How to use the Isometric Cleanup When the Output Format is DWG/PDF article

In the article it gives the dwg output as 2D only.

Since running OPIM version 08.11.11.285 with AutoPlant Modeler version 08.11.13.211 and update to .245 we have been getting a 3D dwg ouput as well as the 2D. Can this be turned off as we do not require it.

Best Regards
