Creating a difference polygon

获得 Production Mapping 许可后可用。

If you are creating polygons of land uses, soils, counties, or property ownership, for example, you often need to create polygons next to one another. The polygons should share a border, but you want to avoid digitizing the border twice or having overlaps or spaces between polygons. You can use the Production Difference Polygon construction tool when creating new polygons to help ensure that your data forms a continuous fabric. With the Production Difference Polygon tool, you can digitize a new polygon that adjoins an existing polygon, using the existing polygon's geometry and the edit sketch to define the edges of the new polygon.

The Production Difference Polygon construction tool is similar to the Auto-Complete Polygon tool. However, the Production Difference Polygon tool allows you to create a new polygon that is coincident to polygons in any layer, not just polygons from the same layer.

A difference polygon created over two other polygon features

1. 启动 ArcMap。
2. 如有必要，可在地图中加载数据。
3. 在主菜单上，单击自定义 > 工具条 > 生产编辑。
4. 单击生产编辑工具条上的启动生产编辑按钮 。

   注：

   使用启动生产编辑工具开始编辑会话时，系统将自动显示管理要素和创建属性、更新属性或元数据属性窗口。

   提示：

   如果开始编辑会话时未显示创建属性、更新属性或元数据属性窗口，请单击管理要素窗口上的显示/隐藏属性按钮 。

5. Click the Create tab on the Manage Features window.
6. Choose the polygon template you want to use to create the difference polygon on the Create tab on the Manage Features window.
7. Click the Production Difference Polygon button at the bottom of the Create tab.
8. Drag a polygon in the map and double-click the end node to finish the polygon.

提示：

Preexisting polygons must overlap the polygon you created.

提示：

All the polygons you draw on the map are separate and will not merge with the others you draw.
