I agree with the OP:s statement

"With version control"

but there are 0 reasons you can't have that in a visual application as well.

It just needs good domain model design.

I mean it's _not_ trivial. To start with you have to first understand the relationships between your model entities, and how versioning strategy affects your model hierarchy (well, graph basically), and that potentially locks you down on a certain path. But it's totally doable as a hobby project (once you know CAD systems are built - so it's not suitable as ones first CAD project ofc).
