How Do You Use Orthomode in AutoCAD?

In AutoCAD, the Orthomode feature is a powerful tool that allows you to work more efficiently by restricting cursor movement to 90-degree angles. This is particularly useful when drawing or editing lines, as it ensures precision and accuracy in your designs.

Enabling Orthomode

To enable Orthomode in AutoCAD, follow these simple steps:

  1. Click on the “Ortho” button located on the status bar at the bottom of the AutoCAD window. Alternatively, you can press the F8 key to toggle Orthomode on or off.
  2. Once enabled, Orthomode will restrict your cursor movement to horizontal and vertical directions only. You will notice that as you move your cursor, it will snap to these 90-degree angles.

With Orthomode enabled, you can draw lines, rectangles, and other geometric shapes more easily. It helps maintain clean edges and avoids accidental diagonal lines that may disrupt the overall design.

Using Orthomode for Drawing

When drawing with Orthomode turned on:

  • The line command: When using the line command, your cursor will only move horizontally or vertically. Simply click to start your line and then move your cursor in the desired direction.

    Click again to finish the line segment.

  • The rectangle command: With Orthomode enabled, drawing a rectangle becomes a breeze. Start by specifying one corner of the rectangle and then move your cursor horizontally or vertically to define its width and height. Click again to complete the rectangle.

You can see how Orthomode streamlines the drawing process by eliminating any guesswork and ensuring precise alignment of elements.

Using Orthomode for Editing

Orthomode is not only helpful for drawing but also for editing existing objects in AutoCAD. When using commands such as move, rotate, or scale, Orthomode restricts the movement to 90-degree angles.

The move command: With Orthomode enabled, you can easily move objects horizontally or vertically by specifying a base point and then moving your cursor in the desired direction. This makes it simple to align objects accurately.

The rotate command: When rotating objects, Orthomode ensures that the rotation is limited to 90-degree increments. This is useful when you need to precisely align elements within your design.

The scale command: Orthomode helps maintain proportionality while scaling objects. Whether scaling uniformly or in one direction, your cursor will snap to horizontal or vertical directions as you adjust the scale factor.

Disabling Orthomode

If you need to temporarily disable Orthomode while working in AutoCAD:

  1. Click on the “Ortho” button on the status bar again or press the F8 key once more. This will turn off Orthomode and allow free cursor movement.

You can always re-enable Orthomode later by following the same steps mentioned earlier.

In Conclusion

The Orthomode feature in AutoCAD enhances precision and efficiency by restricting cursor movement to 90-degree angles. Whether drawing or editing objects, this tool ensures accurate alignment and clean geometries. By enabling Orthomode, you can streamline your workflow and produce professional designs with ease.
