As-Built 3D CAD Models
High-Accuracy Scan-to-CAD As-Built 3D CAD Models
We create as-built 3D CAD models of objects, equipment, and structures of any size or complexity using data obtained through 3D laser scanning and coordinate measuring machine (CMM) probing. For 3D laser scanning, we use our terrestrial 3D laser scanners, metrology-grade handheld 3D laser scanners, and measuring arm 3D laser scanners to capture detailed surface geometry across a wide range of applications. For CMM probing, we use our laser tracker CMMs and measuring arm CMMs to collect high-accuracy dimensional data of critical features and geometries. By selecting the most suitable combination of 3D laser scanning and CMM probing methods, we are able to create precise as-built 3D CAD models tailored to each project’s specific requirements.
For small- to medium-sized objects, we often combine CMM probing from our measuring arm CMMs and laser tracker CMMs with 3D laser scan data from our metrology-grade handheld 3D laser scanners and measuring arm 3D laser scanners. This approach is especially effective for parts and equipment that require both fine detail and high dimensional accuracy. For larger objects, such as heavy machinery, industrial equipment, and large assemblies, we typically use terrestrial 3D laser scanners together with laser tracker CMMs to capture broad geometry efficiently while maintaining high accuracy in critical areas.
Depending on the project, we frequently combine terrestrial 3D laser scanning, metrology-grade handheld 3D laser scanning, measuring arm 3D laser scanning, laser tracker CMM probing, and measuring arm CMM probing within a single unified workflow to produce the most accurate and detailed as-built 3D CAD model possible. Each method contributes different strengths: terrestrial 3D laser scanning efficiently captures large-scale geometry and overall spatial relationships, metrology-grade handheld 3D laser scanning and measuring arm 3D laser scanning capture smaller features and complex surfaces in greater detail, and laser tracker CMM and measuring arm CMM probing provide high-accuracy dimensional data for critical geometries and key reference features. By seamlessly integrating these datasets, we can refine broader 3D laser scan coverage with higher-accuracy CMM measurements and supplement large-scale 3D laser scan data with finer-detail 3D laser scan data where needed. This combined approach increases both overall accuracy and level of detail, ensuring that the final as-built 3D CAD model accurately reflects existing conditions across the entire object, from major geometry down to critical features.
As-built 3D CAD models created from 3D laser scanning and CMM probing are significantly more accurate, detailed, and reliable than models produced using conventional manual methods. They can be used for inspection, reverse engineering, equipment modification, redesign, fabrication support, and technical documentation, and can also be further developed into as-built 2D CAD drawings and documentation when required. Using specialized software and refined workflows, we convert raw 3D laser scan data and CMM measurement data into deliverables tailored to each project’s geometry, required level of detail, and intended application.
