How to Save Read Only File in AutoCAD?

When working with drawings in AutoCAD, you may encounter scenarios where files are marked as read-only. This limitation can be frustrating if you intend to make modifications. Understanding how to save a read-only file is crucial for effective workflow. Here’s a detailed guide on how to manage and save read-only files in AutoCAD.

Understanding Read-Only Files in AutoCAD

Read-only files indicate that modifications cannot be made to the existing document. This status can arise due to various reasons, such as file permissions, a shared file being accessed by another user, or settings within AutoCAD itself. It’s important to identify the cause before attempting to make changes.

Steps to Save a Read-Only File in AutoCAD

1. Set AutoCAD to Run as Administrator

Running AutoCAD with elevated permissions can sometimes bypass restrictions on files:

• Right-click the AutoCAD shortcut on your desktop or in the Start menu.
• Select "Run as administrator" from the context menu.
• This allows AutoCAD to have more control over file permissions and may help you save your changes.

2. Use the ‘Save As’ Option

If you are unable to save the file due to its read-only status, try saving it under a new name:

• Open the read-only file in AutoCAD.
• Go to the "File" menu and select "Save As."
• In the dialog that appears, choose a different location or rename the file to avoid overwriting the existing one.
• Click “Save.” This will create a new copy that you can edit freely.

3. Adjust File Properties

Sometimes, the file’s properties might be set to read-only:

• Locate the DWG file in File Explorer.
• Right-click the file and select "Properties."
• In the General tab, uncheck the "Read-only" box.
• Click "OK" to apply the changes. This enables you to edit and save the file without restrictions.

4. Check Folder Permissions

If multiple files are showing as read-only, it might be a permissions issue at the folder level:

• Navigate to the folder where the DWG file is stored.
• Right-click on the folder and select "Properties."
• Go to the "Security" tab and verify that your user account has "Full control" or at least "Modify" permissions.
• If needed, click "Edit" to change permissions.

5. Consult the File Type Locking

Certain file types, like those saved in cloud services (e.g., BIM 360), may open as read-only:

• Make sure the file is not being accessed by another user.
• If it’s locked due to being saved in a cloud-based service, you may have to download it locally to make changes.

6. Disable AutoCAD’s Backup Settings

AutoCAD’s backup feature can sometimes interfere with saving:

• Open AutoCAD and enter the command ISAVEBAK in the command line.
• Change the setting to “0” to disable the backup on save.
• This might help if AutoCAD is trying to save a backup instead of a new version of your file.

Frequently Asked Questions

What does it mean when a file is marked as read-only in AutoCAD?
A read-only file in AutoCAD means that it is currently set to prevent modifications. This can happen if the file is already open by another user or if its properties are set to read-only.

How do I check if another user is accessing my AutoCAD file?
If your file is on a network, you can right-click the file in Explorer and select "Properties" to check for any active sessions. If the file is noted as "In use" or has open handles, it is being accessed by someone else.

Can I permanently change a read-only file to editable?
Yes, by changing the file’s properties to remove the read-only attribute and ensuring that you have the necessary permissions, you can convert a read-only file to an editable format in AutoCAD.
