◆ GC_MakeTrimmedCone() [1/2]

GC_MakeTrimmedCone::GC_MakeTrimmedCone ( const gp_Pnt P1,
const gp_Pnt P2,
const gp_Pnt P3,
const gp_Pnt P4 
)

Make a RectangularTrimmedSurface <TheCone> from Geom It is trimmed by P3 and P4. Its axis is <P1P2> and the radius of its base is the distance between <P3> and <P1P2>. The distance between <P4> and <P1P2> is the radius of the section passing through <P4>. An error iss raised if <P1>,<P2>,<P3>,<P4> are colinear or if <P3P4> is perpendicular to <P1P2> or <P3P4> is colinear to <P1P2>.

◆ GC_MakeTrimmedCone() [2/2]

GC_MakeTrimmedCone::GC_MakeTrimmedCone ( const gp_Pnt P1,
const gp_Pnt P2,
const Standard_Real  R1,
const Standard_Real  R2 
)

Make a RectangularTrimmedSurface from Geom <TheCone> from a cone and trimmed by two points P1 and P2 and the two radius <R1> and <R2> of the sections passing through <P1> an <P2>. Warning If an error occurs (that is, when IsDone returns false), the Status function returns:

  • gce_ConfusedPoints if points P1 and P2, or P3 and P4, are coincident;
  • gce_NullAngle if:
  • the lines joining P1 to P2 and P3 to P4 are parallel, or
  • R1 and R2 are equal (i.e. their difference is less than gp::Resolution());
  • gce_NullRadius if:
  • the line joining P1 to P2 is perpendicular to the line joining P3 to P4, or
  • the points P1, P2, P3 and P4 are collinear;
  • gce_NegativeRadius if R1 or R2 is negative; or
  • gce_NullAxis if points P1 and P2 are coincident (2nd syntax only).
