Populating the z-value with a bias

With the Populate Z for selected features tool, you can modify the z-values on existing features by adjusting them using a specified value. For example, if you indicate that the z-value should be adjusted by 10, the z-values on the vertices on the selected features are reduced by a value of 10.

Steps:

1. Start ArcMap.
2. If necessary, load data in the map.
3. On the main menu, click Customize > Toolbars > Production Editing.

   Tip:
