Ways of populating z-values during an edit session

When you are editing a selected set of features, you have several options for populating the z-value. The Populate Z for selected feature(s) tool provides you with several different options:

• Populate Zs from surface-Z—Values from a functional surface file are used to populate the selected features' z-values.
  Nota:

  The 3D Analyst extension must be installed to use this option.

• Populate Zs from attribute—Z-values are populated using an attribute field such as ZV2.
• Populate Zs from value entered—The value that is typed into the Populate Zs from value entered text box is used as the z-value for the selected set of features.
• Adjust Zs by value (BIAS)—Z-values are modified based on the number typed into the Adjust Zs by value text box.
