Topics covered in this Lesson: XRefs (External Reference Files in AutoCAD) An XRef is an âexternal reference' to another AutoCAD drawing file. One file can reference many other files and display them as if they were one. These are used in larger projects for many reasons: They keep the file sizes down.
Notification of Attached Xrefs. An xref icon is displayed in the lower-right corner of the application window (the status bar tray) when xrefs are attached to the drawing. When one or more xrefs are not found or if any of the xrefs need reloading, an exclamation point is added to the Xref icon.
