For something like AutoCad My preference would be at least 8 GB ram and a MacBook Pro with the discrete GPU in addition to the Intel HD integrated GPU. Depending on the size of the work, that kind of software can make heavy demands on the graphic processor and can use a lot of memory.

You are welcome...another advantage of the Pro over the Air is being able to add ram after purchase if it is needed. The Air cannot be upgraded at all since the ram is ordered to the logic board.
