The first step is for you to determine the purpose of the 3D laser scan and the software you'll be using, for example do you want CAD drawings, a 3D BIM model, or a 3D virtual tour?
Below, you can explore the wide range of detailed and accurate deliverables that 3D laser scanning can provide, helping you bring your projects to life with precision and efficiency.
What are the Deliverables After 3D Laser Scanning?
Point Cloud
A point cloud is the collection of millions of data points, captured with a 3D laser scanner, that represent the scanned surface or object, each containing an X, Y, and Z coordinate. The point cloud records a digital 3D representation of the scanned environment, capturing geometry, spatial relationships, and physical features. You can import the point cloud into CAD or BIM software to visualize the area as a pixelated, digital version of your site. Point clouds can be processed and used for measurement, analysis, and visualization.
Deliverable: Raw Point Cloud Data or Registered Point Clouds.
File Formats: .e57, .LAS, .LAZ, .XYZ, .PTS point cloud files and Autodesk Recap files in .RCS and .RCP format.
2D CAD Drawings
A 2D CAD drawing is a flat, digital representation of an object or structure created using CAD software. It displays views from different angles, such as top, front, or side, using geometric shapes, lines, arcs, and text to show size, shape, and layout. Point cloud data is imported into AutoCAD to generate 2D CAD drawings, where technicians can document and annotate them with text, dimensions, leaders, and tables.
Deliverable: Floor plans, site plans, elevations, sections, details, isometric drawings, and reflected ceiling plans.
File Formats: 2D sheets in .RVT, .DWG, .DGN, .DXF or .PDF formats.
3D BIM Model
A 3D BIM model is a digital representation of a building that integrates geometry, spatial relationships, and detailed data about its components. Created using BIM software like Revit, the model provides an accurate, intelligent, and dynamic 3D virtual model for design, construction, and facility management. A 3D BIM model includes information on structural elements, MEP systems, materials, and can also include cost and scheduling data. 3D BIM models provide users with the ability to break down building parts by elements or layers and see how they fit into a single finalized structure. For example, users can isolate walls, columns, windows, doors, etc., and alter the design.
Deliverable: 3D BIM Model
File Formats: 3D models in software such as Revit, AutoCAD, ArchiCAD, MicroStation, SolidWorks, Navisworks in .RVT, .NWD, .IFC, .BCF file formats.
Modeling Options: Standard Detail, High Detail, Very High Detail.
3D Mesh Model
Highly detailed 3D laser scan data can be converted into 3D mesh files, such as .fbx, .stl, .obj, and .ply, for use in CAD or surfacing software. Using x, y, z coordinates, CAD technicians can generate a triangulated mesh from the point cloud, creating a volumetrically accurate, high-density, and high-resolution model. This mesh allows clients to easily view the geometry of objects in CAD without navigating the point cloud. Meshes are ideal for representing intricate details, like monuments or statues, and can be used for creating mixed reality experiences, such as those in stadiums during sporting events.
Deliverable: Polygonal Mesh.
File Formats: .FBX, .STL, .OBJ, and .PLY.
TruView
A TruView is a high-resolution panoramic image that can be overlayed on top of the point cloud, making it easier to understand the spatial relationships within the scanned area. Since TruViews are overlaid on the point cloud data, clients are able to take basic dimensions directly from the Viewer for estimating clearances, and distances, etc. It allows users to easily share, annotate, and view detailed 3D laser scan data for decision-making.
Deliverable: Autodesk TruView portable software allows you to open and view the LGS format of the point cloud, as well as overlay IFC (3D model) files.
File Formats: TruViews can be delivered as a .LGS or .LGSX but a structured .RCP will also have images so an end user with point cloud software can navigate this file format similar to a TruView virtual tour.
3D Virtual Tour
A 3D Virtual Tour consists of a series of 360° panoramic images stitched together to create a complete, interactive view of a location. This tool allows your team to virtually explore the space and add digital notes, providing a detailed and immersive experience. The 3D Virtual Tour can be accessed on desktop computers, laptops, tablets, and mobile devices for easy viewing from anywhere.
Deliverable: 360° panoramic images, plus a customizable .LGSx point cloud data file format.

- KMZ File: A KMZ file is a compressed format for geospatial data that stores georeferenced maps. In subsurface utility mapping, it can be viewed in Google Earth or GIS software, allowing for 3D visualization and precise location data to integrate underground utilities with surface maps.
- SiteMap® Personal Access: Digital utility maps are uploaded in SiteMap® GPRS’ free cloud-based software, providing quick access and secure sharing of detailed, geolocated, and layered underground utility maps. The GPRS Mapping & Modeling Team can generate TruBuilt plan views and 3D BIM or Conceptual Site Models (CSM) for better project or facility management.
Tank & Vessel Inspections
3D laser scan data delivers accurate data and a highly detailed analysis when evaluating the condition and integrity of tanks and vessels. A LiDAR point cloud is processed and compared against a CAD/BIM drawing/model or previous scan data to detect deformations, corrosion, weld inconsistencies, and deviations from design specifications. Advanced software generates color-coded deviation maps, cross-sectional analysis, and precise dimensional measurements, allowing engineers to assess structural integrity and compliance with industry standards such as API 653, ASME, or ASTM. This level of detail helps in predictive maintenance, ensuring early detection of potential failures, minimizing downtime, and optimizing repair planning.
Deliverable: Point clouds, 2D CAD drawings, 3D BIM models.
File Formats: .PPT, .PDF, Excel, .XML.
Deformation and Inspection Reports
Deformation and Inspection Reports from 3D laser scanning provide detailed analysis of structural changes, irregularities, or defects in physical objects or environments. Using the precise data captured by the laser scanner, the report compares the scanned point cloud data against a reference model (such as a CAD or BIM file) to identify deviations in shape, alignment, and size. These reports can detect issues such as settling, warping, misalignment, and corrosion in structures, or inconsistencies in manufacturing parts. The output typically includes color-coded deviation maps, dimensional measurements, and detailed annotations, helping engineers and contractors assess the condition of a structure or component, plan for maintenance, and ensure quality control.
Deliverable: Deformation and Inspection Reports.
File Formats: PDF, .RCS, .RCP, .DXF, .DWG, .STL, .OBJ.
