I do deckplans sometimes in Illustrator because I have a dislike for most official deckplans. I think they tend to be either too complicated or too moronic (we don't need to go to the refresher, honest).
Anyway,
here is a deckplan for a YT-1930
, I was making it for my group and I thought someone else might be interested in how it turned out. (Its vectored, so you can zoom in and out as much as you want).
(Dropboxes viewer screws up the drop shadow effect. Looks best to open it with a dedicated viewer.)
