📄 Paper on arXiv: arXiv:2506.07217

BIMgent is a novel agentic framework that enables architectural building modeling process to be performed autonomously through computer control.

🎥 Demo

Generate a one-storey octagonal building based on the hand-drawn sketch.

🔧 Setup

Software

The current version is based on and developed for the BIM authoring tool Vectorworks. When adapting the repository, please ensure you have Vectorworks installed on your PC. A valid license is required for the software applications.

Prepare API Keys

This project uses APIs from OpenAI and Google (Gemini).
You will need to update the .env file with your own API keys:

env OA_OPENAI_KEY="your_openai_api_key" # OpenAI API key 
Gemini_KEY="your_gemini_api_key" # Google Gemini API key 

Dependencies

Please set up your Python (3.10) environment and install the required dependencies using the following command:

pip install -r requirements.txt

🚀 Get Started

Please update the configuration file at conf/env_config_vectorworks.json before running the agent:

1. Download Required Models

This framework relies on models developed in other repositories.
Please download them and set the corresponding model paths in the configuration file.

🔽 Download Instructions

📦 DeepFloorplan Model

• Repository: DeepFloorplan
• Instructions: Follow the model download guide provided in the repository

📦 OmniParser Model

• Repository: OmniParser
• Instructions: Follow the model download guide provided in the repository

2. Update panel_coordinates to match your tool panel, design panel and object info panel layout.

The format is [x1, y1, x2, y2] where:

• x1, y1 = top-left corner
• x2, y2 = bottom-right corner

Panel Definitions: - Tool Panel: Located on the left side, containing the list of interactable tools. - Design Panel: The central area where users interact to model the building. - Object Info Panel: Positioned on the right side, displaying information about selected components.

The detailed coordinates can be obtained by running the following script:

python mouse_detector.py

Run

Use the following command to run the agent:

python agent_runner.py

To view the logic please check the script:

runner/vectorworks_runner.py
