Use feature class forms to edit, view, and analyze feature data stored in an industry model . The Industry Model explorer shows the data model feature classes and related feature class information you can edit with feature class forms.
Feature Form Toolbar
The Feature Class Form Toolbar appears at the bottom of each form. Move your cursor over an icon to see its tooltip. Some icons are visible only under certain conditions.
A symbol at the far left of the title bar indicates the type of feature class and the name of the feature class.
Master-Detail
A
master-detail form
consists of a master pane and a detail pane. Using master-detail, you can set the filter on every input field of the master and detail pane. After you have set the filter, you can execute the filter by clicking Filter. 
Without master-detail, you can query related records. This opens all related records that belong to the current record, for example, all symbols belonging to a boundary point. You can display these records in a separate pane.
By default, the master-detail panes are not displayed.
Auto Highlight
Use the Auto Highlight option to highlight a feature when you move a record. There is no need to click Highlight. You can activate Auto Highlight for each form.
Auto Highlight is active until you switch it off or until you close the application. This option is only available for feature classes with geometry (GEOM column).
