GC_MakeTrimmedCone Class Reference

Implements construction algorithms for a trimmed
cone limited by two planes orthogonal to its axis. The
result is a Geom_RectangularTrimmedSurface surface.
A MakeTrimmedCone provides a framework for:

DEFINE_STANDARD_ALLOC 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 (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:

const
Handle_Geom_RectangularTrimmedSurface & 
Value () const
 Returns the constructed trimmed cone.
StdFail_NotDone if no trimmed cone is constructed.

const
Handle_Geom_RectangularTrimmedSurface & 
Operator () const
 operator Handle_Geom_RectangularTrimmedSurface () const

Detailed Description


Constructor & Destructor Documentation

  • 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).
