This toggle restricts the visible contents of the Attribute Editor to features that are currently selected with the digitizer.

New Attribute

Press the New attribute button to add new attribute to all features currently loaded in the table.

Type a name for the attribute in the Attribute Name box, or choose from the list of attributes recently added in the digitizer tool.

At the bottom of the dialog, choose from the following duplicate attribute detection options:

  • Do not update any features - If the attribute name already exists for any of the loaded features, the new attribute will not be added. This option prevents accidentally replacing attribute values.
  • Add it to features that don't have it or where it is empty - The specified value will be assigned to the feature only if the attribute value is empty or the attribute does not exist.
  • Add it to features to don't have it; update features that do - All features in the current list will be updated with the new attribute value, replacing any other values that might exist for that attribute.
