AutoCAD stopped using PFB fonts a very long time ago: replace these in both your source and destination files now (STYLE command) or live with the prompts forever.<BR />2. You have a nested block in your selection called _ArchTick, or your files were at some point saved in a newer version (2013 is different from 2012, a commone issue when you mix versions like that regardless of how you save the DWG file). Using -EXPORTTOAUTOCAD command in 2013 should fix the files for 2012 users. In both 2012 and 2013 remember to also go to OPTIONS command's OPEN AND SAVE tab's and uncheck the two MAINTAIN... boxes under the save as pulldown.
