However, I still get a feeling of mismatch between that 3D art and the low berth icon.
I'm thinking the icon should be more like this:
That's just a quick and dirty resize, crop, copy/paste job to get the idea across.
With some additional time to play with the iconography, I decided to try and play with the resizing a little bit more and came up with this:
Ironically, this resize turns the "egg" shape into more of a "rounded crescent moon" shape, since the ellipse is now circularized by the resizing. This changes the
sense of the top-down 3D impression from one of a semi-reclining tube shape into more of a vertical/standing cylinder shape.
However, If I repeat the experiment of putting the low berths into context on a deck plan ... once again "ignoring" the walls for simplicity, but adding hatches to make the "walk space" factors (slightly) more obvious ...
As you can see, the whole thing comes down to being a matter of "packing efficiency" (more or less) of the "pack them in like sardines" variety.
For clarity of documentation purposes, I'm using a 60 pixel by 60 pixel grid (middle of grey line to middle of grey line), which then divides nicely into 1.5m x 1.5m squares (40 pixels per meter) whenever I need to make
precise measurements to scale of things.
The (resized) low berths are 56x40 pixels in size, which leaves a "narrow, side shuffle" space of 40-50cm to squeeze through by sidestepping in tight spaces (so pretty cramped, depending on orientations). The low berth "circle" is 34 pixels diameter at the outer edge, or 0.85m wide at the outer perimeter of the low berth casing. An occupant could have a diameter of up to 30 pixels (0.75m) wide and still (barely) not touch the inside of the low berth casing (and once you're "frozen" for transport you don't need to move much anyway, so...).
For me, that's been a long outstanding gray area in the rules: Does the required equipment tonnage mean just the equipment, or does it include space for a person to maneuver around the equipment? I've always preferred deck plans made with Snapshot-style playability in mind, so I've always added extra tonnage for circulation.
The way I approach this issue, when needing to draw deck plans, is that the "naval architect spreadsheet" calculates the displacement tonnage of the
compartment that stuff has to be put into, rather than the sizing of the "stuff" itself.
For clarity, if I had a design requirement for 15 tons of drives, I would use that 15 ton parameter to determine how large the
compartment ought to be (15*14/1.5/1.5/3=31.111 deck squares). I would then delineate walls that enclose a space of 30-32 squares (for the +/- 10% variance accounting) ... and then get to work filling it up with machinery and work stations and so on.
What I would NOT do is say that I have 15 tons of drives, implement 30-32 deck squares of machinery and THEN "pad out" the compartment with additional walk space around the machinery. In other words, I wouldn't turn an 8x4 machinery space into a 10x6 compartment space in order to be able to "get around" all of the machinery in the center of the compartment.
If you start thinking of "naval architect spreadsheet" tonnage values as being allocations for interior compartment spaces, which then in turn need to be able to accommodate circulation "walk space" within them (rather than the circulation "walk space" being some sort of "extra freebie"), I'm thinking that method is the more intellectually honest approach to the question. For one thing, it means that locations need to "pay" for circulation access to get to them, rather than getting those hallway spaces "for free" and padding out the interior volume somewhat unreasonably (in my opinion, of course). Thinking of tonnages in terms of compartment sizes for stuff also helps to reinforce the "submarine interior" feeling of being in an enclosed life support environment. You shouldn't have these "vast open spaces" here, there and everywhere when interior volume (displacement tonnage) is at a premium. When "circulation walk space" needs to be "paid for" out of the volume budget for compartments, the actual size of "stuff" to put into those compartments gets smaller (because the circulation walk space is consuming a noticeable fraction of the deck area available).
So far, the "best" packing efficiency that I've been able to achieve in my own deck plan research basically comes down to a single central corridor with rooms on either side. So if you've got a 5x5 deck squares "box" shape, you get a 5x1 corridor down the center (1 axis) and 5x2 compartments on either side to fill up with "stuff" however you like. This basically means that 20% of the deck plan area (5 squares out of 25 total) is dedicated to common circulation access, while 80% of the deck plan area gets devoted to whatever you're putting into the side compartments (and if those are staterooms, you need to put a "walkable space" into the center of each stateroom as well).
This is why my (TL=9, so Composite Laminates for bulkheads, which at scale are thicker) 16 ton Stateroom Box of four staterooms "unpowered small craft" in a modular design format looks like this:
I daresay you ought to be able to recognize all of the iconography at work here.
The 4 staterooms are basically identical, just rotated/mirrored to fit each corner. All four have ladder accessed "loft" bunk beds over the sitting area (seating and retractable into the floor table) space below, a lot like
Amtrak passenger train cabins, in order to maximize the efficient use of (limited) compartment volume. That's why there's beds (with ladders) at the top of the image and no beds at the bottom of the image, because the folded down bunk bed makes it difficult to "see" the sitting area underneath in this top down view of the interior (so I omitted the beds in the bottom staterooms for visual clarity). Each stateroom also has closet storage space (beside the entry), an exterior window and a radiation shielding privacy screen (when people are not inclined to look out the window).
The dimensions on the Box are 6.6x5 deck squares (9.9m x 7.5m, from center of bulkhead to center of bulkhead) in a single deck height (3.0m from center of bulkhead to center of bulkhead).
- 9.9*7.5*3/14 = 15.91071429 displacement tons
As you can see, although there are 4 staterooms (16 tons allocation), the volume actually includes 6 "rooms" of space, plus a common access corridor along the centerline (as referenced above). The 2 extra rooms are a Galley/Laundry services room (there's a front loading combination unit washer/dryer beside the cooktop stove in the upper right corner, and the top of the washer/dryer offers additional countertop space for the staging of food preparations) which also includes a Refigerator/Freezer and a Dry Stores "pantry" compartments intended for foodstuffs and other life support consumables.
There is also a holo lounge communal space available for socializing and relaxing in, when people want to be together rather than just separated into their own personal staterooms. Alternatively, the holo lounge can be replaced with a sick bay, containing an autodoc, medical workstation, privacy screen, closet for medical supplies that do not need to be secured and a locker which can store medical supplies that do need to be secured.
Each room is its own pressure compartment, mainly for damage control purposes, but the freshers in the staterooms are using a partition wall and unpressurized sliding door arrangement to separate the hygiene space from the living space inside each stateroom.
The idea with the 16 ton Box form factor is to create a modularized container that can be stacked in arrays and loaded into cargo holds/hangar bays or even externally docked with and towed by other craft as external loads. Additionally, 16 ton Boxes (I've got multiple varieties) can be deployed as housing/habitat/storage spaces for planetary outposts or by Belters who want to have a place to live (other than their small/big working craft). The EVA airlocks serve adequately as "mud rooms" when dealing with external hostile environments (exotic/corrosive/insidious and tainted atmospheres to vacuum baked regolith).
Here's another version of the same 16 ton Box form factor, but with the staterooms done as suites for occupancy by couples (or extravagant social standing persons who need "too much space" for themselves as a luxury).
Double bed with end tables, closet space, separated toilet and sink area ... and the fresher contains both a shower area and a full sized bath for luxurious heated water immersion bathing. The holo lounge is also upgraded with additional greenery vegetation to enhance the feeling of privilege and luxury.
Anyway, these are just examples of what I can get up to when I've got access to good quality transparent background .png images to carve up and "do stuff" with. Not exactly your "standard" Geomorphs practice, but I'm often times working at scales that are smaller/more fine grained than what the "proper" Geomorphs can do, so I'm basically needing to custom fit everything anyway, piece by individual piece.
