How to see the history of a model?

Hello,
I would like to create a new model inspired by one of my other models and for that I would need to see the different steps that allowed me to create the model until its finality. Can you tell me how or even the steps that allowed me to create a model knowing that I reopened my session after 3 months?

Thanks in advance,

Good day.

I think you can’t. once the file is closed, the undo history is purged. maybe you came from a parametric environent which is not like Rhino. you don’t have feature history in Rhino

not for your current files but for future files, you can install CommandTracker from Packagemanager. I haven’t tried it myself yet.

OK, thanks

OK, thanks.
