Parameters 

Description 

const OdGeCurve3d& geCurve 

[in] reference to an OdGeCurve3d.  

OdGeVector3d * normal = NULL 

[in] Optional normal vector. If this parameter is supplied then it must be a valid vector that is perpendicular to the input geCurve, and this vector will become the normal vector of the output pDbCurve. If this parameter is not supplied, then this function will compute the normal vector itself.  

const OdGeTol& tol = OdGeContext::gTol 

[in] Optional tolerance.
