If you purchased 2015 for $4200 (4195) then you have a new perpetual (permanent) license, so you can use AutoCAD2015 for as long as you want without paying Autodesk another cent.&nbsp; If you anticipate a need to update to a newer version within the next few years, then add a $545 yearly maintenance subscription to your perpetual license before Feb 2016, and you'll be able to keep your perpetual license so you can update to the newest version anytime you wish.</P> <P>&nbsp;</P> <P>Just to be clear, perpetual license do not expire on Feb 2016, it's just that you won't be able to purchase a new perpetual license... If you have one, it will still last forever, and you can even renew it, you just won't be able to start a new one after Feb 2016.</P> <P>&nbsp;</P> Mon, 16 Mar 2015 21:00:00 GMT nestly2 2015-03-16T21:00:00Z
