Autodesk programmers should be ashamed of themselves. I loaded 2013 on Monday and I have already switched back to 2012. This has to be the shortest amount of time I have used a new release. NONE of the bugs from 2012 or 2011 for that matter have been fixed, so why load 2013??? It has taken me a year to get 2012 to run pretty good, and I feel like I'm back in April of 2011 again.
It seems like most of the "upgrades" are for the 3D world, could Autodesk provide some numbers as to number of users of 3D compared to 2D. Make our subscription worth something for once.
FIX PREVIOUS ERRORS PRIOR TO RELEASING A NEW VERSION!
Why not save some money and stop upgrading?
You might participate here http://beta.autodesk.com and if you never see any value worth the upgrade - your CAD expense is over (at least until 2012 is no longer supported or until your computer dies).
Maybe Autodesk should be ashamed...
...but I would not want to explain to the boss why he/she continued to pay for a tool for my use of no value.
