Building on the popular DWG Compare tool from previous releases, AutoCAD 2021 introduced Xref Compare. When an external reference (Xref) file changes, AutoCAD automatically notifies the user. The Xref Compare tool allows the user to view the precise modifications made to the referenced drawing directly within the context of their current workspace, preventing design oversight errors.
