I gave GPT-6 Astra one prompt. 9 minutes later it built a complete parametric drill assembly in Fusion 360.
Full feature tree. Zero clashes. Then I asked for design changes and it ran them without a single broken reference or rebuild error. In this video I walk you through the exact workflow, the tools you need, and the honest verdict on where this actually works and where it will burn you.
What’s in this video:
📌 How to connect ChatGPT Codex to the Fusion 360 MCP server (step by step)
📌 Testing the connection with a simple M6 nut
📌 Generating a detailed assembly prompt with ChatGPT and running it in Codex
📌 The full drill assembly result, and the design fixes (ergonomic handle, sharp drill bit, battery strap)
📌 The two big problems: natural language isn’t how engineers specify geometry, and the token cost is brutal
📌 The details that looked right at a glance but fell apart on inspection
📌 Where I’d actually use this today (visualization, smaller components) and where I wouldn’t let it near my files
📌 Why I think this becomes a game changer within a year
