Yes testing is such a big problem for those coders.

I use Fusion 360 primarily but it is available in other CAD software, this is a decent description:

Timeline and Rollback: The timeline in Fusion 360 visually represents the design history, showcasing the sequence of features and operations. You can review, reorder, and modify design steps using the timeline. The rollback feature allows you to return to a specific point in the timeline and make edits, facilitating design iteration and exploration.

It has made working on interactive designs significantly easier for me, and saves a tremendous amount of time and effort.

Do they have editable history yet? That’s a big blocker for me jumping.

This is giving me PTSD

This is the best programming joke I have seen in at least a week.
