420 Chapter 20: Managing Scenes and Projects
This works b est if b oth the parent object and the
XRef scene have their pivot points positioned
at 0,0,0. You can do this by using Transform
Type-In to move the parent object.
If the XRef scene was created a large distance
from the origin, you can run into a problem. As
you try to scale, the XRef scene will move away
from the center. To counteract this problem,
you can create a second dummy object centered
over the XRef scene. Then select a nd link the
original dummy object to the centered dummy
object. You can then scale the centered dummy
and the XRef will not move toward or away
from the origin.
An alternative metho d for scale problems is to
use t he
Rescale World Units Utility (page 2–49)
on the original file.

File menu > XRef Scene > XRef Scenes dialog
The XRef Scenes dialog lets you add and remove
XRef scenes. It also gives you tools to control
the display of the XRef scene, options to ignore
various components of the scene, and the ability
to bind to a parent object so you can scale, rotate,
or move the XRef scene.
Accessin g X R ef Scenes
Although XRefs are inaccessible “boxes” in the
scene, they can b e accessed in v arious ways.
• Cameras and lights in the XRef scenes can be
accessed in the Viewports list and assigned to
viewports in the current scene.
• Objects from the XRef scenes are included in
the Summary Info dialog.
Nesti ng XR ef S cenes
XRef scenes can be nested. That 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.
Interfa ce
XRef Files list—Displays all XRef scenes in the
current scene, and lets you select them for
operations. XRefs that have been disabled (by
turning off Enabled) are listed in gray rather than
black. If an XRef is listed in red, that means its fi le
could not be loaded. Either the file is corrupted,
or the path is not pointing to the correct directory
or file name.
