Mac Drawing App

[Shu15]

Hey all, is there an app for Mac that lets you draw "blueprints" and other stuff for projects that you might have? The reason is, I'm trying to make a home-made pedal board for my effects, so I need to get it out on paper in order to start making it. I'd prefer it to be free, too. Thanks!

Maybe Omni has something for you: http://www.omnigroup.com/ .

Thank you very much, that was close, but no cigar. Any other ideas anyone?
