edented efficiency to applications such as creating CAD templates; 3D visualization and navigation; capturing as-built measurements; build - ing information modeling (BIM); and highly accurate measurements for custom fabrications. The Leica 3D Disto uses your own Windows device to operate, with intelligent software making it possible. This software controls the tool, automatically carrying out all complicated calculations in the back - ground while only supplying the relevant information needed. Users can see directly what has been measured, either as a live image sup- plied by the integrated camera, or as a three-dimensional model. The 3D Disto measured to within 1/16” (1.58 mm) accuracy by project - ing the image it saw on the accompanying wireless touchscreen tablet. The robotic feature of the 3D Disto allowed it to shoot all required points from the opposing concrete rebate arches within an hour. The measurements were then loaded in a file within 15 minutes and directly emailed from the jobsite to the product engineer in Colorado. Here, the engineer was able to overlay the 3D measurements into his CAD program. The process was both fast and highly accurate and gave confidence to Reynolds Polymer that the window would fit exactly as needed. The custom acrylic window was lifted through a special framed open- ing in the roof of the Georgia Aquarium and place onto the concrete rebates, where it fit with precision and within tolerance. With this process, Georgia Aquarium, Brasfield & Gorrie, and Reyn - olds Polymer have provided an exceptional viewing window to the shark exhibit without concern for project delays or cost overruns.
Prefabricated or assembled building products, whether they be the acrylic window at Georgia Aquarium or granite countertops for resi - dential kitchens, create challenges to ensure that the components fit into the site-built frames and irregular spaces of partially build structures. Highly accurate site measurements, especially for these expensive custom fabrications, ensure these puzzle pieces fit together well and without costly rework or damage. Regardless of large or small toler - ances, the assurance of the 3D Disto accuracy eliminates guesswork and costly errors and reduces time used to compensate for inaccuracies.
