Solutions for Fixing Corrupt AutoCAD Files

Using the Recover Command

When faced with a corrupt AutoCAD file, one of the first steps you can take is to utilize the Recover command. This feature allows AutoCAD to attempt to repair the file and recover as much data as possible.

To use the Recover command, follow these steps:

1. Open AutoCAD and click on the “Application” menu in the top-left corner.

2. Hover over the “Drawing Utilities” option and select “Recover” from the submenu.

3. Browse for the corrupt file and select it.

Click the “Open” button to initiate the recovery process. 4.

AutoCAD will analyze the file and attempt to fix any errors or corruption. If successful, it will generate a log file with details of the recovery process.

5. Save the recovered file to a different location or with a different name to prevent overwriting the original file.

Using the Auto save Feature and Backups

AutoCAD provides an Auto save feature that automatically saves your work at regular intervals, helping to minimize data loss in the event of file corruption. Additionally, creating regular backups ensures an extra layer of protection for your files.

Here’s how you can take advantage of these features:

1. Enable Auto save: Go to the “Options” menu by clicking the “Application” menu in the top-left corner, then selecting “Options” from the dropdown.

In the Options dialog box, navigate to the “Open and Save” tab. Increase the frequency of Auto save intervals to safeguard your work against unexpected crashes or power outages.

2. Back up your files: Make it a habit to create manual backups of your AutoCAD files periodically.

This can be done by simply copying the file to a separate location or external drive. Maintaining multiple versions of your files ensures that even if one becomes corrupt, you have a previous working version to fall back on.

Other Steps to Take

In addition to using the Recover command and implementing Auto save and backups, there are other steps you can take to recover and prevent further issues with your AutoCAD files:

1. Recover Drawing: If the Recover command doesn’t fully restore your file, consider using the “Recover Drawing” option from the “Application” menu.

This method attempts to recover drawing-specific data that may have been lost. 2.

Purge Unused Elements: AutoCAD files can accumulate a significant amount of unused elements, such as blocks, layers, or linetypes. By using the PURGE command, you can remove these unnecessary elements, reducing file size and potentially resolving any corruption caused by conflicting or redundant components.

3. Audit the Drawing: The AUDIT command identifies and repairs any errors within the drawing file.

To use this command, access the “Application” menu, choose “Drawing Utilities,” and then select “Audit.” Follow the prompts to scan and repair any issues. 4.

Save As: If you manage to open a corrupt file successfully, immediately save it under a different name using the “Save As” function. This creates a separate copy of the recovered file while keeping the original intact.

It serves as a precautionary measure in case further corruption occurs during editing.

Additional Recovery Methods

Using the Copy and Paste Method

Another method to recover data from a corrupt AutoCAD file is the copy and paste technique. To utilize this method, follow these steps:


Open a new AutoCAD session. 2.

Open a blank drawing file. 3.

Return to the corrupt drawing file. 4.

Use the “Window” selection or any other selection method to choose the desired geometry, text, or other entities you want to recover. 5.

Press “Ctrl+C” or right-click and select “Copy.”

6. Switch to the new blank drawing file and press “Ctrl+V” or right-click and select “Paste.”


Save the new drawing file with a suitable name, ensuring it does not overwrite the original corrupt file.

Using the Recover and Overkill Commands

In some cases, a combination of the Recover and Overkill commands can help salvage data from a corrupt AutoCAD file. 1.

Open AutoCAD and the corrupt file. 2.

Once the file is open, access the “Drawing Utilities” submenu within the “Application” menu. 3.

Select the “Recover” option and specify the problematic file. 4.

Upon completion of the recovery, use the “Overkill” command. This command can remove redundant or overlapping geometry, repairing potential issues caused by corruption.

5. Save the fixed drawing under a new name to avoid replacing the original corrupt file.
