I have this model, for instance, made in www.TinkerCad.com. It is made up of a bunch of grouped objects. I'd like to be able to back it up by saving it locally, then reimport it and ungroup those objects on the imported model. Is there any way to do this?
(Note: my motivation is permanent backup of my important models. TinkerCad deleted a few million accounts in May 2021 it looks like).
When I export a model from www.TinkerCad.com I get these options:
No matter which I choose for export, if I reimport what I exported, it is now one solid piece and it appears I cannot ungroup its elements to edit them anymore.
Also, if someone else opens up my .obj file in some other tool, like Fusion360 or Solidworks (neither of which I can use right now since I'm on Linux and don't have a license for Solidworks), will they be able to edit the individual components of my model like I did in TinkerCad to build it in the first place? (I think this is NOT possible on .stls, no?--but I don't know about .obj files).
