   Function to compute Hidden Line Removal on a :c:type:`~A3DAsmModelFile`\ . 
   
   
      10.1
   
   
   
   Call A3DComputeOrthoHLROnModelFile3(A3D_NULL_HANDLE, A3D_NULL_HANDLE, NULL, NULL, pNumberHLRRepItem, pppHLRRepItem) to release *pppHLRRepItem structure ( internal :c:type:`~A3DCrvPolyLine`\ * was not released)
   
   If ``pOptMrkRView`` is a cutting view, ``psSectionParametersData`` can be set to ``0``\ . In this case, the cutting planes within ``pOptMrkRView`` are used for the computation. Planes must to ordered and be set a profile, otherwise the function will return ``#A3D_TOOLS_INVALID_SECTION_PLANE``\ .
   
   **Parameters**
   
   
      **pModelFile**\ : Model file to work on. 
   
      **pOptMrkRView**\ : optional :c:type:`~A3DMkpView` (cut, filter and/or move entities). 
   
      **psHLRViewPlaneData**\ : define a plane as a camera with orthogonal projection. 
   
      **psHLROptionsData**\ : define options used to compute HLR. if set to NULL, default :c:struct:`~A3DHLROptionsData` value are used. 
   
      **pNumberHLRRepItem**\ : Number :c:type:`~A3DHLRRepresentationItem`\ . 
   
      **ppHLRRepItems**\ : HLR curve result grouped by :c:type:`~A3DRiRepresentationItem` entity. pppHLRRepItem is automatically allocated by A3DComputeOrthoHLROnModelFile3.
   
   
   **Returns**
   
   
      ``A3D_SUCCESS`` on success, or an error code on failure
