Introduction -. On March 13, 2013, the Centers for Medicare & Medicaid Services (CMS) concurrently issued CMS Ruling Number CMS-1455-R (the Administratorâs Ruling) and a proposed rule, âPart B Inpatient Billing in Hospitalsâ (the Proposed Rule).
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.
1 To open the file as read-only, select Open as read-only. 2  Select a file, then click Open.  If you import a DXF/DWG file that has XREFs, eDrawings tries to automatically resolve the XREF. If the XREF cannot be resolved, the Resolve XRef dialog box appears.
