I seem to be having an issue with Autocad 2012. I noticed it when I first installed it but didn't need to use it until now.
When I want to attach an Xref, I open the Xref dialog box, and click on the 'DWG' icon I selected, I keep getting this error:
This file cannot be opened.
The problem can be caused by several things:
-The data in the file is corrupt
- The file is an earlier format that is no longer supported
- The file format is not supported
Try to obtain a better copy of the file, recreate the file using different settings, or convert the file to a supported file format.
This happens with any xref file type selected and when attaching an Xref using another method. The only time Xref does work is when I use '-xref' command and attach it from the command line. The file path length is short, so I crossed that solution out.
