Show Rulers
Check Show Rulers in the View menu to show rulers. They appear along the top and left side of the drawing area. By default, the ruler's origin (0|0) is the same as the grid's point of origin. Disable Show Rulers in the View menu to hide rulers again. Rulers are an assistance to create the map layout.
