Abstract
A building surveying device comprising a base, an upper part supported on the base such that it can rotate about a rotation axis, a sighting unit with a laser source designed for emitting a laser beam, and a laser light detector and an evaluation and control unit. The building surveying device has a plumb point finding functionality which, after being triggered, runs automatically, at least in part, and in the course of which the alignment of the sighting unit is changed under automatic control by the evaluation and control unit with the aid of the first and/or the second rotary drive and as a function of a known, defined first spatial point in such a way that precisely one such second spatial point lying on an object surface is approached and marked by the laser beam, which lies on a vertical plumb line containing the first spatial point.
