Converting dense amounts of 3D spatial data into structured BIM models is known as point cloud to BIM conversion. The BIM model provides intelligence geometry combined with metadata while the point cloud serves as a digital representation of reality. Point Cloud to BIM or Point Cloud Scan to BIM is the process of turning the information gathered from Point Cloud scans into an intricate digital model of the structure. In order to construct 3D BIM models point cloud data must be imported into BIM software and used as a guide. It offers details on the geometry, constructions, material layout MEP equipmentand other aspects of a building.
