How to fix Drawing file is not valid AutoCAD error?
1. Make sure the files you’re trying to open are compatible with your CAD software
When it comes to CAD software format compatibility issues, it is recommended that you use the same version of the software in which the files were originally created. In order to find out in which CAD software and which version they were created, follow these steps:
- Right-click on the file that’s causing the error message -> Open with -> select a text editor from the programs list.
- Inside the text editor, search for a value code at the start of the ‘text’.
- That will be the version of the software that was used to create that file.
- Check online to see if that version of the software is still available for download.
Note: Files with the format .DWG, and .DXF can only be worked with if your version of the software isn’t older than the version of the software in which they were created in.
2. Use another software to open the DWG file
- Right-click the file that’s causing issues -> select Open with -> choose another compatible software (AutoCAD mobile in my case).
- After opening the file in the CAD software of your choosing, export it as a new file with either .DWG or .DXF format.
- Re-try to open the file in your initial CAD software.
In case you don’t have another compatible software on your PC, follow these steps:
- Right-click the .DWG file -> Open with -> Search the Store.
- Choose an application from Windows Store and repeat the steps found in Method 2.
