Creating a circle

获得 Production Mapping 许可后可用。

The Circle function creates a geodesic circle that can be used to represent a buffer surrounding a single bearing. The circle is created based on a single input point and a specified radius.

1. 启动 ArcMap。
2. On the menu bar, click Customize > Toolbars > Production Feature Builder.
3. Click the Feature Builder button on the Production Feature Builder toolbar.

   The Feature Builder window appears.

   提示：

   The Feature Builder window can be placed anywhere in ArcMap, or in the Table Of Contents window, with the aid of the arrows showing the possible placement positions.

4. If the scratch dataset has not been added to the table of contents, click the Add Scratch Data Layers button at the top of the Feature Builder window.

   The dataset is added to the map using the current spatial reference.

5. Choose Circle in the list on the Functions tab.

   

6. Define a coordinate for the start point of the polyline by doing one of the following:
   • Click the Pinprick tool on the Production Feature Builder toolbar and click the map
   • Type the coordinates in the cells on the Input tab in the Coordinates area.

   提示：

   To view the input coordinates on the map, double-click the row headers for each coordinate.

7. Click the cell next to Radius and type a value for the radius of the circle.

   This is the radius for the circle the function is going to create. The default unit is Nautical Miles.

   提示：

   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.

8. Click the Execute button .

A circle is created surrounding a central point.
