AI for ArchiCAD: Automate with Claude
"AI for ArchiCAD" now means something concrete: you can drive your ArchiCAD model with an AI assistant in plain English — read elements, zones, layers, properties and views, and edit BIM data — without writing a line of GDL or Python. This guide explains what that looks like in practice, with real prompts you can run against an open project.
What "AI for ArchiCAD" means today
There are two kinds of AI you might attach to ArchiCAD. One talks about the software — it can explain a workflow or suggest a menu, but you still do the clicking. The other operates it: reads the model, reports on elements and zones, manages layers and properties, and drives views. The second is the one worth having.
HuskyBIM takes that second approach. It connects an AI client — Claude Desktop, Cursor, VS Code or Windsurf — to ArchiCAD through the Model Context Protocol (MCP), an open standard that exposes ArchiCAD's capabilities to the AI as callable tools. You describe a task; Claude picks the tools and the connector runs them on your active project. HuskyBIM for ArchiCAD ships 217 such tools.
What you can genuinely automate
Here are real prompts, grouped by the kind of work they cover.
List every wall on the ground floor with its type, thickness and layer, and flag any thinner than 100 mm.How many doors and windows are in the model, broken down by storey?List all zones with their names, categories and net floor areas, and total the area per zone category.Find every zone with no name or a zero area so I can review them.Read the properties on the element I have selected and show me every custom property and its value.Set the "Fire Rating" property to EI60 on all the walls on the "Core" layer.List all layers and their visibility, then hide every layer whose name starts with "REF-".Show me the available views in the project map, then open the ground floor plan.Give me the project info — name, address, storeys — and a summary of the element counts by type.These fall into a few repeatable patterns: model QA (find things that break a rule), BIM data edits (set properties across many elements), quantity and area reporting (zones, element counts), and project navigation (layers and views). The repetitive, rule-based tasks are exactly the ones AI handles well.
How it works
The chain is short: an AI client (Claude Desktop, Cursor, VS Code or Windsurf) is where you type; the HuskyBIM add-on receives Claude's tool calls; and it drives ArchiCAD over a local connection to read and edit your open project. Everything runs on your Windows machine; the AI client sends your request text and the tool results to Anthropic's models to reason over them, the same as any Claude chat.
Honest limits
- ArchiCAD must be open with a project loaded. The tools operate on the active project; there is no headless mode.
- Windows only, on ArchiCAD 29. Install the add-on that matches your version.
- Review the output. Claude is capable but not infallible. For property edits or anything consequential, check the result and undo if it isn't what you meant. Work on a copy when trying a new prompt.
- Be specific. "Fix the zones" is ambiguous; "set the fire rating to EI60 on every wall on the Core layer" is not. Clear prompts get clean results.

Frequently asked questions
Do I need to know GDL or the ArchiCAD API to use AI for ArchiCAD?
No. You describe what you want in plain language and Claude calls the connector's tools for you. There is no GDL script, no Python add-on and no macro to write. Reading the model output helps you check the result, but you never write code.
Does HuskyBIM for ArchiCAD only read, or can it change the model?
It does both. Across its 217 tools it can query elements, zones, layers, properties and views, and it can also edit BIM data — set element and zone properties, manage layers, and drive views and navigation — on your open ArchiCAD project. Review write operations before you save.
Which ArchiCAD version is supported?
HuskyBIM for ArchiCAD supports ArchiCAD 29 on Windows. It installs as an add-on that connects your ArchiCAD project to an AI client such as Claude Desktop, Cursor, VS Code or Windsurf.
Is my model data safe? Where does it run?
The connector runs on your own Windows machine and talks to ArchiCAD over a local connection. To answer your prompts, the AI client sends your request text and the data the tools return to Anthropic's Claude models, the same as any other Claude conversation. Review AI output before committing important changes.
