I recently purchased a home, and have no blueprints for it. I would like to be able to create a model of the house and systems on my computer so that I can easily reference it. I'd like to map out electrical circuits and fixtures, plumbing, doors, walls, etc. Being able to associate appropriate specs to a fixture (e.g. watts consumed, flow rate, etc) would be great.

Is there a cheap/free solution for me? I don't really care about 3D rendering but layers would be nice, and I'm willing to install Linux on a partition if that is what it takes :)

I think slashdot is broken.

I like to be able to go back to a previous topic and perhaps continue discusions. I can't seem to find my post list anymore. Is this some ploy to goad subscribers?

what the hell is this for?
