I'm not sure if anyone sells one with sheet lay outs and details ect. We draw our own using SmartDraw http://www.smartdraw.com/specials/ppc/smartdraw.htm?id=104867. Once you get use to it, it works pretty well. Scale can be changed and ect. What we did was make some different scale templates and go from there. Also make templates for units, tapered ISO, and anything else on the roof and you can just copy and paste them where they need to go.
It has a free trial and you will probably use most of the trial up trying to figure it out. I'm sure some where someone sells one, it may be more like a rental program like some of the suppliers use for tapered plans and such.
