Starting this topic to explore the FreeCAD program and discuss techniques to be used. Being relatively new to the 3D CAD scene, the approaches will be relatively simple and sometimes wrong and can be improved. The project used as an example is a hull model of the New England fishing schooner Adventure and supporting information from http://schooner-adventure.org/about-us/ and details from Howard Chapelle's "The American Fishing Schooner". At some point photographs of the real schooner will resolve details. The objectives of the project are to understand some techniques for getting the 3D hull built, to get as realistic rendering as possible, and explore the opportunities for 3D printing with various options. I have been inspired by some amazing work in other topics in this forum "CAD and 3D Modelling/Drafting Plans with Software". Attached is a current rendering with many unresolved issues. I plan to go back and show how this was assembled and then move forward on the issues. Hoping that this will be of interest and that others will contribute.
I have been working on a 3D CAD model of the USS Oklahoma City CLG-5 as configured in 1971 since 2004. It is just about complete now. I will try to describe the steps I followed to make a very accurate 1:1 scale model, including the problems I encountered and the research (which took most of the time) necessary. I am a former Lieutenant in the US Naval Reserve, and I was the Nuclear/Special Weapons Officer on the Okie Boat from January 1970 through March of 1972, hence my interest in the ship. If you want to know more about the ship, it's history and a lot more, have a look at my web page at https://www.okieboat.com/index.html **** To summarize, the OK City was commissioned in 1944, the 20th of 27 Cleveland class light cruisers. It entered the war in mid 1945 and earned two battle stars, one at Okinawa and one for attacks on the Japanese homeland. After the war it was mothballed, but was chosen in the 1950s to be converted into one of the first guided missile cruisers. It was to carry the Talos surface to air missile. Talos design was changed several times between 1945 and 1955, from a range of 20 nmi, to 60 nmi, and eventually 130 nmi. Meanwhile a Talos test missile was developed into the Terrier missile, and Terrier was the first missile to enter the fleet. The changes to Talos delayed introduction to the fleet until 1958. The Oklahoma City was recommissioned as CLG-5 in 1960. It was a fleet flagship, and served as First and Seventh Fleet flagships for most of it's 19 year service. It was Flagship of the Seventh Fleet for most of the Vietnam War, where it earned 13 more battle stars, becoming the most decorated of all the Cleveland class ships. The OK City was the first ship in the US Navy to use a surface to surface missile in combat successfully, and the first to use an anti-radiation (ARM) missile against an enemy radar successfully. It was decommissioned in 1979 and expended as a target ship in 1999. It was one of the US Navy's historic ships. **** In future posts I will describe the steps I took to research the design of the ship and how I proceeded to make the CAD model. Bear with me though. I am fairly busy with other things and there is a lot to tell. Phil
