Circle Guide

The ‘Circle guide’ tool will display the radius and total area covered by the set circle. To use the tool, drag the square center marker of the circle to the desired point or enter the coordinates. Then, click on the node at the perimeter of the circle and drag it in or out until the desired radius is achieved. Alternatively, you can enter the circle radius if it is known. Hit apply to overlay the circle outline onto the map.
