- Repeat step 5 to define a coordinate for the centerpoint of the second circle.
-
Click the cell next to Radius 1 and type a value for the radius of the first circle.
This is the radius of the first circle. The default unit is Nautical Miles.
Conseil :
You can right-click the parameter name and change the unit of measurement. If you change the unit of measurement after defining a value, the value is converted to the new unit of measurement, and you may need to redefine the value.
-
Click the cell next to Radius 2 and type a value for the radius of the second circle.
This is the radius of the second circle. The default unit is Nautical Miles.
Conseil :
You can right-click the parameter name and change the unit of measurement. If you change the unit of measurement after defining a value, the value is converted to the new unit of measurement, and you may need to redefine the value.
