We currently run on 2007 Autocad LT (sad I know) and have a laptop with the latest Autocad. We used Trueview converter to save down files from laptop and now we cannot detach xrefs and all xrefs read as blocks in our files on 2007 Autocad LT. When we update an xref file; it does not update in other files which I'm assuming because it's a block in the original. Thanks in advance for your help!!
