class MakeCone from BRepPrimAPI inherits MakeOneAxis from BRepPrimAPI
---Purpose: Describes functions to build cones or portions of cones.
-- A MakeCone object provides a framework for:
-- - defining the construction of a cone,
-- - implementing the construction algorithm, and
-- - consulting the result.

DomainError from Standard; -- if H <= Precision::Confusion()
---Purpose: Constructs a cone, or a portion of a cone, of height H,
-- and radius R1 in the plane z = 0 and R2 in the plane
-- z = H. The result is a sharp cone if R1 or R2 is equal to 0.
-- The cone is constructed about the "Z Axis" of either:
-- - the global coordinate system, or
-- - the local coordinate system Axes.
-- It is limited in these coordinate systems as follows:
-- - in the v parametric direction (the Z coordinate), by
-- the two parameter values 0 and H,
-- - and in the u parametric direction (defined by the
-- angle of rotation around the Z axis), in the case of a
-- portion of a cone, by the two parameter values 0 and
-- angle. Angle is given in radians.
-- The resulting shape is composed of:
-- - a lateral conical face
-- - two planar faces in the planes z = 0 and z = H,
-- or only one planar face in one of these two planes if a
-- radius value is null (in the case of a complete cone,
-- these faces are circles), and
-- - and in the case of a portion of a cone, two planar
-- faces to close the shape. (either two parallelograms or
-- two triangles, in the planes u = 0 and u = angle).
-- Exceptions
-- Standard_DomainError if:
-- - H is less than or equal to Precision::Confusion(), or
-- - the half-angle at the apex of the cone, defined by
-- R1, R2 and H, is less than Precision::Confusion()/H, or greater than
-- (Pi/2)-Precision::Confusion()/H.f
