The time spent on a learning curve is equal to or greater than the cabinet build. Free design software from Parker T-slot or FrameDesigner don't work very well in my opinion.
Paying for AutoCad is out of the question. I've seen some CAD programs, both free and some very expensive. The cost of the extrusions and the fittings, combined with the lack of a local supplier that would allow going in and loading a cart has me thinking of the importance of dialing in a design and materials list up front. I am getting close to having to start the design of some cabinets using T-slot/8020 extrusions.
