Why? How to fix it? Has anyone come across?

You are right

So, I don’t understand something at all, if I import .3dm into AutoCAD, then everything is fine, if I import a .dwg created in AutoCAD (or Rhino) into Rhino, then everything is bad. What’s the matter?

Rhino cares more!
I don’t know, perhaps a tolerance difference…
