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::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() [3/4]

BRepPrimAPI_MakeCone::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() [4/4]

BRepPrimAPI_MakeCone::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:

  • 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
