3D projection not working?

[Anonymous]

I recently upgraded to AC 12 from 11, and now when I begin a new project, or review an older one, I can not see the structure in 3D projection. The structures look fine in 2D but once I switch to 3D they can no longer be seen, except when I select the entire screen then I can see the green outline of my structures walls but otherwise the screen is blank. If anyone has any ideas about what might be going on I would love to hear them. It almost seems like the model data is getting lost?

do all the structure disappear for all the projects no matter they are created in AC11 or AC12?

p.s. write down your software version, OS, computer config. in your signature would be much helpful

It could be a graphics card driver problem because if they are selected they are visible if they are not selected they are not.
This tells me that your camera position is correct so elements should be visible in 3D.
Try the latest drivers for you card.
Also check if the elements are visible with the Internal 3D Engine (I am guessing you are now using the OpenGL Engine in 3D).

Thanks for the ideas, I have installed new graphics card drivers and the 3D projections can now be seen, in both the Internal 3D and OpenGL engines (previously they were not visible in either). I have also added my system information in case it helps anyone else.
