A3DCurveLength(const A3DCrvBase *pCrv, const A3DIntervalData *pOptInterval, A3DDouble *pdLength) A3DStatusA3DCurveLength(constA3DCrvBase* pCrv, constA3DIntervalData* pOptInterval,A3DDouble* pdLength)Function to compute the length of a curve (optionally restricted to an interval)
Parameters
pCrv: The curve:
A3DCrvBase.pOptInterval: The interval of restriction of the curve (if NULL, the natural interval of the curve will be used).
pdLength: The length of the curve.
Returns
A3D_SUCCESSon success, or an error code on failure
