File menu > XRef Objects > XRef Objects dialog > Create XRef Record From File button > Open File > XRef Merge dialog
The XRef Merge dialog lets you choose which objects to add as XRef objects to the scene. This behaves similarly to the Merge command. Controls in this dialog are similar to those in the Select Objects dialog.
The Merge dialog lets you load and save influences with or without their dependents. In many cases, objects should be referenced
with their influences, but the display only makes you aware of the relationships, it does not force you to externally reference
them.
When you select an item in the list window and click Influences, the object’s influences are selected in the list window.
When you select an item in the list window and Display Influences is on, the object’s influences are shown in blue in the
list window. When you select an item in the list window and Select Influences is on, the object’s influences are also selected
in the list window.

Objects are listed according to the current Sort and List Types selections.
Influences—When you select an object in the list window and then click the Influences button, the selected object's influences are highlighted
as well.
All, None, and Invert—These buttons alter the pattern of selection in the list window.
Display Influences—When this is on and you select an item in the list window, all of its influences are shown in blue. If you want to highlight
these influences, click Influences.
When this is on and you select an item in the list window, all of its influences are highlighted as well.
