Help with Ship drawings

[dragonlady]

I'm starting out new with Traveller Ship designs (Classic and Mongoose), in CC3. I have Cosmo Cartographer add on, but I need some help a little.

For each 5x5 grid on my deck plan, how does that equate to a unit (tonnage) in my ship design?

Thanks for help on this, there are some great design on here and I'm ready to do some of my own. Thanks

Each square in CT and MgT is considered 1.5 meters per side. By default, these are considered to be 3 meters tall for deck plans. Each such square equates to 1/2 of a displacement ton.

Why 5x5 grid? Do you mean 5 meters x 5 meters? Not the usual grid for CT or MgT. Or do you mean 5 standard squares by 5 standard squares? In which case that's 25 squares or 12.5 displacement tons.

Aha, after drilling through LOTS of posts I found this:

LBB 2 page 21 under Deck Plans:

"Deck Plans: If the referee or the designer should feel that detailed deck plans for a ship are required, then they may be drawn up using square grid graph paper. The preferred scale for the interior should be 1.5 meters per square, with the space between decks put at about 3.0 meters. One ton of ship displacement equals approximately 14 cubic meters. Therefore one ton equals about two squares of deck space."

Might not have been in the first edition, that's from the second, c1981.

I was thinking 5x5 because I was coming from a d20 game world which each square is 5ft by 5ft, and I had forgotten that Traveller tends to be in meters.

So the short answer seems to be to do 2 squares per ton of designation.
Has this changed in the intervening years (since 1981?).

If not then this is the answer I sought!

Thanks!

If you want a place to start I wrote a piece about creating Traveller deckplans with CC2Pro:

Maybe you'll find it useful.

Robyn- use 2 5x5 grids per ton. roughly 50%-75% of non-cargo, non-fuel component tonnages should be components, and 25-50% should be access space.

The 10'x10' Cosmographer staterooms are roughly 2 Tons, of the 4 for a large stateroom; the other 4 squares should be common space and hallways.

For the others: those are 5'x5' squares; CC2 & CC3 default to English traditional measures.

explanation:
A Displacement Ton is almost 500 cubic feet*. a 5x5 square is 25 square feet. Given a 10' deck to deck, that's 2 squares per Td.

But since the Dt is shorter than 500ft³, 9.9 feet (roughly 9'10.8") for the CT/TNE/T4/T20 Td and 9.2 feet (9' 2.4") for the MT and MGT Td.

* 1m³ is 35.3147 ft³; a Td is either 13.5m³ or 14m³. so 459 to 495ft³. The GURPS Traveller Td is defined as 500ft³. (Yet again, GT is wrong. )

Oh sure, give me homework!!



Seriously, that is a good place to start, thanks!

Depending on how accurate you want to be, watch out for deck height. The original drawings of the 100dT scoutship were notorious for that - thanks to the radical wedge shape, some of the 'rooms' were only a metre or so high. Try to make sure your accommodation will fit in the side and end elevations as well as the plan view. No need to draw all that out, but if you are a seeker of authenticity it might be worth a quick sketch to make sure.
Be sure to post some deckplans when they're done.

Yes, the deck plans as printed are normally two squares per displacement ton, and that actually works out well for miniatures gaming, as the typical human-sized entity will fit nicely into one square (print out the plans to the correct scale, naturally...).

There are some tools that may be useful for doing plans or mockups that don't actually accommodate the 1sq=1.5m standard; by knowing the standard, though, and knowing what the tool's scale is, you can still do reasonable work with those tools. For example, if you were to use The Sims 2 for doing interiors of ships or buildings, the standard build mode square is a good approximation for 2.5ft, so you can use eight of those squares for one displacement ton (using the GURPS approximation of 500 cubic feet per displacement ton, and assuming deck height at ten feet).

Yeah, GT got some things wrong (I'm looking at YOU, "20% off for streamlining" rule). Just as every other version did. This one is within the 10% 'slop', though.

I'd stick with 1 square for 1/2 dTon. If you use 5 squares per half ton you'll have a huge number of squares and the scaling to print will probably be pretty crappy, plus the pre-made images for floor hatches and everything all look wrong.
