I have made a barter deal with a cabinet maker/carpenter to custom build my very small computer room a desk that covers the entire room, integrates my primary and secondary systems, my wife's work and Graphics machine, my file server, space for a PC to be worked on, and a small 15 inch monitor for the one I am working on. Not to mention lots of book/junk shelf space and tons of drawers for my wife's oil, pastels, sculpey, etc.

Here is the challenge, I have been doing the design work so far all in my head but my RAM for details is running low, so I started graph papering it.

Short of the full AutoCAD, anyone know of an app that would let me do this, provided visualization, a piece list etc?
