Show HN: AI CAD Harness

A new tool called Adam Fusion is pitching itself as an AI sidekick for Autodesk Fusion 360, the popular 3D design app used to make everything from brackets to product prototypes. The setup is almost suspiciously easy — paste one command, restart the app, click a button, sign in, and suddenly a chat panel appears on the side ready to help design parts. But on Hacker News, the real action wasn’t “wow, cool install.” It was a full-on identity crisis for mechanical engineers.

The loudest reaction? “Text-to-CAD is not it.” One engineer basically said writing a super-detailed description of a part sounds more exhausting than just designing it the normal way. Another came in even hotter, begging people to stop using AI on “the most enjoyable part of design PLEASE” — which is the kind of all-caps energy that tells you this debate is getting personal. The split is delicious: some see AI as a boring-task assassin, others see it as barging straight into the one part of the job they actually like.

Then came the startup skepticism. One commenter asked the killer question: if giant AI companies and the design software makers themselves are already building this stuff, why would a thin wrapper win? Ouch. Still, not everyone came to throw tomatoes. A few people said it looked promising, especially for grinding out tedious library parts, and one lonely but relatable plea rose from the crowd: please make this for FreeCAD. In other words, the community verdict is classic tech drama: half “this is the future,” half “this misses the point entirely,” and all of it extremely online.
