Topcon Positioning Systems released Version 6.11 of its 3D Office and Pocket 3D software. The new 3D machine control software has a new real-time, color-coded cut/fill mapping feature displaying where material is located on the jobsite and where it needs to be moved. By simply comparing the existing surface to the finish design, the operator can see on the control box cut, fill and on-grade areas in different colors. As the operator moves across the site, the screen automatically changes color to represent the cut or fill required to achieve grade. With this feature, every operator can move the material to the right spot the first time. When completed, the surface fill can be saved as an as-built for finish grade confirmation. The cut/fill feature can also be used for compaction verification in waste landfills or building pads. Users can define screen color changes by the number of passes over an area or by a special “previous pass height differential,” which changes screen color based upon a predetermined change in elevation. This new option ensures optimum compaction in the fewest passes possible, saving time and equipment cost. With the new version, users can set up their machines and survey rovers to work within a network without the need for a base station. The “instant on” availability saves time on small and large projects resulting in increased productivity and profits. Topcon’s mmGPS can also work within a network, guaranteeing that even the tightest tolerance specs can be met. (Topcon, Livermore, Calif.)
