The architecture, engineering, and construction (AEC) industry is significantly advancing with the inclusion of Artificial Intelligence (AI) in engineering practices, especially in design. Traditional methods often fall short in real-time collaboration and adaptability, causing inefficiencies. To address these issues, this paper presents a novel system combining Building Information Modeling (BIM), Virtual Reality (VR), and AI. The proposed system is crafted using Python and the Generative Pre-trained Transformer (GPT) model, connected to Autodesk Revit via a custom. NET dynamic link library (DLL). Central to this innovation is an AI-powered chatbot, which can process vocal commands to instantly modify BIM models, including changing element visibility, deleting elements, and altering types. This allows for rapid adaptation to design changes and enhances real-time collaboration. Integrating this with VR through real-time 3D visualization software provides an immersive experience, letting users view and interact with model modifications immediately. A use case presented in the paper demonstrates the system’s ability to streamline feedback and decision-making processes, overcoming traditional design constraints. The AI chatbot interface makes advanced BIM functionalities more accessible to a wider range of professionals, simplifying the learning process. This BIM-VR-AI integration marks a significant step forward for the AEC industry, promoting increased efficiency and collaboration. It exemplifies the potential of AI to enable dynamic, real-time interactions within BIM and VR, revolutionizing the design phase of construction projects.
