Auto3DBuilder: An automatic 3D building modeling tool from 2D drawings

Abstract: This paper presents a novel 2D to 3D building modeling tool seamlessly integrated into our Smart City Lab platform. The tool, designed for simplicity and user-friendliness, enriches existing LoD1 buildings without requiring modeling expertise. Leveraging Grasshopper as a backend and utilizing RestAPI interfaces, it transforms 2D architectural drawings into detailed 3D models. We delve into the methodology, showcasing how users can effortlessly generate intricate building models. The potential applications extend to urban planning, simulations, and innovative technologies like AR, VR, and the metaverse. Acknowledging current limitations, we outline prospects for future advancements, including accommodating more sophisticated building designs and enhancing interoperability for extensive data integration. This tool marks a significant step towards extensive and interactive urban development and planning.
