To measure distance:

  1. Click the Draw & Measure button.

You can also draw a line with multiple segments, and the total distance along the line will display. To draw multiple segments, single-click at the end of each segment, and then double-click at the end of the line.

To measure area:

  1. Click the Draw & Measure button.
