Detailed Description

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.

Constructor & Destructor Documentation

BRepPrimAPI_MakeCone() [1/4]

BRepPrimAPI_MakeCone::BRepPrimAPI_MakeCone	(	const Standard_Real	R1,
		const Standard_Real	R2,
		const Standard_Real	H
	)

Make a cone.

Parameters

R1	[in] cone bottom radius, may be null (z = 0)
R2	[in] cone top radius, may be null (z = H)
H	[in] cone height

BRepPrimAPI_MakeCone() [2/4]

BRepPrimAPI_MakeCone::BRepPrimAPI_MakeCone	(	const Standard_Real	R1,
		const Standard_Real	R2,
		const Standard_Real	H,
		const Standard_Real	angle
	)

Make a cone.

Parameters

R1	[in] cone bottom radius, may be null (z = 0)
R2	[in] cone top radius, may be null (z = H)
H	[in] cone height
angle	[in] angle to create a part cone

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.

Parameters

axes	[in] coordinate system for the construction of the cone
R1	[in] cone bottom radius, may be null (z = 0)
R2	[in] cone top radius, may be null (z = H)
H	[in] cone height

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
