I would also really like to know what units my models are measured in, and how to even find that out. None of the menus seem to actually tell me what size my selected object is. It makes modelling anything hard when you don’t know whether the overall model is the size of a mouse or a mountain. I just discovered this app and feel like I can’t make use of it until this is figured out, and the calliper tool does nothing except spit out some arbitrary number. This seems to be the only thread that touches on this problem
