How To Recover Invalid DWG File?

Steps to Recover a Corrupted DWG File

When faced with the challenge of recovering a corrupted DWG file, you can follow these systematic steps:

Step 1: Launch AutoCAD

Begin by opening the AutoCAD application on your computer. Ensure that you have the latest version installed or at least AutoCAD 2025.

Step 2: Open the Corrupted File

Go to the File menu and select Open. Navigate to the location of the corrupted DWG file. Select the file and click on the Open button. If a warning appears, choose to open it anyway.

Step 3: Use the Recover Tool

Once the corrupted file is open, look for the AutoCAD icon located in the Tools column. Click on it, then navigate to Drawing Utilities and select Recover. This feature is specifically designed to analyze and automatically repair damaged DWG files.

Step 4: Review the Repaired File

After the recovery process is completed, AutoCAD will display the repaired file. Examine the drawing meticulously to ensure that all elements are intact. Pay attention to any irregularities or errors that may still exist.

Step 5: Save the Repaired File

Once you have verified that the recovery was successful, save the repaired DWG file. Use the Save As option to create a new version of the file, ensuring you do not overwrite the original corrupted file.

Additional Tips for DWG File Recovery

  • Backup Files Regularly: To minimize the risk of losing important data, regularly backup your drawing files.
  • Keep Software Up to Date: Using the latest version of AutoCAD ensures you benefit from the latest recovery features and fixes.
  • Cloud Storage Considerations: If your files are stored in the cloud, ensure that there are no syncing issues before attempting recovery.

Common Queries

What should I do if the DWG file is still not opening after recovery?

If the file does not open after using the Recover tool, try using the Audit command under the Tools menu, which can help identify and fix issues within the file.

Can I restore previous versions of my DWG files?

Yes, if you have set up automatic backups in AutoCAD, you can locate the backup files in the designated automatic save location, typically found in the Options under the Files tab.

Why does my AutoCAD file open as read-only?

A DWG file may open as read-only if it has been marked as such, or if the file permissions in Windows do not allow editing. Right-click the file, select Properties, and ensure that the ‘Read-only’ checkbox is unchecked.
