I submit the following for your consideration. I recently upgraded from AutoCAD 2005 to 2008. Using 2005 I was able to convert my .dwgfiles to .pdf and retain the same basic file name as the CAD drawing. Using 2008 the file name is now appended with "Model (1)", so if I start with "Drawing 1.dwg", I end up with "Drawing 1 Model (1).pdf". I currently have both versions of AutoCAD on my PC (Window XP Pro) and they will produce two different results when converting the same file. I am using Acrobat 3D 8.1.0. This same problem plagued me for years in previous versions of CAD and I thought it had finally been resolved. Also, when I first began using AutoCAD 2005, I was still using Acrobat 6 Pro, again there were no problems with the file name, nothing was appended. I did not add any scripts or VBA routines to AutoCAD 2005, it simply worked fine. Does anyone know if there is a preference/ switch either in AutoCAD or Acrobat to fix this problem? In previous years I had to edit each conversion by hand until AutoCAD 2005 "fixed" the problem, I'd rather not have to do that again. Any help would be appreciated, thanks.
