After several years of people complaining about this it seems it still exists. Am i missing a way to un-union an object to make minor fixes? This seem like a pretty basic feature that should exist.
Hi,
As of now, Shapr3D is a direct modeling software, meaning once a change is made, there is no history about how it was created. As such, there is no way to un-union, since the app doesn’t know if the body was created using union or not.
We might have something in store for you though, stay tuned
