List Unlinked Display Objects
An unlinked object is a display object not linked to a record in the power system model (model object).
The existence of unlinked display objects on a oneline diagram can be misleading because they have
zero flows and zero bus voltages associated with them. See Object Relationships for more information.
Go to the Onelines ribbon tab, then on the Active ribbon group choose List Display > Unlinked
Display Objects from the main menu in Edit Mode to identify unlinked objects.
Total Number of Unlinked Display Objects

Unlinked Display Objects Dialog
Indicates the total number of unlinked objects on the display. Ideally, this number should be zero. If
nonzero, the unlinked objects are identified in the table by type, screen location, and zoom range
over which the object is visible.
Delete Unlinked Objects
Click on this button to permanently remove all unlinked objects from the display. Exercise this option
carefully. Generally, you will want to do this either when you have substantially modified a power
flow case, such as by creating an equivalent, or when you are using the oneline with a new power
system case.
View Options for Highlighting Unlinked Objects on the Oneline
Click on this button will open the Grid/Highlight Unlinked Objects tab of the Oneline Display Options
Dialog.
Type, X/Y Location
The remainder of the display shows the type, location, identification, layer, applicable zoom level,
anchored property, and font size for each unlinked object. This table is a type of Case Information
Display and thus behaves similarly to all other case information displays. Right-click on a record in
this table to invoke the local menu. Select Pan to Object on Open Onelines to locate and select
the unlinked object on the oneline diagram.
