Did you know that SPOTLIGHT allows you to measure a straight-line distance between two points on the map?
Simply click on the Measurement tool in the MappingToolbar.
Click on the Ruler.
Map-click to place your starting point and drag the mouse to the second point. Single-click to drop a pin and proceed with another line to the next point if needed. Doubleclick when finished.
You will see your distance under the Measurement Result.
