BuildLens is an AI-powered engineering workspace designed to bridge the gap between building drawings and 3D visualization. It helps civil and structural engineers interpret architectural and structural documents, extract important building information, identify inconsistencies and reconstruct building components in an interactive 3D environment. Users can upload project documents and communicate with an AI engineering assistant that helps interpret the supplied information, organize structural elements and identify missing or conflicting details. The application uses Three.js to visualize building geometry, including structural frames, walls, slabs, foundations, roofs and reinforcement where supported by the available information. Users can inspect the resulting model, explore different structural views and navigate through the building. BuildLens aims to make engineering information easier to understand, coordinate and explore while keeping engineering assumptions and unverified information clearly identified.
