How to Use the Sketch Tool
Click on Sketches within the Map Legend to enable the tool.
To create a sketch, click on the Sketch tab and click on the Create a Sketch button at the bottom of the Sketch panel.
The Sketch panel will open on the left hand side of your map. Here you can set a name and description for the sketch.
Sketches are designed to be shared and worked on collaboratively, so by default new sketches can be edited by anyone with the sketch URL. If you would like to prevent others from editing your sketch, uncheck the box "Allow sketch to be edited by others".
Once you have set your sketch name and edit settings, click Done to continue to the drawing tools.
Sketch allows you to create line, polygon, rectangle, oval, marker, and text annotations on your maps.
To place a marker, select Create a marker from the tool bar and click on the map to place the marker. You can select a color from the range provided. If you need to re-position the marker, simple hover your mouse over the marker, and click and drag the marker to the preferred location.
To save the marker, click the Done button.

To adjust the size or position of shapes, click on the white box nodes and drag to your preferred shape or size.
NOTE:
Extremely large circles may appear to be compressed if placed near the top or bottom of the map boundary; however, they occupy the same amount of area. This is due to the distortion of the web Mercator map projection.
