Hi pior

I like that you made a youtube video of it. That's actually the easiest way to follow ;-).

I'm glad you could use some of it. I actually did some trial an error before I succeeded in finding a non destructive way to export/import from Moi to Fusion and vice versa. Some of the other formats altered the model wrongly.

Regarding the history feature what you could do is simply copy your model in different states and put them next to each other in chronological order. Just like my attached file with the 6 different models. This could as well be states of the same model.

What you are after seems to me to be a parametric CAD modeller where you can change every little part without changing the whole model or starting over. Solidworks and Onshape can do that and others as well. Allibre can also do it and it's much cheaper. Fusion 360 is also parametric as well.

The best systems has both direct modeling which is the usual faster modeling way and parametric which can change the model without ruining it as a whole but you have to prepare in advance to be able to go back and change different parts of the model.
