   6.1



Compute section functions for model file. 


   :c:func:`~A3DComputePlanarSectionOnRepresentationItem` 



   :c:func:`~A3DComputePlanarSectionOnModelFile` 


**Parameters**


   **pRiBrepModel**\ : B-rep models. 

   **psSectionParametersData**\ : Parameters of the planar section. 

   **ppRISectionResults**\ : Array of section curves. ppRISectionResults is automatically allocated by A3DComputePlanarSectionOnRepresentationItem. It has to be freed with a call to A3DComputePlanarSectionOnRepresentationItem(A3D_NULL_HANDLE, psSectionParametersData, ppRISectionCurvesis). 


**Returns**


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