Choosing the bridge target feature class

此主题仅适用于 ArcEditor 和 ArcInfo。

Before you can create features with the Make Bridge tool, a target feature class must be specified for the bridges. You can choose which feature class to use as the target layer for bridges on the Defense Mapping Properties dialog box on the Feature Classes tab. Any feature class loaded in the map can be selected, but it is recommended that you use the bridge feature class in the data model you are using for data extraction.

步骤:

1. Start ArcMap.
   提示:

   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 main menu, click Customize > Toolbars > Defense Mapping.
3. If necessary, start an edit session in ArcMap.
4. On the Defense Mapping toolbar, click Defense Mapping > Options.

   The Defense Mapping Properties dialog box appears.

5. If necessary, click the Feature Classes tab.
6. Click the Bridge Line Feature Class drop-down arrow and choose the line feature class you want to use as the target layer for building line features.
7. Click OK.
