Alt Rotate Not Working

izygirl1d  Does your alt key always work in other circumstances?  What about using the other alt key, if your keyboard has two?  And does it help to play in windowed mode, and/or to switch to the Sims 4 camera and back to the Sims 3 camera before starting to build?

This has sometimes been a bit wonky for me, in that the objects don't always rotate exactly how I'd like them to, but your description is more extreme than I've seen, aside from people who say it doesn't work at all.
