Abstract:
1. A method for setting up a layout and point transfer system, said method comprising: (a) providing a first base unit which includes a first laser light transmitter that emits a first laser light plane; (b) providing a second base unit which includes a second laser light transmitter that emits a second laser light plane; (c) positioning said first base unit and said second base unit at two different locations on a solid surface of a jobsite; (d) providing a remote unit for use on said jobsite; (e) determining an alignment axis between said first base unit and said second base unit; (f) aiming said first laser light transmitter at a first static direction and said second laser light transmitter at a second static direction so that a first benchmark point is indicated by intersecting laser light lines along said solid surface, which are produced by said first and second laser light planes; and determining a first set of azimuth angles of said first and second laser light transmitters; (g) aiming said first laser light transmitter and said second laser light transmitter so that a second benchmark point is indicated by intersecting laser light lines along said solid surface, which are produced by said first and second laser light planes; and determining a second set of azimuth angles of said first and second laser light transmitters; (h) by use of said first and second sets of azimuth angles, determining positions of said first and second base units with respect to said first and second benchmark points; and (i) by use of said remote unit, storing: (A) said first set of azimuth angles of said first and second laser light transmitters, (B) said second set of azimuth angles of said first and second laser light transmitters, and (C) said determined positions of said first and second base units with respect to said first and second benchmark points.
