Leica Geosystems released Version 4.5 of the GradeStar 3D automatic machine control system. GradeStar's exclusive automatic side-shift functionality has been enhanced in Version 4.5. The operator can now pick any polyline from the plan view window and select it as a horizontal reference or center line. GradeStar will automatically utilize the selected line and calculate real-time offsets to it. These offsets can be displayed on the screen, or in the case of a motorgrader, used to operate the hydraulic side-shift function. Other improvements include new data screens and views, and the ability to store hydraulic tuning settings and vehicle data in the vehicle settings files, making it easier to swap the system from machine to machine.
