AutoCAD Version

You can if you apply the method described here:

https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/How-to-find-which-version-of-AutoCAD-was-used-to-create-save-a-DWG.html

by reading it as a text file and mapping the version values into the correct dwg version.

Just make sure you use the schema attributes in the text reader to have the original dwg name.

Hoe this helps.

Thanks alot... Nice trick

AutoCAD Reader: Successfully opened the 'Release2010' AutoCAD file 

A less known but very useful parameter when reading DWG files is "Read Drawing System Variables":

Then you get an null feature called autocad_info which holds many useful attributes, like DWG version.
