As-Built 3D CAD Models
High-Accuracy Scan-to-CAD As-Built 3D CAD Models
We create as-built 3D CAD models of any object, regardless of its complexity or size, using data obtained through 3D laser scanning and/or coordinate measuring machine (CMM) measurements. For 3D laser scanning, we use our terrestrial 3D laser scanners and metrology-grade handheld 3D laser scanners, while our CMM measurements are taken using a laser tracker and measuring arm.
For small- to medium-sized objects, we use CMM measurements from the measuring arm and laser tracker, along with 3D laser scan data from our metrology-grade handheld 3D laser scanner. For larger objects, such as heavy machinery, we typically use terrestrial 3D laser scanners and a laser tracker.
Depending on the project, we frequently combine these methods to achieve the highest accuracy possible while collecting comprehensive data for the most detailed as-built 3D CAD model. For instance, combining terrestrial 3D laser scan data (which typically provides a 3D accuracy of about 2 mm) with data from a laser tracker (which typically offers a 3D accuracy of about 0.02 mm) allows us to achieve exceptional accuracy for critical areas while still benefiting from the broad coverage of 3D laser scanning.
As a result, as-built 3D CAD models created from 3D laser scanning and/or CMM measurements are far more accurate and detailed than those produced using conventional manual methods. Moreover, reverse-engineered as-built 3D CAD models created from 3D laser scan and CMM measurements can be easily converted into 2D CAD drawings.
Our specialized workflows for converting 3D laser scan and CMM measurement data into 3D CAD models allow us to tailor our deliverables to each project’s unique requirements—leaving no room for error.
