Measuring Distance and Area
Use the Measure tool on the toolbar to measure linear distance and area on the map
based on the units chosen in the Display tab of the Options dialog box.
The snap function snaps (attaches) the point of a measurement line to a point on a road or
another measurement object. This ensures a more accurate measurement of distance or
area. To measure area, you must completely enclose the area by snapping your finish point
to your starting point.
Notes
• The Measure tool is the best way to measure short distances on the map. If you want to
measure the distance of a road, try creating a route . If you want to measure a large
area on the map, use the area object tools in the Draw tab.
• To disable the auto-snap function, hold down the ALT key on your keyboard while using
the Measure tool.
• Measure objects (lines and areas) are saved with the current project. When you create
a new project, the measure objects do not display. If you want the same measure
objects on your new project, you must recreate them.
• To view information about a measurement line, right-click it and click Info. The
measurement information is automatically displayed in the Info tab.
