摘要
A light table includes a housing extending in a horizontal direction having legs extending downwardly therefrom. The housing defines X- and Y- axes and has an X-Y grid pattern formed thereon and visible from above the housing. A lighting system is used to illuminate the grid pattern. A frame extends vertically upwards from the housing and defines a Z-axis having an X-Z grid pattern formed thereon. A second lighting system illuminates the grid pattern on the vertical frame.
