corrupted files in autocad 2016

[phantomato]

Good afternoon,
using autocad 2016, I have many files of this type, one of the files of a couple of days ago in opening of the following released: file design is not valid.

Is there a way to open a file without losing data?

you can try with recover
file -> utility -> recover (or restore, apparently, in Italian)

first, open a dwg file in white and run the command recovers. you can browse to locate the problematic and autocad file will try to repair any errors it finds. save the file and then see if everything works as you expect to. if you cannot apply https://dwg.recoverytoolbox.com/it/ recovery toolbox for dwg
