Hi,
I have exactly the same problem.
When I´m in the “fast draft mode” i can see my 3D object normaly.
As I change it to Final Quality it disappeares…
The strange thing is that it worked when I got my MAC.
But for some how the function got damage and I don´t no when and why it happend.
My Mac is running with a Quadro 4000 under OSX 10.8.3
I would be really happy for any kind of help
