the project path and the support file search path. This ensures that revisions
made to the xref are reflected in the current drawing and also makes it pos-
sible for the xref to be found if its path has changed.
For example, 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, AutoCAD looks for xref C at the last location
it was saved in drawing A.

To change an xref path
1 From the Insert menu, choose Xref Manager.
2 In the Xref Manager dialog box, select an external reference.
3 Under Xref Found At, do one of the following:
■ Edit the xref path directly.
■ Choose Browse and then select the xref in its new path.
4 Choose OK.
AutoCAD reloads the xref and then regenerates the drawing with the xref
in place.

Resolve External References That Are Circular
A reference file that contains a sequence of nested references that refers back
to itself is considered a circular reference. For example, if drawing A attaches
drawing B, which attaches drawing C, which attaches drawing A, the refer-
ence sequence A>B>C>A is a circular reference.
If AutoCAD detects a circular reference while attaching an xref, a warning is
displayed asking you if you want to continue. If you respond with yes,
AutoCAD reads in the xref and any nested xrefs to the point where it detects
the circularity. If you respond with no, AutoCAD halts the process and the
xref is not attached.
