All,

I am working on a model in v3.61 and seem to have lost the 3D rendering
of the building. When I try to right click on the otherwise black
background to "Reset Camera", it pops up a list of all the zones in the
building. I've run the simulation (because doing that has worked in the
past to restore the 3D rendering), unchecked more than half of the
components on the 3D View Details tab, tried opening the file in v3.60,
tried opening the file on another machine, etc. Nothing.

Has anyone else encountered this and what did you do to fix the issue?
Any help is appreciated.
