 BRepPrimAPI_MakeCone (const Standard_Real R1, const Standard_Real R2, const Standard_Real H)
 Make a cone of height H radius R1 in the plane z =
0, R2 in the plane Z = H. R1 and R2 may be null.

 BRepPrimAPI_MakeCone (const Standard_Real R1, const Standard_Real R2, const Standard_Real H, const Standard_Real angle)
 Make a cone of height H radius R1 in the plane z =
0, R2 in the plane Z = H. R1 and R2 may be null.
Take a section of <angle>

 BRepPrimAPI_MakeCone (const gp_Ax2 &Axes, const Standard_Real R1, const Standard_Real R2, const Standard_Real H)
 Make a cone of height H radius R1 in the plane z =
0, R2 in the plane Z = H. R1 and R2 may be null.

 BRepPrimAPI_MakeCone (const gp_Ax2 &Axes, const Standard_Real R1, const Standard_Real R2, const Standard_Real H, const Standard_Real angle)
 Make a cone of height H radius R1 in the plane z =
0, R2 in the plane Z = H. R1 and R2 may be null.
Take a section of <angle>
//! 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:

Standard_Address OneAxis ()
 Returns the algorithm.

BRepPrim_ConeCone ()
 Returns the algorithm.

  • 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
