Hello everyone!
So I was trying to build a couch but when I tried rotating my part It didn’t rotate, then I tried moving It but It didn’t move, you can drag It around and move It like that but you can’t use the rotate/ move function, I was like “yea I’ll just re- start my studio and re- open my project” but It didn’t work.
(only tools wont work)
these tools btw
Are collisions disabled?
Edit: Try disabling Constraints and Join Surfaces as well.
Yup, its disabled [ignore: characters characters]
Oh wait, I just checked It and I realized my constraints were enabled, I think I misclicked something and I accidentaly enabled It, I’m using dark mode so It was hard to notice, thank you, I never thinked of checking there lol
Disable Collisions, Join surfaces and Constraints 
hope this helps!
