I have made a basic shape in a tinkercad project. Now I need to split this project into 4 different projects. In the "My Designs" menu, I can see my project, but there is no "duplicate" or "save as". I don't want to have to recreate this basic shape 4 times because it has rounded edges that were difficult to make.
So, just to be clear, I am not talking about duplicating an object within a project (or design), I mean making duplicating the whole design into a new design file. It is basic file management, surely there must be a way.
