description 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 generator operable 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 a second plane of light having a fan angle greater than 180° and arranged in the housing to project 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 the second plane of light at two points. A third laser light generator is operable to emit a third plane of light having a fan angle greater than 90° from the housing and arranged in the housing to project the third plane of light perpendicular to the first and the second plane of light, such that the third plane of light intersects with both the first and second planes of light.
