Curve On Surface

Detailed Description

group a3d_crvonsurf

Entity type is kA3DTypeCrvOnSurf.

Version
2.0

For the canonical definition of this curve, see the “SerializeTransformationCurve” section of the .

Note

A3DParameterizationData must have A3DParameterizationData::m_dCoeffA set to 1, A3DParameterizationData::m_dCoeffB set to 0 and an A3DIntervalData identical to the one of A3DCrvOnSurfData::m_pUVCurve.

Note

A3DMiscCartesianTransformationData should correspond to identity transformation.

Note

A3DCrvOnSurfData::m_pUVCurve must be a curve of type kA3DTypeCrvLine or kA3DTypeCrvNurbs.
