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.

    提示提示:

    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 Show/Hide Attributes on the Manage Features window.

  6. Select one or more polygon features.
  7. Click the Cut Polygons Tool button Cut Polygons on the Production Editing toolbar.

The polygons are divided where the line has been drawn.
