Geographic Data
If both the host drawing and the external
reference drawing have a geographic
location defined, a new option on the
External References dialog box enables
you to locate the attached xref relative to
the host drawing using Geographic Data.
A similar option for blocks is available in
the Insert dialog box.
Unresolved References
When you open a drawing that has
unresolved references, a new tool helps
identify the missing files.
If you choose Update, AutoCAD LT
opens the External References palette
so you can re-path the missing files. If
you choose Ignore, the warning closes
and takes no action. If you always want
to ignore unresolved references, use the
checkbox at the bottom to stop the warn-
ing from displaying again.
This is a big improvement over previ-
ous versions, when you had to manually
search for missing references by checking
the command line when opening a file,
scouring the drawing for the text strings
identifying unresolved references, or
looking in the External References
palette.
