The Linked XForm mo difier links the transforms
for any object or sub-object selection to a nother
object, called the control object. The control
object’s motion, rotation, and/or scale transforms
are passed onto the object or sub-object select ion.
Using Link ed XFor m
Linked XForm connects any geometry it receives
from the st ack to another object, which is called
the control object. Its sing le control simply picks
the control object. To use this modifier, you must
have at least two objects in your scene.
