Circular Curve

2.0

Entity type is kA3DTypeCrvCircle.

The canonical form is defined with an A3DMiscCartesianTransformationData, its origin being the center of the circle and its vector X being the axis corresponding to zero parameter. The implicit parameterization is an angle expressed as radians in the range [0, 2PI].

A3DParameterizationData lets you specify reparameterization and trim.

  • To specify the interval in radians, set m_dCoeffA to 1.0 and m_dCoeffB to 0.0. These parameter values specify an identity conversion.
  • To specify the interval in degrees, set m_dCoeffA to PI/180 and m_dCoeffB to 0.0. m_dCoeffA is the ratio of radians to degrees.

Here are parameterization examples:

Returns

A3D_SUCCESS on success, or an error code on failure
