From publisher blurb:
Sci-Fi Starship Deck Plans #1 is a generic set of deck plan maps perfect for interior map designs for your favorite saucer or cylinder shaped interstellar spacecraft. These maps are 300 dpi png format black and white images in two versions one with a grid and one without one. The deck plan maps have been left deliberately blank so that you can add your own notations or import your own room furnishing icons. The original concept of these maps was for each grid square to equal two meters but you can rescale that to fit any size you like for your own projects. Five deck maps are included but you can arrange these in any order to make your ship have as many decks as you need for your design. You can also use any image program to flip the orientation of the maps to add even greater diversity to the possible combinations.
