I am using Mechanical 2013. Another dept is using Civ 3D. It has become apparent to me that when Civ 3D users open/save regular AutoCAD dwgs the proxy objects are throwing a monkey wrench in the dwgs when I go back in the dwg with standard Autocad. the file just processes and processes AND PROCESSes.

Please tell me the files can be restored to a pre-CIV3D state. I am a 15 year user of AutoCAD so it’s not a purge or audit. It’s absolutely a compatibility issue with the proxy objects in CIV 3d file.
