# A3DCrvProjectPoint

A3DStatus `A3DCrvProjectPoint`(const A3DCrvBase *pCrv, const A3DVector3dData *pPointToProject, A3DUns32 *puiNbSolutions, A3DDouble **ppdSolutionParameter, A3DDouble **ppdSolutionDistance)
  `A3DStatus` A3DCrvProjectPoint(const `A3DCrvBase`* pCrv, const `A3DVector3dData`* pPointToProject, `A3DUns32`* puiNbSolutions, `A3DDouble`** ppdSolutionParameter, `A3DDouble`** ppdSolutionDistance)

  This function projects a point on a curve.

  Parameters

  > pCrv: The input curve.

  > pPointToProject: The input point to project on curve.

  > puiNbSolutions: The number of returned solutions.

  > ppdSolutionParameter: Array of parameters on the curve.

  > ppdSolutionDistance: Array of spatial distances between pPointToProject and the solution (on the curve).

  Returns

  > `A3D_SUCCESS`on success, or an error code on failure
