##########
Model File
##########

Reads and writes a physical file containing a PRC model file; and creates and accesses model file entities.

The :c:type:`~A3DAsmModelFile`\ is the root entity of the PRC data. It is the starting point for parsing a PRC file. It is also one of the arguments used to create a 3D annotation within a PDF document.

Entity type is :c:enumerator:`~kA3DTypeAsmModelFile`\ .

**Parameters**


   **pModelFile**\ : A reference to the model file, which is created by invoking ``A3DAsmModelFileLoadFromFile``

   **pData**\ : A reference to the :c:struct:`~A3DAsmModelFileData`\ structure in which the library stores the model file data


**Returns**


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