Some geometric entities are linked together so that they remain rigidly connected.

This connection information can be retrieved using the following functions. For more information, see `Rigid Links <https://docs.techsoft3d.com/exchange/latest/guide/advanced.html#rigid-links>`__\ section in the programming guide.

**Parameters**


   **pOwnerNode**\ : The base Product Occurrence the resulting list in built on.

   **puiNumberOfFixedSubNodes**\ : The size ``pppFixedSubNodes``

   **pppFixedSubNodes**\ : The resulting array.


**Returns**


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