The Edit Attribute Value window, called by the Set Value action on the Edit Attributes page, allows you to modify any of the editable displayed attributes, except location, of objects selected or the action. Attribute values are only editable for checked out objects. If you select both checked-out and checked-in objects, and then click Set Value, the Edit Attribute Value window is opened. However, changes made in it only apply to the selected objects that have been checked out.

Similarly, if you select a family table instance, and the instance has a generic that is not checked out in the current workspace, then the Edit Attribute Value window is launched. However, changes made in it only apply to the valid set of objects.

In the Edit Attribute Value window, the Set menu contains a list of object attributes currently displayed in the columns of the Edit Attributes page. Depending on the attribute selected in the Set drop-down menu, the To field presents a menu (for list-specified values) or input panel (for range-delimited values). Any default value for the attribute is displayed when the Set selection is first made.
