Welcome to the Guild Rufus! Well I'm not sure if there are any star-ship related tutorials here or not. There certainly might be, but I haven't ever needed to create a map of one before so I've never looked. You might check out the Sci-fi section though to see if you can find examples of what you are interested in, and then try contacting the artist to esquire how they did it. Also, have a browse around the tutorials section.
