External References
The selection of externally referenced files has been enhanced in AutoCAD LT 2011. When you select a
reference object in the drawing (xrefs, images, DWF
TM
, DGN, PDF, data extraction tables), the
corresponding reference is selected in the External References palette. Similarly, if you select file
references from the External References palette, the references are highlighted (but not selected) in the
drawing, assuming they are visible in the current view. You can control this behavior with the new
ERHIGHLIGHT system variable.

Scale Lists
Scale list functionality has been enhanced in AutoCAD LT 2011 to store a customizable default list of
annotation scales in the fixed profile of the registry. You can use the default scale list to define a
customized list of scales that automatically displays in all your drawings. A scale list is still maintained in
the drawing, but you can easily reset the scale list in the drawing to the default list of scales (metric or
imperial) defined in the registry. When the scale list in a drawing is reset, AutoCAD LT purges the unused
scales in the drawing and then merges in the customized list of scales from the registry into the drawing.
You can customize the Default Scale List from the User Preferences Tab of the Options dialog box. You
can still edit the scale list stored in the drawing by accessing the scale control on the Status bar or with
the SCALELISTEDIT command.
