Otherwise, this message indicates that the drawing file has been damaged beyond use. However, there are a few things that may get it to open or more variant you may see on threads below

In case threads and the guide aren't effective, then try to use more powerful solution for complicated AutoCAD corruptions https://www.openfiletool.com/dwgopen.html DWG Open File Tool

 

First, open a blank DWG and run the RECOVER command. You can then browse to the problematic file, and AutoCAD will attempt to repair any errors it finds. Save the file, and then see if everything works as you expect it to. If not, continue on to the steps below:

1) Open the problematic file and make sure all layers are on and thawed.

2) Detach any XREF's.

3) Type in -PURGE at the command line (remember to enter the dash before the command). Type R for RegApps. Delete all RegApps in the file. It is not necessary to do them one by one because sometimes there can be thousands and it would take a very long time.

4) Type AUDIT, and select Y for yes to audit the file of any errors.

5) Type PURGE and purge the file of anything that can be purged.

6) Using the WBLOCK command, block out all the information in the file to create a new drawing. Select the objects by windowing them; do not just type ALL.

7) Open a blank DWG. Do not use any templates. (Set the STARTUP variable to 0, and then open a file if you are unsure if you are using templates)

8) Using the INSERT command, insert the file created in step 6.

9) EXPLODE the newly inserted information so it is not a block any longer.

10) Test to see if the file now works correctly. If it does, you can start to add in the Xref's again one by one. Test the file after each insertion. If the problem returns after inserting an Xref, you'll know that that file needs to be cleaned using these steps as well.

As a final note, I highly recommend running the AUDIT and PURGE commands before each save. This will keep the file clean and greatly reduce the chance of any corruption setting in. You too can have clean files by following these steps!

I’m sorry to hear you’re having trouble opening your AutoCAD drawing. Here are a few steps you can try to resolve the issue:

1. Check the File Format: Ensure the file you're trying to open is indeed a .dwg file. Sometimes, file extensions can be misleading.

2. Update AutoCAD: Make sure you have the latest version of AutoCAD installed. Software updates often fix bugs that may prevent files from opening.

3. Repair the Drawing:

   • Use the RECOVER command. Open AutoCAD, type RECOVER in the command line, and select your drawing file. This command attempts to fix corrupt files.
   • You can also try the AUDIT command to check and fix errors within the drawing.

4. Try a Different Computer: If possible, try opening the drawing on another computer with AutoCAD installed. This can help determine if the issue is with your software or the file itself.

5. Backup Files: If you have backup copies or previous versions of the file, try opening those. AutoCAD often creates .bak files that can be renamed to .dwg and used.

6. Check for File Locks: Sometimes, the file might be locked by another process or user. Ensure that the file is not open elsewhere or being accessed by another program.

7. Third-party Tools: There are third-party tools available that can attempt to repair corrupt AutoCAD files. Use these as a last resort.

8. Contact Autodesk Support: If none of the above steps work, contacting Autodesk support or checking their forums might provide a solution specific to your issue.

I hope one of these solutions helps you get your drawing open. Let us know how it goes or if you need further assistance!

Best of luck!
