the path of the missing xref. You can use the XREF Path option to update or
correct the path.
Along with error messages being displayed at the Command window, a task
dialog box might be displayed which allows you to ignore all missing reference
files or update their locations. You can use the External References paletteto
update the locations of the unresolved references.
One way to avoid these errors is to be sure that when you give other people
files that have xrefs attached, you also give them all the referenced files.
Change Nested Xref Paths
When the drawing is reopened and the nested xref is loaded, the program
attempts to find the xref in the original xref path first. If the xref is not found,
the following search is initiated in the order shown:
Current folder of the host drawing
Project search paths defined on the Files tab in the Options dialog box and
in the PROJECTNAME system variable
Support search paths defined on the Files tab in the Options dialog box
Start In folder specified in the Microsoft
®
Windows
®
application shortcut
This ensures that revisions made to the xref are reflected in the current drawing
and also makes it possible for the xref to be found if its path has changed.
For example, suppose that the xref tree of the current drawing A is A>B>C,
and the owner of drawing B changes the path of xref C to point to C1.dwg.
When drawing A is reopened, it reflects the path change in drawing B and
displays C1.dwg. However, if C1.dwg is not found, the program looks for xref
C at the last location it was saved in drawing A.
