Laser scanning data is represented digitally in the form of point clouds. These files display millions of little dots (“points”) arranged in the shape of the object or space that you have scanned. Usually, LiDAR scanners take the measurements used in the creation of point clouds, and specialized software is used to compile and later edit them. Once you have a point cloud, the opportunities for using it in your work are virtually endless. For starters, you can alter the file to create even better representations of the space by:
Many construction professionals use point clouds as a sort of reference model to build a 3D sketch around. You can pull the cloud apart and isolate certain sections to facilitate creating the BIM sketch, and you can also use point snapping to build directly over the point cloud.
Architects, engineers, surveyors, and general contractors are some of the professionals that outsource scan to BIM modeling services to competent providers. MEP designers and contractors also utilize scan data conversion services for architectural and structural building objects.
It’s not always been easy to develop 3D BIM models from point cloud data. Many times, it required the use of several applications and workflows. Today, the scan to BIM capability is available as a BIM software. It enables designers to visualize, manipulate, and verify point clouds within a single environment.
By visualizing objects in 3D and creating geometry inside software like Revit, architects and engineers can improve transparency, precision, and efficiencies in production time.
How Scan to BIM Works?
The process starts with reality capture using laser scanning equipment and software. The captured digital imagery constitutes point clouds, which are sets of vertices within a 3D coordinate setup. Coordinates X, Y, and Z usually define point clouds to represent the exterior surface of an object. Then, designers use scan to BIM to process the captured point cloud data into BIM models.
How Good are the BIM Models Processed From Point Cloud Scans?
Converting point cloud scans to BIM makes it possible to create accurate 3D drawings based on as-built conditions. Contractors can use the precise information in retrofit or adaptive reuse construction projects. They may also combine the three-dimensional insights with BIM drawings for new areas of a building undergoing modification.
The final BIM models portray all building elements accurately, for example, beams, columns, MEPF fittings, and even some aspects of the exterior living spaces. They feature the geometry, location, and dimensions of windows, millwork, plumbing lines, internal walls, and other building elements.
Scan to BIM conversions deliver much more than 3D building insights. They provide multidimensional BIM models with critical, actionable intelligence embedded within them. Along with the X, Y, and Z coordinates that convey precise geometrical information, construction time, cost, and materials help provide a complete picture of the building elements in question.
What are the Perks for You?
Three-dimensional BIM insights developed from laser scan data offer contractors the following advantages:
If you’re extracting your building information by laser scanning, you’ll need to convert the insights to BIM models for streamlined 3D workflows. INDBIM scan to BIM services can help with that aspect of your AEC project design!
