How To Lock AutoCAD File From Editing?

Steps to Lock an AutoCAD File from Editing

To secure your AutoCAD drawing from unauthorized editing, follow these detailed steps to implement password protection and ensure only authorized individuals have access to modify your file.

Step 1: Initiate the Save As Process

1. Open the AutoCAD drawing that you want to protect.
2. Click on the “File” menu located in the upper left corner of the window.
3. Select the “Save As” option from the dropdown menu.

Step 2: Access Security Options

1. In the Save As dialogue that appears, look for the “Tools” button located at the top right corner of the window.
2. Click on “Tools” to display a drop-down menu.
3. From this menu, choose “Security Options.” This action will open a dedicated Security Options window.

Step 3: Set a Password

1. In the Security Options window, you will find a field to enter your password.
2. Type a strong password that complies with your security preferences. Ensure that it is memorable, yet difficult for others to guess.
3. Confirm the password in the appropriate field to prevent any mistakes during entry.

Step 4: Encrypt Drawing Properties (Optional)

1. While still in the Security Options window, look for an option to encrypt the drawing properties.
2. If you want an additional layer of security, check this option. Encrypting the properties will help protect sensitive information embedded in the drawing.

Step 5: Finalize and Save

1. Click “OK” to close the Security Options window and return to the Save As dialogue.
2. Choose your desired location and file name for the AutoCAD drawing.
3. Click the “Save” button to secure the file with the settings you’ve just configured.

Making AutoCAD Files Read-Only

If you also want to convert your AutoCAD file to a read-only format so it cannot be altered, use the following steps:

Step 1: Locate the File

1. Open the File Explorer on your computer.
2. Navigate to the folder where the AutoCAD file is saved.

Step 2: Adjust File Properties

1. Right-click on the desired DWG file.
2. Select “Properties” from the context menu.
3. In the properties window, locate the option labeled “Read-only.”
4. Check the box next to “Read-only” to enable it.
5. Click “Apply” and then “OK” to confirm the changes.

Step 3: Confirm Read-Only Status

1. To ensure that the file is now read-only, try reopening it in AutoCAD. Attempt to make changes to the drawing; if successful, return to the properties to verify it is set correctly.
