Your AI sees shapes. dirhp gives it the building.
Why an assistant in Rhino needs more than geometry, and what dirhp adds: meaning, data and history that stay with the model as it changes.
The model holds shapes
A Rhino model holds surfaces, curves and solids. It does not hold what those objects are. That knowledge sits in layer names, in attributes and in the designer's head.
Ask an AI assistant to change "the shopfront glazing" and it has to go looking. It reads the layers, pulls the objects, gets their metadata, sorts through them and guesses. Then it does it again on the next request. On real models, that is not reliable.
To your AI, every object is a shape.
What dirhp adds
dirhp organizes your Rhino design so the assistant you already use knows what the objects are, not only their shapes. It adds three things:
- Meaning. You describe objects in the words your practice uses, such as shopfront, party wall or canopy. One object can hold more than one meaning. There is no fixed schema.
- Data. The assistant fills in attributes for a whole set of objects at once, for example thickness, type, supplier and product on every glass panel.
- History. Saved states let you go back to an earlier design option.
Because the meaning is recorded, the answer to "where is the shopfront glazing?" already exists. The assistant does not work it out from scratch each time.
It fits around your tools
Your .3dm file stays where it is and is not uploaded. Your layers and object names stay as they are. Changes made through the assistant are ordinary Rhino edits: they show in the viewport and undo like anything else.
Your AI assistant stays yours. It runs on your own account with your own provider. dirhp works with Claude Desktop, Claude Code and the ChatGPT desktop app today.
What comes next
dirhp is in free early access. We are working with a small group of designers who model in Rhino and use AI assistants every day. Some questions are still open, such as how dirhp should work with Grasshopper. We would rather answer them with you than guess.
