Not automagically, or easily, except in certain special trivial cases, it's one of the most advanced, least-fun things you can do with Rhino. The software that claims to do it automatically costs a ton and produces generally very nasty results. So the next question would be, do you really really need to do this, what is the end goal?
I mistakenly deleted a .3dm file from a flashdrive thinking it was a duplicate. I have the .stl file of that model but wanted to make a few slight changes.... seems I might be out of luck. Lesson learned.
