AutoGAD: Claude inside AutoCAD
An LLM agent docked inside AutoCAD 2025 that reads, audits and edits live drawings.
AutoGAD is a .NET 8 plugin for AutoCAD 2025 that adds a ribbon tab and a dockable WhatsApp-style chat palette backed by Claude (or any OpenAI-compatible model).

The agent receives a compact drawing snapshot (layers, layouts, block inventory, schedule text) and calls tools that query entities, tables and layers from the live database, or modify the drawing through confirmed write tools such as global text replacement, layer state changes and custom properties.
It keeps per-user and per-drawing notes between sessions and reports the token cost of every answer.
Built for real electrical/lighting design documentation work.
What it does
- Ribbon tab + dockable palette with Markdown-rendered chat, effort selector and auto-approve toggle
- Read tools: query_entities, get_block_inventory, get_layers, get_tables, get_context over the live DWG database
- Write tools with confirmation dialogs: replace_text (text, attributes, MLeaders, table cells), set_text, create_text, set_layer_state, set_custom_property, run_command
- Persistent memory keyed by drawing fingerprint GUID; per-turn and per-session cost reporting
- Two installers: per-user Inno Setup EXE with registry demand-load, and per-machine WiX MSI shipping an Autodesk Autoloader bundle
- Engineering-domain persona for Russian working documentation (loads, breaker sizing, cable checks)
Production-grade AutoCAD plugin used daily by the author as a design engineer; complete LLM tool-use loop with prompt caching, adaptive thinking and dual provider translation (tool_use <-> tool_calls); two installer technologies; version 1.0.5.

I build it live on a Zoom call, you watch the screen, the timer stops when you say stop. First 15 minutes are free.
