I agree — I play on the Switch, so unfortunately I’m in the same boat. However, it seems the issue was caused by a software glitch and is currently being patched. From what I can tell, PMC is already back to around 50% functionality with the 3D Viewing tool. So just bear with the PMC staff for a little longer. This should be resolved soon, and we can all get back to working on our passion projects.
I love this feature so much, as somebody that really struggles to imagine things, and then put pen to paper it was a lot of help. WIll this be permanent? I think it would help if PMC would just say something about it...
