Orthogonal Mode restricts the movement of the cursor to be parallel to the X-axis or the Y-axis of the current coordinate system. For example, with the default 0-degree orientation (angle 0 at the "three o'clock" or "east" position), when the Orthogonal Mode setting is enabled, lines are restricted to 0 degrees, 90 degrees, 180 degrees, or 270 degrees. As you draw lines, the rubber-banding line follows either the horizontal or vertical axis, depending on which axis is nearest to the cursor: type the length of the line in the command bar, then press Enter.

Do one of the following:
- Click the ORTHO field in the Status Bar.
- Press the F8 function key.
- Press and hold the Shift key.
- Type ortho in the command bar, then choose the appropriate setting.
