If you're not considering parametrics or even 3D, I don't see the point of buying Inventor, as opposed to bare AutoCAD 2014, or AutoCAD LT, or even Draftsight (for which I think there may be a small fee for commercial use; the license for the free version specifically says "Non-Commercial").
Solidworks is a wonderful tool for solid modeling, but I find its drawing editor counter-intuitive and irritating. It would be less irritating if you could turn off most of the automatic behaviors that try to anticipate your next move. It's like having an industrious but incompetent personal assistant who keeps running interference for you, and tripping you while doing it.
