A laser crossline device suitable for construction includes at lease a first and a second laser beam produced by diode modules. The diode modules revolve around a horizontal axis so as to form a 360.degree. laser scanning plane that is perpendicular to the horizontal axis of the module. The plane can be adjusted with a bubble level and an adjustment screw. The two modules are situated so as to generate planes that intersect at a right angle. The line of intersection forms a plumb line. If desired, a third orthogonal plane can be added to the device. A single rotary motor drives all of the diode modules.
