Enhancements in the AutoCAD 2018 release help reduce the problems created by broken
reference paths.
When you attach an external file to an AutoCAD drawing, the default path type is now set
to Relative path instead of Full path. If Relative path isn’t your preferred path type, you
can use the new REFPATHTYPE system variable to modify the default reference path type.
Set the value to 0 for No path, 1 for Relative path, or 2 for Full path.
In previous releases of AutoCAD, you cannot assign a relative path to a reference file
when the host drawing is unnamed (not saved). In AutoCAD 2018, you are able to assign a
relative path for a file even when the host drawing is unnamed. If you select the reference
file in the External References palette, the Saved Path column displays a full path with an
asterisk prefix to indicate that a change will take place when you save the host drawing. A
property in the Details pane also indicates that the reference file is pending a relative
path.
