Use an agent to draft parametric geometry systems

A Rhino plugin let a coding agent turn a brief into editable geometry logic stored alongside the project files.

What they did
Miro Bannwart connected his Rhino/Grasshopper plugin to an external coding agent and limited it to a saved project folder. The agent started by asking about the design goal, then created linked Geometry Stations and wrote their code and inputs into text files. Miro reviewed the canvas and adjusted the parameters; in one test, they annotated a screenshot with red and green marks to fix a staircase handrail.
How it went
The setup produced examples including a chest of drawers, a curved staircase, a villa, a bookshelf, and a timber frame. It is still in an experimental alpha stage. Miro got the best results from GPT-6 Astra, and local-model runs failed.
Tips
Keep the agent boxed into the project folder, and save backups before testing. Begin with a small model, and be careful with IFC export because reimport can fail and the export can take minutes.

Try it yourself with Claude Code

I want to make a parametric model for [object or structure] using [Grasshopper / CadQuery / another modeling library]. Start by asking the smallest set of questions you need about the form and the controls I want. Then build the system in [project folder path], and store the code plus each input value as text files next to the project. Show me the result and wait for my approval before you send, export, delete, or submit anything. After that, test three different input combinations, save each one, and stop when all three run without errors. End with a brief guide that tells me which values to edit for [width], [height], [density], and any other controls.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
