Create circles

You can create circles interactively, from known center point and size, or based on a center point and travel rate and time.

Create circles interactively

To create circles interactively by clicking the map, complete the following steps:

1. On the ribbon, click the Map tab.
2. In the Inquiry group, click Distance and Direction .
3. In the Distance and Direction pane, click the Circle tab.
4. Click Map Point Tool .
5. Click a location on the map to designate the center point of the circle.
6. Optionally, choose a unit of measurement from the drop-down menu.
7. Click a location on the map to designate the outer edge of the circle.

   A circle is created and added to the map.

Create circles from known coordinates

To create circles using known coordinates and a known radius or diameter, complete the following steps:

1. In the Distance and Direction pane, click the Circle tab.
2. Enter a coordinate in the Center Point text box.
3. Enter a distance in the Radius/Diameter text box.
4. Press Enter or click Create Circle.

   A circle is created and added to the map.

Create circles using a time and speed

To create circles to identify potential locations for moving objects using a center point, time, and speed, complete the following steps:

1. In the Distance and Direction pane, click the Circle tab.
2. Enter a coordinate in the Center Point text box or click Map Point Tool and click a location on the map.
3. Expand Distance Calculator.
4. Enter a rate of time in the Time text box.
5. Enter a rate of travel in the Rate text box.
6. Press Enter or click Create Circle.

   A circle is created and added to the map.

Change tool units

You can change the units the tool uses to display and label outputs.

• Use the Radius/Diameter drop-down list to change the unit of measure.
• Use the Time drop-down list to change the unit of time.
• Use the Rate drop-down list to change the unit of measure.

Measure circles

The From drop-down list provides the following circle measuring options:

Option	Description
Radius	The circle is measured and labeled with a radius value.
Diameter	The circle is measured and labeled with a diameter value.
