Ship Ribbing with CAD?
CDR_Ret replied to Sanjith_D's topic in CAD and 3D Modelling/Drafting Plans with Software
I would recommend checking out this thread regarding laser-cut frames, etc. Kiyoo Iizawa was actively involved in this forum a few years ago and did some beautiful work using CG modeling and laser-cut components. He was writing a manual/book to help modelers get into laser-cutting modeling, but after some attempts at collaboration, I think there was an (amicable) divergence of views on how to present the process.

Ship Ribbing with CAD?
CDR_Ret replied to Sanjith_D's topic in CAD and 3D Modelling/Drafting Plans with Software
IMHO, going directly from existing drawings to code that drives a 2D laser cutter is risky when cutting out frames or bulkheads. I have no experience with the quality of plans from the big national museums and other credible sources, but when I manually compared the body and halfbreadth plans of my 1891 brigantine project, it was an exercise in frustration. Heights and breadths of station and waterline intersections did not agree among the three views. The point I am trying to make is that there is no guarantee that using existing plans (especially if they are old, original drafts) will drive a laser cutter that will result in a smooth, fair, hull surface without a lot of extra work. The above observation was the reason I went to CG drafting in the first place. After nearly a decade of periodic frustration, trying different methods and different copies of plans from the Smithsonian and other museum/library archives, I found that using the DELFTship Free naval architecture software was pretty much ideal for fairing out the hull lines because it had the features needed to visualize the shape of the hull, remove low and high spots, and compare the resulting lines to the original drawings. The bottom line here is that obtaining a set of working plans that will actually be fair and eyepleasing in the real world won't necessarily yield the same set of station lines, waterlines, and buttock lines as in the original set of plans you obtained. It is up to you how far you are willing to deviate from the original drawings. There are a number of MSW members who have posted their projects using DELFTship Free, including my own. Comparison of the final modeled stations (green) in DELFTship Free compared to the original G.C. Berger drawing stations. Waterlines (blue) were included to ensure the correct vertical scale. To understand the genesis of these lines, please refer to the Galilee research log in my signature. (High-resolution plans obtained from the San Francisco Maritime National Historical Park Library; G.C. Berger, Pacific Marine Research Society; Date and provenance unknown.) Once you have what appears to be a valid set of lines to work with, then you can start thinking about what laser setup to use for cutting out your parts. Remember to cut to the outside-most of the front and back curves for each frame or bulkhead. Terry -

3D Ropes/Rigging in Blender
CDR_Ret replied to 3DShipWright's topic in CAD and 3D Modelling/Drafting Plans with Software
So far, so good! -
Welcome aboard, Kevin! Yeah, the Lewis and Clark is nothing but HY-80 razor blades. There are quite a few (mostly former) bubbleheads as members here. Terry

Hey, Deyson. Another Coloradoan! Where are you located? I'm retired and living near grandchildren in the Springs. Great to have you aboard! Terry

Viriato. Eu sugiro usar o translate.yandex.com tradutor português / inglês. Isso parece fazer um trabalho muito preciso. (I suggest using the translate.yandex.com Portuguese/English translator. That seems to do a really accurate job.) Terry

Try reading it via the link on a mobile phone. Worked fine for me. Sad outcome.

My laser cut planks
CDR_Ret replied to modeller_masa's topic in Building, Framing, Planking and plating a ships hull and deck
You guys should work up a tutorial for developing laser patterns for things like cabin and roof planking, skylights, and other fine details. You might even start a small business of doing bespoke laser cutting jobs to pay for your hobby! Terry -

3D Brig 'Rose' in Blender 3.3x
CDR_Ret replied to 3DShipWright's topic in CAD and 3D Modelling/Drafting Plans with Software
Is there a simple way to add realistic crew in these renders? The main thing that indicates your image is artificial is the absence of any hands visible on deck, or at least at the wheel. Galilee had only eight assigned crewmembers (plus the five scientific expedition members), and all the photos of the ship at sea always had at least a few humans visible topside. Terry -
Most browsers have a feature to translate text to the user's default language. Looks pretty clear to me. Nice job on Bismark! Terry

Where do you call home? I lived in Vermont several times in my life and consider the state my favorite. Lived in the greater Burlington area. I also drove LCT ferries to work my way through college (UVM). Best job ever! Terry

About the NRG
If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.
The Guild is a non-profit educational organization whose mission is to “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.
The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal. The NRG also publishes plan sets, books and compilations of back issues of the Journal and the former Ships in Scale and Model Ship Builder magazines.
