GC_MakeTrimmedCylinder Class Reference

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

DEFINE_STANDARD_ALLOC GC_MakeTrimmedCylinder (const gp_Pnt &P1, const gp_Pnt &P2, const gp_Pnt &P3)
 Make a cylindricalSurface <Cyl> from Geom
Its axis is is <P1P2> and its radius is the distance
between <P3> and <P1P2>.
The height is the distance between P1 and P2.

 GC_MakeTrimmedCylinder (const gp_Circ &Circ, const Standard_Real Height)
 Make a cylindricalSurface <Cyl> from gp by its base <Circ>.
Its axis is the normal to the plane defined bi <Circ>.
<Height> can be greater than zero or lower than zero.
In the first case the V parametric direction of the
result has the same orientation as the normal to <Circ>.
In the other case it has the opposite orientation.

 GC_MakeTrimmedCylinder (const gp_Ax1 &A1, const Standard_Real Radius, const Standard_Real Height)
 Make a cylindricalSurface <Cyl> from gp by its
axis <A1> and its radius <Radius>.
It returns NullObject if <Radius> is lower than zero.
<Height> can be greater than zero or lower than zero.
In the first case the V parametric direction of the
result has the same orientation as <A1>.
In the other case it has the opposite orientation.

 GC_MakeTrimmedCylinder (const gp_Cylinder &Cyl, const gp_Pnt &P, const Standard_Real Height)
 Make a RectangularTrimmedSurface <Cylinder> from gp by
a cylinder from gp.
It is trimmed by the point.
 GC_MakeTrimmedCylinder (const gp_Cylinder &Cyl, const gp_Pnt &P1, const gp_Pnt &P2)
 Make a RectangularTrimmedSurface <Cylinder> from gp by
a cylinder from gp.
It is trimmed by the two points <P1> and <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 cylinder.
Exceptions
StdFail_NotDone if no trimmed cylinder is constructed.

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

and the heigh <Heigh>.
<Height> can be greater than zero or lower than zero.
in the first case the limit section is in the side of
the positives V paramters of <Cyl> and in the other
side if <Heigh> is lower than zero.

  • gce_NegativeRadius if Radius is less than 0.0, or
  • gce_ConfusedPoints if the points P1 and P2 are coincident.
  • gce_ColinearPoints if the points P1, P2 and P3 are collinear.
