Visual size reference: 1dt and 4dt and average human

Cosmic Mongoose
When I started trying to teach Traveller to new players I had trouble getting the to grasp the displacement ton. Most people aren't very good at visualizing objects and size relations in their head. So I made myself a little visual cheat sheet for future use.

1dt_cube_by_wbyrd-d9ilke7.png


The cube is 2.4x2.4x2.4 meters, (7.8 feet) ( roughly one displacement ton)

Human 1.75 Meters tall ( 5'8 -5'9")

stateroom 10x12x8 ( 3.04x7.3x2.43 meters) 4dt ( not same layout as deck plan rooms just a rough visual size reference.)
 
These are really nice visualizations. One thing to bear in mind is that on most deck plans the actual stateroom itself is assumed to be 3 dtons, with 1 dton devoted to access space and shared facilities.

I am planning to go back and build a stateroom to replace the rough box...As soon as headache my last project gave me subsides...But I is ginning...My last project is done.

Sorry but I was thinking the comparison looks odd; I think there may be a math error , 12ft does not equates to 7.3m I fear.

As I mentioned I am prone to math mistakes..especially when converting from feet to meters....I can use the metric system nicely..unfortunately I still have to grab a calculator to convert.

There are three feet to one metre so;

A little more:

1 meter = 3.280 839 895 feet

I got the meters part right when I did the model...so the actual volume of the blue cube is 4 Dton...just laid out funny...I'll do another version with the proper stateroom measures

I Set the increments in the program to meters, use a volume calculator set to meters, etc...since a Dton is 14 cubic meters..it's when I ran the conversions back to feet/inches. I made the mistake either did the math wrong, or just entered the wrong number.

LOL, I have used meters for my ship measurements since I started drawing them. It's space, it's the future..so I use meters...and then run the conversions back to feet an inches so I have them for the metrically challenged.
 
staeroom_with_overhead_by_wbyrd-d9j52bv.png


alright this image is of a stateroom arranged as a 3x4.5x3 meter room along the lines of Mongoose deckplans with 1.5 meter squares

I inserted a drop ceiling to simulate having an overhead for life support, storage, etc.although it could be placed under the decking below the room.the stateroom has a 2.5 meter drop ceiling. which makes it slightly lower than an average room but still not so low you brush your head on it.

the figure is 1.75 meters tall, maybe a little short...don't say anything he's a bit self conscious. the grid on the lowest pic is a 1 meter grid for reference. I can't get the lousy program to do a 1.5 meter grid ..yet.

The second room is a 6x4x2.3 meter room that is 4dt (3.94 to be exact)....unless my math has failed me again.

and included an overhead shot, to show the footprint of the two. Which lets you see how much of a stateroom is shaved off to be spread around the ship. which takes into account all the miscellaneous tonnages needed for a person to live on a ship.

As soon as I get all the little models of bunks, desks, chairs, freshers, whatnot, worked out i'll decorate it...

As I recall, Traveller custom says that decks are spaced three meters apart, with 2.7 meters of headroom and 0.3 meters occupied by ceiling, overhead machinery, pressure-tight compartmentalization, underfoot machinery, and floor. In US units, that's about 8 feet, 10.3 inches of open space and about 11.8 inches of equipment space, or 9 feet, 10.1 inches deck-to-deck spacing.

Classic Traveller deck plans treated a dton as two 1.5 meter squares with 3 meters deck-to-deck spacing, which works out as 2×1.5×1.5×3 = 13.5 cubic meters, or slightly less than the 14 cubic meter volume that is defined as one dton.

I went off a deck plan illustration for the dimensions..and guessed at the overhead...nice to know I got close on the overhead hieght

I've done raised floors and lowered ceilings, etc, for hiding stuff in 1-dton spaces.
you can put a lot of stuff in a small section under the decks, and overhead....

In an office building it might mostly be dead space, with a few wires and air conditioning ducts...but on a starship I would imagine the dec has a truckload of machinery under it...or over the drop ceiling.

Newt has to have a place to crawl around in, while Hicks is cutting through to get to her. https://www.youtube.com/watch?v=5ohUxs1aLPg

Yes those under deck, and overhead spaces are a GMs best friend at times...

I have a scenario I like to use...I call it "It's in the walls man"

usually it's just something noxious and messy not really harmful...clothes get shewed up in the locker...food packets torn open with foul smelling goo nearby... wiring chewed up.......but ya never know now do ya..all the sudden that ship has way to many places to hide.

you will not believe how fast people break out the suits, and vent the ship....then when it begins to happen again a few weeks later and someone figures out there might be eggs in some of the crawl ways..... :twisted: :twisted: :twisted: <insert maniacal evil laughter>

Anything could be behind those walls. Or doors. Or floor. Or ceiling.

that's why you sleep with a flamer under the pillow...and occasionally find a world with a chlorine atmosphere..open all the hatches and bleach the entire ship...


oh wait maybe that's how they got on board to begin with..they can survive chlorine poisoning, and slip aboard while the hatch was open...
