Good day.
I have old project with drawings. Using "Document Manager" i try to edit project's dwgs and some of them are opened with mistake - piping doesn't load and in console AutoCAD writes "stringp nil;". This situation happens if i work on machine with Windows 7, Bentley AutoPlant V8i SS3 and AutoCAD 2012. Using WinXP and AutoCAD 2009 (i don't know version of Bentley) piping loads normal.
Can i convert drawing with mistake from old version AutoPlant to new version?
