Abstract
A construction surveying device having a base, an upper part mounted on the base and can be rotated about an axis of rotation, a sighting unit having a laser source which is designed to emit a laser beam and a laser light detector, and an evaluation and control unit, a first rotary drive and a second rotary drive enable the upper part and the sighting unit to be driven and aligned, a spatial alignment of the sighting unit with respect to the base can be detected using two goniometers, and coordinates for space points can be determined using the evaluation and control unit, the construction surveying device has a horizontal line projection functionality which, at least sometimes, takes place automatically after triggering and is intended to measure and mark space points along a horizontal line, running in a horizontal plane, on an arbitrarily shaped surface.
