摘要：An improved laser line generating device is provided for use in construction
layout tasks. The laser line generating device is comprised of a first laser light generatoroperable to emit from a housing a first plane of light having a fan angle greater than 180°and arranged in the housing to project the first plane of light perpendicular to a
horizontal plane; and a second laser light generator operable to emit from the housing asecond plane of light having a fan angle greater than 180° and arranged in the housing toproject the second plane of light perpendicular to the first plane of light and
perpendicular to the horizontal plane, such that the first plane of light intersects with thesecond plane of light at two points.
