3D PDF PRINTING

Hello,

I am fairly new to the Bentley software, presently using Microstation V8i SS2.

I printed to a 3d pdf by toggling the Bentley driver in the print dialog, selecting the Print to 3D, but when I open the pdf in Adobe Acrobat Pro, I do not get the 3d tool bar to allow rotating or sectioning the pdf view.  Is there a toggle I am missing or some step in my workflow?
