Adam Fusion Claims 'v0 of CAD.' Skeptics Aren't Buying It.

Adam Fusion plugs into Autodesk Fusion 360 and tries to turn text prompts into CAD operations. One terminal command installs it on macOS or Windows in about 10 seconds. There's a free tier, no credit card needed.

The startup describes this as agents driving CAD natively, but doesn't explain much about how the agents actually work. The extension appears in Fusion's AddIns panel after installation and converts text instructions into CAD operations within the software. Beyond that, the technical details are thin.

Guillermo Rauch, CEO of Vercel, called Adam "v0 of CAD." Eli Brown from Y Combinator praised it for cutting through "decades of cruft" in traditional CAD software. YC partners Dalton Caldwell and Brad Flora also endorsed it.

Hacker News commenters aren't sold. One user questioned whether Fusion's internal data model is structured enough for text-based LLMs to really understand. They suggested a "CAD-as-code" approach might work better, given how LLMs handle structured formats.

Someone with mechanical engineering experience pointed out that writing accurate prompts often takes longer than just using traditional CAD tools with a space mouse.

The skepticism is fair. CAD is precise work, and the gap between "make this part fit" and actually making it fit involves domain knowledge that's hard to compress into a prompt. But if Adam can make common operations faster, that's worth something. The free tier makes it easy to find out whether the reality matches the pitch.
