How can you tell what version of AutoCAD a file is from?

[Anonymous]

Hello all, Seems there's no good resource for MDT customization so I'll post my question here (and everywhere else I can find). How can you tell if a DWG is a MDT file, a Mechanical file or just a plain AutoCAD vanilla file? The ADN told me to look for unique libraries in the file but I don't buy it...the Autodesk Batch Drawing Converter can identify any file I throw at it so I know there's a quick and easy method. Any ideas? Jim Dowthwaite Please reply to jdowthwaite@netstream.ca if possible

Try examining the first half-dozen bytes or so in the drawing. For example, opening an AutoCAD 2002 drawing in a hex editor I can see "AC1015".

Well, I've never had to worry about that. Just taking a quick look at the file header I see a difference in byte 11 from plain AutoCAD to the verticals. This might be a subversion indicator or something like it. For example, all plain 2002 files have a 0D value in byte 11, but ADT 3 files have a 0B value But of course, I'm just making a very wild guess here. -- Saludos, Ing.
