  • Ensuring tunnel designs stay within specified design parameters and tolerances
    Patent number: 10248299
    Abstract: The present invention is directed to a computer system and methods for designing a tunnel in accordance with tunnel design parameters. The computer system and methods load a tunnel design as a visual model of a respective tunnel on a user interface. The computer system and methods enable a user to select a point on the user interface, such that the point defines one or more objects of the visual model. The computer system and methods further enable the user, using a pointing device, to move the point toward a desired location on the user interface, such that the pointing device traverses a plurality of locations on the user interface. As the pointing device traverses each of the plurality of locations, the computer system and methods provide a real-time preview of the respective placement of the selected point and the one or more defined objects on the user interface.
