Attach, Update, and Bind External References | 667
A drawing can be attached as an xref to multiple drawings at the same time.
Conversely, multiple drawings can be attached as external references to a
single drawing.
The saved path used to locate the xref can be an absolute (fully specified)
path, a relative (partially specified) path, or no path.
If an xref contains any variable block attributes, AutoCAD ignores them.
Note Xrefs must be model space objects. They can be attached at any scale,
location, and rotation.
Notification of Attached Xrefs
An xref icon is displayed in the lower-right corner of the application window
(the status bar tray) when xrefs are attached to the drawing.
When one or more xrefs are not found or if any of the xrefs need reloading,
an exclamation point is added to the Xref icon. If you click the Xref icon, the
Xref Manager is displayed.
Tools for Attaching Xrefs
To attach an xref, use
XREF to display the Xref Manager or use XATTACH.
You can also use DesignCenter
™ to attach xrefs to a drawing. Use Design-
Center for simple attachments, previewing external references and their
descriptions, and quick placement by dragging.
You can attach an xref by dragging it from DesignCenter or by clicking
Attach as Xref on the shorcut menu.
Visibility, Color, and Linetypes
You can control the visibility, color, linetype, and other properties of an xref's
layers and make these changes temporary or permanent. If the
VISRETAIN
system variable is set to 0, these changes apply only to the current drawing
session. They are discarded when you end the drawing session, or when you
reload or detach the xref.
