XRef Scenes Dialog 411
This works best if both the parent object and the
XRef scene have their pivot points positioned
near the scene’s origin (0,0,0).
If the XRef scene was created a large distance
from the origin, you can run into a problem. As
you scale the parent object, the XRef scene will
move away from the center . To counteract this
problem, you can create a second parent object
centered over the XRef scene. Then select and
link the ori ginal parent object to the centered
parentobject.Youcanthenscalethecentered
parent object and the XRef will not move
toward or away from the origin and use the
original parent object to move the externally
referenced scene.
An alternative metho d for sc ale problems is to
use the Rescale World Units Utility (page 2–53)
on the original file.

Nesti ng XR ef S cenes
XRef scenes can be nested . T h at is, an XRef scene
can contain other XRef scenes, which can in turn
contain other XRef scenes.
Note: For a nested XRef scene to update
automatically , all of its parent scene files (files that
include it as an XRef) must have Auto Update
turned on.
