How To Turn Ortho On In AutoCAD?

Understanding Ortho Mode in AutoCAD

Ortho Mode is a powerful tool in AutoCAD that helps you maintain precise cursor movement while drawing. It restricts your cursor to horizontal and vertical directions, which is particularly useful when creating straight lines and aligning elements in your designs. Here’s how you can easily activate and use this feature.

How to Activate Ortho Mode

1. Using the Keyboard Shortcut (F8):

   • The quickest way to toggle Ortho Mode is by pressing the F8 key on your keyboard. When activated, your command line will display “ORTHO On,” indicating that your cursor is now constrained to horizontal and vertical paths.

2. Using the Status Bar:

   • Locate the Status Bar at the bottom of your AutoCAD workspace. You’ll see an icon representing Ortho Mode, usually depicted as a rectangle or a grid-like symbol. Click on this icon to toggle Ortho Mode on or off.

3. Accessing Through the Command Line:

   • You can also enable Ortho Mode via the command line. Simply type ORTHO and press Enter. Then, type On to activate it.

Fixing Ortho Mode Issues

Sometimes, users may encounter issues where Ortho Mode does not work as expected. Here are a few troubleshooting steps:

1. Check Function Lock Settings:

   • If F8 isn’t responding, ensure that your Function Lock (Fn) key isn’t inadvertently altering its functionality. Hold down the Fn key while pressing F8 to see if this resolves the issue.

2. Adjust Command Settings:

   • The command TEMPOVERIDES can affect how AutoCAD responds to certain commands. To ensure smooth operation, type TEMPOVERIDES in the command line and set its value to 0.

3. Software Updates:

   • Make sure you have the latest updates for AutoCAD 2025. Sometimes bugs can cause features like Ortho Mode to malfunction. Check for any pending updates and install them.

Key Features of Ortho Mode

• Precision Drawing: By constraining movement, Ortho Mode minimizes errors when drawing lines or aligning objects.
• Vertical and Horizontal Alignment: It assists in creating rectangular shapes, aligning elements easily, and maintaining accuracy in layouts.
• User Coordinate System (UCS) Compatibility: Ortho Mode operates relative to the UCS, ensuring that your work is aligned correctly regardless of the coordinate settings.
