Welcome to the Autodesk/AutoCAD forums !
Yesterday I would say MAP 2013 + SP 2.1
Today we have MAP 2014 + SP 1 : no experience about MAP 2014 + SP 1
because it's too NEW but I hope it will be OK ...
Waiting for other opinions ...
I am upgrading from 2010 to 2011, 2012, 2013
Are you... what?
You may legally upgrade only to the last release, sir, unless I got muzzy...
MAP 2012 wasn't so bad especially with the SP 2 installed !
I have ALL versions of MAP 201X on many PCs ...
( And a few MAP 2004 / 2006 / 2007 on some old PCs )
My preferred MAP are : MAP 2011 + SP1 + SP2 and MAP 2013 + SP 2.1
But I think that I will use more now MAP 2014 + SP1 ...
The most important, I hope that you will use a MAP 201X 64 bits on a PC (Win Seven please)
with a minimum of 8 Gb ?
