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> <br>
      from a cone and trimmed by two points P1 and P2 and <br>
      the two radius <R1> and <R2> of the sections passing <br>
      through <P1> an <P2>. <br>

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).
