Ortho Command in AutoCAD

The Ortho command in AutoCAD is a feature that helps users draw straight lines either horizontally or vertically. It ensures that lines snap to 0 or 90-degree angles, making it easier to create precise drawings. This guide explains how to use the Ortho command step by step.

Step 1: Open AutoCAD

Start AutoCAD and load a new or existing drawing. Ensure that you have access to the drawing area and the status bar, where the Ortho mode toggle is located.

Step 2: Locate the Ortho Command

The Ortho command can be activated from the status bar or by using a keyboard shortcut:

• Look for the Ortho Mode button on the status bar (usually labeled as "Ortho").
• Alternatively, press the F8 key on your keyboard to toggle Ortho mode on or off.

Step 3: Turn On Ortho Mode

To activate Ortho mode:

• Click on the Ortho button in the status bar, ensuring it is highlighted.
• Or, press the F8 key to turn Ortho mode on. You will see a message in the command line confirming the mode is enabled.

Step 4: Use the Line Command with Ortho Mode

Once Ortho mode is on, you can use it with commands like LINE to draw straight lines. Follow these steps:

1. Type LINE in the command line and press Enter to activate the Line command.
2. Specify the first point by clicking in the drawing area or entering coordinates.
3. Move your cursor horizontally or vertically. Notice that the line snaps to 0 or 90-degree angles automatically.
4. Specify the next point and press Enter to complete the line.

Step 5: Toggle Off Ortho Mode (If Needed)

If you need to draw lines at arbitrary angles, you can turn off Ortho mode:

• Click the Ortho button in the status bar to deactivate it.
• Or, press the F8 key again to toggle it off.

When Ortho mode is off, lines can be drawn freely without snapping to specific angles.

Step 6: Save Your Work

After using Ortho mode to draw precise lines, remember to save your drawing. Click on File > Save, or type SAVE in the command line and choose a location for your file.

Conclusion

The Ortho command in AutoCAD is a valuable tool for creating straight horizontal or vertical lines, ensuring precision in your designs. By following these steps, you can enable, use, and toggle Ortho mode efficiently. Practice incorporating it into your workflow to improve your drafting skills.
