ABSTRACT:
A reference beam generator has first, second, and third projection turrets for projecting first, second, and third fan beams of laser light, respectively. The first, second, and third fan beams of laser light are oriented normal to each other. The turrets may be rotated such that each of said fan beams can each be rotated about an axis that is normal to the plane in which the fan beam is projected. The generator may be used to project a number of reference points and lines on multiple surfaces.
