How was AI used when writing the article? Not implying anything, I haven't started reading it (yet).

Certainly a fair question!

The text was hand written, but reviewed by AI and light edits were made. The CAD models that drive a lot of the animations were either sourced or built based on pictures of historical machines. As called out in the credits, the interactive figures were built by myself and Claude Fable 5 (mostly - a bit of Opus 5.5 in there now).

The article itself was built over about 4 months.

Hey, so a bit of self-promotion for some free software I built that you may be interested in.

https://github.com/yuechen-li-dev/Aetheris/

It's a code-first CAD kernel/toolkit specifically to help LLMs with CAD stuff, it's currently AI usable but not very human usable yet since I'm working on the editor UI. Get your Claude to clone it and give it a try and see if it's easier than your current workflow.

I built two 3D mechanical demos with it a couple of weeks ago that you can check out as well. https://aetheris-difference-engine-showcase.yuechenli.worker... https://aetheris-editable-v8.yuechenli.workers.dev/

What CAD do you use for the models, and does it have a CAM simulator (for example, you might actually be able to simulate the tread cutting in Fusion 360 CAM's simulator.

		I used onshape, but just the basics :). The thread cutting was done just as an animation.
