There is no question that making Wh40k ship deck plans are both ambiseous and slightly insane.
While there is a few good maps out there, and indeed many great topics on this very forum about, what ought to be on a spaceship, there are virtually no detailed deck plans. Obviously that may have something to do with the fact that drawing a 10km long spaceship with 100+ levels and a maze of hallways are a daunting task indeed.
There are in fact only 2 ways to make a "good" visual repensentasion of a ship layout.
1, make is small, a gunboat, minor shuttles or very small ships
2, Make a outline of the ship and point to whats where. Theres the bridge, the Apothecarium ex ex.
I went for option1 and made a 3 deck detailed plan over a vessel for about 40 personel. The idia is to test my skills and to use it as a small endeavour vessel, sent with a private security force to do some stuff. As is it the resolution is VERY high as it is a 13MB PNG and I also have PDF versions on filestorage should anyone care.
I will make all 3 decks and more as they come availevle on my Deviantart and maybe through dropbox (on requet only).
I relice there is a number of things missing, Lifesupport, manufactorium, cogicators systems, comminication, gun decks, apothecarium, secure vaults, prison fasilities, view dome, cathedral or at least a shrine and much more.
Keep in mind this is the first, already i am working on a ship that will have 3 subdecks,6 maindecks and a hull, and is 12-15 times bigger (this one was mapped in 300x150, other is in 1000x400 (meters)
Look at it on my Deviantart and tell me what you thing on detail lvl, add to the list of facility there ought to be and I hope others will benefit from my work.
Ps, makeing all 3 decks took about 12 hours. Posting link twise in cas i messed up, since I cant Paste it in here! (wft)
PPS for thouse that dont know deviantart, I remark that you shoul look to the UPPER right of picture and press the download to get thw 7000x5000 picel version.
