Understanding Safe Mode in AutoCAD

Safe mode is a special startup option for AutoCAD designed to help users troubleshoot issues by running the application with minimal functionality. This mode disables certain features and can be beneficial when trying to avoid complications from add-ons or custom settings. Here’s a detailed guide on how to start AutoCAD in safe mode.

Activating Safe Mode

  1. Close AutoCAD: Ensure that AutoCAD is completely closed before attempting to start it in safe mode. This prevents any conflicts with open files or settings.

  2. Access the Shortcut: Locate the AutoCAD shortcut on your desktop or in the Start menu.

  3. Modify Shortcut Properties:

    • Right-click on the AutoCAD shortcut and select Properties from the context menu.
    • In the Properties window, find the Target field. This field shows the path to the AutoCAD executable.

  4. Add the Safe Mode Switch: At the end of the text in the Target field, add the following:

    /safemode

    Ensure there is a space between the existing path and the /safemode command.

  5. Apply the Changes: Click OK or Apply to save the changes to the shortcut.

  6. Launch AutoCAD: Go back to the desktop or Start menu and double-click the modified shortcut. AutoCAD will now start in safe mode.

Considerations When Using Safe Mode

  • Limited Functionality: Understand that running AutoCAD in safe mode disables certain features, including themes, add-ons, and Express Tools. This is intentional to help isolate issues.

  • Troubleshooting Utilities: Use this mode primarily for troubleshooting. If AutoCAD runs smoothly in safe mode, your problems may be related to specific customizations or third-party add-ons.

  • Settings Restoration: After identifying the issue, you can reset settings or uninstall problematic add-ons. To return to normal mode, simply launch AutoCAD using the standard shortcut without the /safemode command.

Frequently Asked Questions

Can I run AutoCAD in safe mode permanently?
No, safe mode is intended for troubleshooting only. It’s not meant to be used as a permanent startup option.

Will my custom settings be lost when I run AutoCAD in safe mode?
No, your custom settings remain intact. Safe mode simply prevents those settings from loading during the session.

How do I get out of AutoCAD’s safe mode?
To exit safe mode, close AutoCAD and relaunch it using the standard shortcut, ensuring that the /safemode command is removed from the Target field.
