This happens to me too, additionally if I zoom in or out or pan left or right a whole bunch, sometimes I can find the tiny 3d version of my plan. But then zooming gives me a perspective looking straight on at the facade of the exterior wall, and left and right moves just like I was walking left and right, looking at the facade. I want to go back to the other perspective, where the plan turns on a ‘wheel’ so I can see inside the spaces. I don’t have a drop down menu under “3D” like I do under 2D and like in the tutorials. I’m on a laptop (new) with chrome and flash is all good. Any suggestions for this as well?
Cheers
