## Detailed Description

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:

• defining the construction of the trimmed cone,
• implementing the construction algorithm, and
• consulting the results. In particular, the Value function returns the constructed trimmed cone.

## Constructor & Destructor Documentation

 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::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).

 const Handle< Geom_RectangularTrimmedSurface >& GC_MakeTrimmedCone::Value ( ) const

Returns the constructed trimmed cone. StdFail_NotDone if no trimmed cone is constructed.
