Configuring the z snapping environment

When you are creating features and modifying data, there are times where you want to be able to snap to the nearest vertex, edge, or endpoint to ensure the feature's appearance or geometry is correct. Customarily, only x- and y-values are used to determine snapping behavior, but z-enabled features can also use snapping during an edit session. When a feature is snapped to an x,y position, the z-value for the position is set as the current z-value, which ensures that the newly created feature is coincident to the existing feature in all three dimensions.

手順:

1. Start ArcMap.
   ヒント:

   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. If necessary, load z-enabled data in the map.
3. On the main menu, click Customize → Toolbars → Production Editing.
4. If necessary, enable classic snapping on the Production Editing toolbar by clicking Production Editing → Use Classic Snapping.
5. Click the Production Start Editing button on the Production Editing toolbar.
   メモ:

   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.

   ヒント:

   If the Create Attributes, Update Attributes, or Metadata Attributes window does not appear when you start an edit session, click the Link Feature Manager To Attributes Window button on the Manage Features window.

6. On the Production Editing toolbar, click Production Editing → Snapping Window.

   The Snapping Environment window appears.

7. If necessary, dock the window in ArcMap.
8. Check the check boxes next to the layers you want to configure for snapping.

9. On the Production Editing toolbar, click Production Editing → Production Z Snapping Window.

   The Production Z Snapping window appears. The layers with options specified in the Snapping Environment window are available to choose.
10. Check the check boxes next to the layers with which you want to use snapping with z-values.
    ヒント:

    You can refresh the layers available for z snapping by clicking Refresh on the Production Z Snapping window.
