The PADS Collaborator option supports the Pro STEP format. There is a good on-demand webinar you can take a look at at http://www.mentor.com/products/pcb-system-design/events/how-effective-ecad---mcad-collaboration-reduces-costs-and-achieves-first-to-market-success
There is also a short video snippet on the PADS YouTube channel at http://www.youtube.com/PADSPCBDesign

thank you for the links.
I watched the video and understood anything about the ProStep interface.
What I need, though, is the 3D file in STEP format of the whole board: PCB, components, vias, traces and holes.
Is there any way to get the 3D file of the board?
