The PERPENDICULAR AT LENGTH command draws a line of a specified length from an entity to a point perpendicular to the entity. To draw a perpendicular line without a specified length, use the LINE-PERPENDICULAR command.

To draw a perpendicular at length line, select Draw > Lines > Perpendicular at length:

The prompt reads "Length [n]:" Select the length of the line to be drawn. Right-click to accept the default or prior length. Type a new length in any units or use the mouse to visually select two points the desired distance apart.
The prompt reads "Entity:". Select the entity from which you want the new line to be perpendicular.
Select a second point anywhere along the line you are about to draw. The line is automatically drawn with the prescribed length, perpendicular to the selected entity. Continue selecting points, if desired. Press the right button to end the command.

This command can be used to create ridges with a specific line length (e.g around a moat). It can also be used to create railway lines.
