From publisher blurb: Sci-Fi Starship Deck Plans #4 is a set of five color deck plan maps perfect for interior map designs for your interstellar spacecraft adventure. Some areas of 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. Two types of deck maps are included (with and without square grid) but you can arrange these in any order to make your ship have as many decks as you need for your design.
