A system for marking a corner angle in a working area with the aid of light planes, wherein a straight, elongate guide is disposed on each respective side of a planar working surface in the working area. Each guide carries a carriage that can be moved to chosen positions alongs its guide. Each carriage carries a laser unit which is adapted to emit a light plane that intersects the working surface, as well as the light plane of the other laser unit, at a chosen angle. Each laser unit is adapted to maintain its light plane in a set orientation relative to the longitudinal axis of its associated guide, regardless of the position to which the carriage has been moved along said guide, and both laser units are adapted to be activated simultaneously for marking said corner angle. |
