Syntax
C++
void getProjClosestPointTo(const OdGePoint3d& point, const OdGeVector3d& projectDirection, OdGePointOnCurve3d& pntOnCrv, const OdGeTol& tol = OdGeContext::gTol) const;
Parameters
Parameters 
Description 
const OdGePoint3d& point 
[in] Any 3D point.  
const OdGeVector3d& projectDirection 
[in] Projection Direction.  
OdGePointOnCurve3d& pntOnCrv 
[out] Receives the closest point on this curve.  
const OdGeTol& tol = OdGeContext::gTol 
[in] Geometric tolerance. 
Description

Returns the point on this curve closest to the specified point when this curve is projected in the specified direction. 

 

Remarks

By default this function throws the exception "not Implemented". Should be implemented in derived classes.
