Hello Autodesk support team
One of my end user have the problem once they try to open DWG format via AutoCAD2009.
It's shown like attached photo or below massage.
Show Massage >>>
AutoCAD Massage
"Unable to open this drawing."
"It cantain incorrect or corrupted information."
It happen only some DWG file and those DWG file save from AutoCAD version less than 2009.
After that we try to open those files by other 2D software such as draftsight2013 and it can open normally. (no massage, no recovery)
Could you please kindly help to advise for this solution ?
Thanks a lot in advance for your advice.
Best Regards
R.Sopon
