Build a working 3D machine simulation from one line
AirsupHQ's Machine Skill has Claude Code turn one line of text into an interactive 3D machine simulation; the author reports a 3,597-part jet engine producing about 340 kN of thrust.
Done with Claude Code
What they did
AirsupHQ released Machine Skill, an add-on for Claude Code. You type /machine plus a one-line description, such as a turbofan jet engine or a refinery pump. Claude looks up the real machine's size and physics. It writes a small calculator for how the machine behaves. Then it builds an interactive 3D web page in a single file. The page can pull the machine apart, cut it open, see through it, or break it. A script then records a video of it.
How it went
The author reports examples, each made from one line. A turbofan jet engine with 3,597 parts produces about 340 kN of thrust, based on the standard jet engine cycle. A rocket engine reaches 2,462 kN. A pump and a compressor are cut open for plant training.
Worth knowing
The project page says to name the real thing, like "a turbofan like the ones on a 787". It also says to state what should move and what should break. Recording the video needs Node and the free FFmpeg tool.
Try it yourself with Claude Code
/machine [a specific real machine, e.g. a centrifugal pump of a named type], cut open for [audience or purpose]. Look up its real dimensions and operating point. Write down the physics that drive it before you build. Show [what should move] and let me break it by [failure to simulate]. Output one standalone HTML file with cutaway, explode and labels. Show the equations under 'How it is computed'. Then tell me the record command to make a [1080x1080 or 1080x1350] film of it.
Swap the highlighted [parts] for your own details.
