3D Titanic drawing

I'm drawing Titanic in 3D. There were free 3D drawings already available on 3Dwarehouse, but they were incomplete and not well proportioned. I felt I really wanted to have a thorough knowledge of Titanic's layout, so I began tackling it for myself. Here is the beginning of the generator room on the lowest level right behind the turbine room. Until I drew this, I really had no idea how this would look. I will still be adding shaft bearing mounts, raised walkways, watertight doors, and so on.

Here I've added the double-ended scotch boilers.

The hull is a complex shape, and I've been hard at work ensuring it's shape is accurate. I haven't found adequate drawings of the front view, so the hull is incomplete below the waterline at the bow until I receive Dr. Robert Hahn's drawings in the mail.

Every little bit helps! I actually already knew that the entire lower level is on a raised floor above the tank top. I still have to check to see if every raised floor from the electrical room to the turbine and reciprocating rooms, as well as all boiler rooms, are raised to the same level for the length of the ship. This morning, I also purchased the new deck plans and elevation that was published by the Titanic: Honour And Glory team. They've painstakingly tried to separate the Titanic and Olympic differences, since prior deck plans were actually based off the Olympic. Here's a screenie of my progress in the electrical room from the perspective from the rear, at center catwalk height:

Titanic - Olympic’s machinery shows the view the other way, and the steps up to the control room.. " The port main generating set in the electric control room " its important because one can see a person by the steps, and scale it... so if one says a person in boots was 6ft high, and 2 feet wide max.. one has a referenced scale.. it tells one a lot of unknown dimensions... its the only way into the control room... and the only exits were the watertight door, on the starboard side, or possibly the emergency exits from the tunnel over the prop shafts at the far end port side of your image..

I'm enjoying these drawings very much.

The generator dynamos, compared with a photo taken from the same viewpoint, as well as the switch room located on the orlop deck, but open to the generator room down below. The red flooring is the Litosilo that was used to coat each and every deck of the ship. Whether or not it's the same in the switch room, I don't know, but it's like that until I can confirm otherwise.

Great Stuff Freddie,
beware how you place things, there was a gap between the back of the lever switch panels and there were railings at the top of the steps up - probably at the open edge over the generators, since it was required to access the lever panel from its back, for installation and servicing... the gap can be seen in images of the switch room.. , i did scale it, based on the rooms known height of 8 foot and the size of the slate panels..and the fuse sizes , and the various meters and throw switches available then.. you can see my scaling here... Electricity During Sinking the best i could do, based on the rooms known height, and how many panels there were, and the deck plans, all four main generators ran into those two lever switch boxes, with space in the room for another , because there was the possibility of two more generators, which was never needed.. the emergency generator supply came into the panel at the cigarette store port end of the room... behind the main in your image, and the circuit protection and connection to the main bus bars = for those, was at that end, and your scaling for that i agree with.. not more than 5 feet between the panel and the main generator boxes, but enough space to get past the levers in the down position.. and to pull them down or push them up..

Yes, I did leave a service space behind the breaker panel. The breakers themselves on the top of the panel still need to be drawn, I don’t have a whole lot to go on so I’m going to be eyeballing them from two photos that show them in reasonable detail, so it’ll be ’close enough’ but still look believable.

Railings are still to come, I have six catwalk ladders to complete still, once they’re done I’ll get the railings.

Oh and the ammeters on top of the switch control panel still need to get done.

Hello, railings! And center shaft bearings!

Progress update time! I received Dr. Robert Hahn's drawings in the mail, and while I'm impressed with what's there, I'm somewhat underwhelmed with the hull lines drawings. There is no waterlines (hull bottom view) OR buttocks lines drawings (hull side view) so there's nothing to cross-reference the section slices in 3D space. Soooo... I had to develop a method of inference (filling in the missing data based on evidence) from Oskari's drawings. His side view and bottom view are spectacular, so I drew a transverse plane at each hull frame station (every 24-36 inches), and wherever the buttocks lines passed through each plane, I connected lines to wherever the deck's waterlines (complete with their sheer angles) also passed through each plane, effectively creating a hull frame section for each station.

In doing this, I was also able to accurately determine where Oskari's forward hull frame sections are located. The spacing of his sections are exactly 212.5 inches for the first five sections at the bow, and exactly 425 inches for each section amidship. In doing his spacing like that, none of the sections (except for the forward perpendicular, 18 inches forward of station 156) line up with a physical frame. Why he chose to do that to the forward sections is beyond me, since he did so well keeping them in line with key frames on the rear view sections.

Anyways, attached is an image showing the effectiveness of my inference method on the underside of the bow. Each line is drawn by hand like a connect-the-dots puzzle, so it's taking a fair bit of time. I also can't find any information on the actual shape of the transitional joint between the bow stem and the keel, so I invented my own. It's probably wrong, but without the necessary information, we'll call it close enough for now and leave it alone until I come across hard evidence to make any changes to it.

The bow lines are tricky, and even though I followed the buttocks lines and transverse sections very closely, I came up with a shape that is distorted. This leads me to believe that the drawing that I've been using to guide my work is inaccurate, so I'm going to have to set to work refining the shape to become more fluid. This is going to take some time, as I'll be pushing vertices by hand one by one until they line up in a fluid curve rather than an in-out-in-out irregular sawtooth.

The bow is coming along nicely! I've begun adding buttocks lines at closer spacing to find the areas that still need work, based on whether the lines form a smooth curve or not.

Well, I think I'm 100% happy with the way my basic hull shape has turned out. My next step will be to develop the hull thickness so that the inside walls are not just the back face of the outer hull mesh. I am aware that the wing propeller aft frame is not completed yet, it will eventually replace the section that I have left bright green. Hull details like plating, portholes, doors and bilge keel will get added as time goes on, but the basic shape, to which everything else will conform, is complete.
