Teach you how to repair and protect AutoCAD files

Repair method: If the degree of damage to AutoCAD files is not too serious, you can generally use the RECOVER command to repair, you can also try to insert the damaged file into the new file with the INSERT command. Save it again.

The main cause of damage to the CAD file is the power outage in the absence of precautions, and the fact that the file is forcibly terminated without being opened during the opening process.

Protection: First find the "File Security Measures" in the "Open & Save" dialog box and select “Auto Save ”. If the file is broken, change the suffix name of the backup file to DWG to replace the bad file.

It is also worth noting that, based on my years of experience in using CAD, I feel that the English version of the CAD software has a much smaller dead frequency during use, so I believe that the English version is the first choice for reducing file errors.
