Detailed Description

Creates B-Rep solid primitives.

The ModelAlgo_TopoPrimitives class provides static methods to construct 3D topological solid primitives. Created primitives can be either complete or truncated. For instance, a sphere can be created either as a full sphere or bounded by its angles along U and V directions.

The following table demonstrates supported primitives:

CreateBox()	Box
CreateSphere()	Sphere td
CreateCylinder()	Sphere td
CreateCone()	Sphere td
CreateTorus()	Sphere td

static

Creates a cone.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Creates a cone located in the origin of a local coordinate system theAxis. Parametrization is along the axes of theAxis and use of parameters is the same as in the first CreateCone() overload.

CreateCone() [2/2]

ModelData_Solid cadex::ModelAlgo_TopoPrimitives::CreateCone ( double  theRadius1, double  theRadius2, double  theHeight, double  theAngle = 2 * M_PI  )

static

Creates a cone.

Creates a cone located in the origin of a global coordinate system, with theRadius1 and theRadius2, theHeight and parametrized along axes of the global coordinate system.

If theAngle is specified then it defines trimming the cone along the angle of rotation. theAngle must be in the range (0, 2 * PI].

A full cone is created if theAngle use its default value.

static

Creates a sphere.

Creates a sphere located in the origin of a global coordinate system, with theRadius and parametrized along axes of the global coordinate system.

If the parameters theU, theVmin and theVmax are defined they define trimming the sphere as follows:

• theU limits the sphere along the meridian angle. theU must be in the range (0, 2 * PI];
• theVmin and theVmax limit the sphere along the parallels. theVmin must be in the range [-PI / 2, theVmax) and theVmax must be in the range (theVmin, PI / 2];

A full sphere is created if the angular parameters use their default values.

If the parameters theU, theVmin and theVmax are defined they define trimming the torus as follows:

• theU limits the torus along the rotation angle along the Z axis with major radius. theU must be in the range (0, 2 * PI];
• theVmin and theVmax limit the torus along the rotation with minor raidus. theVmin must be in the range [0, theVmax) and theVmax must be in the range (theVmin, 2 * PI];

A full sphere is created if the angular parameters use their default values.
