I've been building software where an AI coding agent writes Ruby code that generates a verified 3D model of a stone and timber building. Every detail, defined in code, implemented by AI, verified computationally before I start building
I over the last few months I've asked Claude to search the internet for anyone doing something similar. It never found anything
The project: I describe what I want to build. Claude researches the technique, creates reference documentation, implements the geometry, and a verification pipeline checks everything is in the right place
The AI doesn't just generate geometry, it proves the geometry is correct, then fixes what doesn't pass
I asked Claude to search for similar projects more than a dozen times across different conversations. Always said it couldn't find anything
So I tried something different. Instead of asking Claude to search, I asked it to deeply understand my project and write me a search prompt I could give to Grok
Claude read through 25,000 lines of modeler code, over a hundred craft knowledge docs, the full build pipeline, the verification system, and distilled it into a prompt describing exactly what to look for and what to exclude. No AI image generators, no generic copilots, no chatbot Q&A. Only projects where AI writes executable code that produces verified geometry
I gave that prompt to Grok
Grok found a whole ecosystem:
@mfranz_on using Claude Code build123d for parametric CAD with manufacturing-ready STEP output
@ruben_kostard building ForgeCAD, open-source AI-native code-first CAD
@data_shapes building "Claude Code for Revit" (OkPy Agent)
@BIMOpsStudio connecting Claude agents to live Revit BIM models for geometry and compliance checks — FreeCAD AI workbench turning natural language into executable Python for 3D models
@tom_doerr's vcad, an AI agent system for parametric CAD
@OtivDev's grandpacad using LLMs to generate OpenSCAD models
@yongyuanxi doing end-to-end AI code generation in Rhino/Grasshopper
The space is growing fast. CadQuery, build123d, OpenSCAD, FreeCAD on the code-first side. Revit and Grasshopper on the architecture and BIM side
I'd been building in what I thought was an empty field, but lot's of people had the same insight. AI is great with code, so if you define your design in code, AI can build it
The thing that found them wasn't a web search. It was asking one AI to understand my project deeply enough to describe it in terms another AI could search for
Claude couldn't find these projects on the open web
But Claude understood what made mine distinctive
And Grok leveraged its X data access to find recent posts about similar projects
