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.

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>.

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).
