The Ortho command restricts the movement of the cursor to multiples of a specified angle from the last point created.

Note

• The Ortho command, clicking Ortho in the status bar, and the F8 key, are all toggles. Holding Shift changes the mode while you hold the key down.
• The SetOrtho command prompts for a setting with the options On, Off, and Toggle. This is useful for inclusion in a script for the ReadCommandFile command.
• When Ortho is on, marker movement is restricted to points at multiples of a specified angle from the last point created. The default angle is 90 degrees.
