Creating two intersecting circles

The Circle Circle Intersection function creates two overlapping circles. The circles are created based on two individual coordinates and radii that are defined.

Example of input and output for the Circle Circle Intersection function
Étapes :
  1. Start ArcMap.
    ConseilConseil :

    If the ArcMap - Getting Started dialog box appears, you can open a new or existing map document. You can also check the Do not show this dialog box in the future check box and click Open.

  2. On the menu bar, click Customize > Toolbars > Production Feature Builder.
  3. Click the Launch Feature Builder button Launch Feature Builder on the Production Feature Builder toolbar.

    The Feature Builder window appears in ArcMap.

    ConseilConseil :

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

  4. Choose Circle Circle Intersection in the list on the Functions tab.

  5. Define a coordinate for the start point of the polyline by doing one of the following:
    • Clicking the Pinprick button Pinprick on the Production Feature Builder toolbar, then clicking on the map
    • Typing the coordinates in the cells on the Input tab in the Coordinates area
    ConseilConseil :

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

  6. Repeat step 5 to define a coordinate for the centerpoint of the second circle.
  7. 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.

    ConseilConseil :

    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.

  8. 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.

    ConseilConseil :

    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.

  9. Click the Execute button Execute.

Two overlapping circles are created.

ConseilConseil :

If the circles do not appear, click the Add Scratch Data Layers button Add scratch data layers at the top of the Feature Builder window.
