<p>The device (10) has a horizontal line projection functionality for measuring and marking space points (1a 1b, 1c) along a horizontal line on a shaped surface. An evaluation and control unit automatically controls Azimuthal alignment of a sighting unit based on the first space points defining a horizontal plane (16) with respect to the functionality such that an elevative alignment of the sighting unit is changed by rotary drives. The second space point is moved and marked with a laser beam (14), and lies in an actual Azimuthal alignment to the horizontal line. Independent claims are also included for the following: (1) a method for measuring and marking space points in a common horizontal plane of a construction by a construction measuring device (2) a computer program product comprising a program code for executing a method for measuring and marking space points in a common horizontal plane.</p> |
