Anyone have a map of an interior of a large spaceship for sample?

I'd like to take a look at what one might look like, so that I can try my hand at drawing my own. I'm thinking 'prison ship' meant to hold thousands of prisoners. Has a large supply bay, along with cryo chambers, 3d printing facility (like a mini factory), a big ol' reactor for the thrusters and FTL, and many computer terminals. Intended for a dystopia turned planetary adventure game when the ship crash lands - players and NPCs will still be able to explore the fully intact 'wreck', because it was a soft landing making a big divot in a desert (though the FTL and engines no longer work). Nav AI intended to land on a habitable planet for humans, so picked the one it crashed on half at random when it discovered the engine was failing (long story there).

Thank you!
