Good Afternoon! I have a student version of AutoCAD for MAC that I
have been using. I was using a trial version of 2016 and saved many
of those drawings down to 2010, but am not able to opening them with
the student version of AutoCAD 2011 that I have. Is there a reason for
this? Would a version this old be considered obsolete at this point?
If so, what are some of my options for upgrading? Thank you!
