Abstract
A line generating device generates two fan-shaped beams of light at an angle to each other, and projects the beams onto an adjacent surface, where the beams are visible as lines on the surface. A user has access to the intersection of the lines, so that the intersection can be marked or otherwise used in combination with the lines, such as in aligning objects.
