Scan to BIM (Building Information Modeling) is a digital transformation process that converts laser-scanned point cloud data into an intelligent 3D BIM model. This process plays a crucial role in architecture, engineering, and construction (AEC) by providing accurate as-built documentation for renovations, facility management, and infrastructure development.
