Splitting polygons

The Cut Polygons tool allows you to cut selected polygons into multiple polygons by drawing a polyline sketch where the polygons are to be split. Each polygon that is created by the split becomes a new feature but inherits the attributes of the feature from which it has been created.

步骤:

1. Start ArcMap.

2. If necessary, load data in the map.
3. On the main menu, click Customize > Toolbars > Production Editing.
4. On the main menu, click Customize > Toolbars > Production Editing Advanced.
5. Click the Production Start Editing button on the Production Editing toolbar.
   注意:

   The Manage Features and Create Attributes, Update Attributes, or Metadata Attributes windows automatically appear when you start an edit session using the Production Start Editing tool.

   提示:

   If the Create Attributes, Update Attributes, or Metadata Attributes window does not appear when you start an edit session, click the Show/Hide Attributes button on the Manage Features window.

6. Select one or more polygon features.
7. Click the Cut Polygons Tool button on the Production Editing toolbar.
8. Draw a line across the selected polygons, ensuring that it intersects the existing polygons in a minimum of two locations.
9. Double-click the end node to finish the line sketch.

The polygons are divided where the line has been drawn.
