There is a third-party software that can do this. It is a plug-in for AutoCAD. See the link below.
Or..... Another way of potentailly doing it.
You can get the data into AutoCAD in a roundabout way, Aveva have a separate conversion software program called Explant which exports PDMS models into Microstation 3D Dgn format, from Microstation you can then Export the model to DWG/DXF, ACIS,SAT and Parasolid.
You would need access to PDMS, Explant and Microstation.
Not much good if you only have AutoCAD though!!
