Constructor & Destructor Documentation

◆ GC_MakeArcOfCircle() [1/5]

GC_MakeArcOfCircle::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() [2/5]

GC_MakeArcOfCircle::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.

and the angle Alpha given in radians.

◆ GC_MakeArcOfCircle() [3/5]

GC_MakeArcOfCircle::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() [4/5]

GC_MakeArcOfCircle::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() [5/5]

GC_MakeArcOfCircle::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:

  • 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.
