If a drawing is saved in a DXF format then opened with an ASCII text editor the header information will tell the user what version of AutoCAD the drawing was saved to.  So, for example, if you opened the file and looked for the entry $ACADVER and saw AC1024 this would mean the drawing was saved to the AutoCAD 2010 file format. 

To my knowledge there is no "license" information contained within the file.  For that information one would have to look in the Window's Registry.  I don't know if the information in the DXF file would also tell someone whether or not an educational version was used. 

Now at one time there was a lisp routine available that would warn users when they were about to open a drawing that was created with an educational version of the program but I don't know if it is still available or if it would pick up on drawings saved in versions of AutoCAD that no longer included the educational banner.  Do you understand all that?

Update: I found that lisp routine but in the description it clearly states the last supported platform the product supported was AutoCAD 2002.

Hi!

Do you know if Autodesk product do store licensing info in th files you created with them? I do not want to get my company into trouble. *I definitely mean that if at home I am using student version to finish up something, but these days with the regular one you can remove the watermark... but would that make it untraceable that you used a student version to create it originally...etc?
