gp_Circ &Circ, const Standard_Real Alpha1, const Standard_Real Alpha2, const Standard_Boolean Sense)
 Make an arc of circle (TrimmedCurve from Geom) from
a circle between two angles Alpha1 and Alpha2
given in radiians.

 GC_MakeArcOfCircle (const gp_Circ &Circ, const gp_Pnt &P, const Standard_Real Alpha, const Standard_Boolean Sense)
 Make an arc of circle (TrimmedCurve from Geom) from
a circle between point.
 GC_MakeArcOfCircle (const gp_Circ &Circ, const gp_Pnt &P1, const gp_Pnt &P2, const Standard_Boolean Sense)
 Make an arc of circle (TrimmedCurve from Geom) from
a circle between two points P1 and P2.

 GC_MakeArcOfCircle (const gp_Pnt &P1, const gp_Pnt &P2, const gp_Pnt &P3)
 Make an arc of circle (TrimmedCurve from Geom) from
three points P1,P2,P3 between two points P1 and P2.

 GC_MakeArcOfCircle (const gp_Pnt &P1, const gp_Vec &V, const gp_Pnt &P2)
 Make an arc of circle (TrimmedCurve from Geom) from
two points P1,P2 and the tangente to the solution at
the point P1.
The orientation of the arc is:

const Handle_Geom_TrimmedCurve & Value () const
 Returns the constructed arc of circle.
Exceptions StdFail_NotDone if no arc of circle is constructed.

Detailed Description


Constructor & Destructor Documentation

and the angle Alpha
given in radians.

  • the sense determined by the order of the points P1, P3 and P2;
  • the sense defined by the vector V; or
  • for other syntaxes:
    • the sense of Circ if Sense is true, or
    • the opposite sense if Sense is false.
      Note: Alpha1, Alpha2 and Alpha are angle values, given in radians.
      Warning
      If an error occurs (that is, when IsDone returns
      false), the Status function returns:
  • gce_ConfusedPoints if:
    • any 2 of the 3 points P1, P2 and P3 are coincident, or
    • P1 and P2 are coincident; or
  • gce_IntersectionError if:
    • P1, P2 and P3 are collinear and not coincident, or
    • the vector defined by the points P1 and
      P2 is collinear with the vector V.
