class MakeTrimmedCone from GC inherits Root from GC

    --- Purpose: 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.

    --          The distance between <P4> and <P1P2> is the radius of

    -- 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).
