Draw and Measure tools and their icons

​Tool name​Tool description

Add point

Draws a point on the map for each click of the mouse button.

Add line

From a starting point, each click on the map defines the beginning and end point of a segment of the line. You must double-click the left mouse button to complete the line.

Trace a freehand line

Click and hold the left mouse button and move the mouse where you want the line to be drawn. Release the left mouse button to finish.

Add polygon

Each time you click on the map a vertex or corner will be added. Think of a polygon as a rubber band and each time you click on the map you are gluing the rubber band to that point on the map. When you are drawing a polygon it is best to draw in a clockwise rotation. You must double-click the left mouse button to complete the polygon.

Trace a freehand polygon

From your starting point, after you press the left mouse button down on the map at the start, hold it down and move the mouse around the map. The polygon is drawn following the mouse location until the left mouse button is released.

Add a rectangle

Draws a rectangle area or polygon - usually from a top-left corner to a bottom-right corner (hold down the mouse to start and let go to finish).

Add text

Writes text on your map in the position you choose by using a mouse click with the left button.

Add a triangle

Draws a triangular area polygon – click and drag and let go of the mouse to finish.

Add an arrow

Draws an arrow area polygon – click and drag and let go of the mouse to finish.
