Project planning, or the capture of current status, for the purpose of documentation, often requires the survey of an object’s geometry, or just some parts of it. In particular, it concerns single points, lines, areas or volumes. An example of this might be a production hall, which is to receive new machines, or be optimized with a new configuration. In order for such rationalization processes to be effective, it is necessary to obtain exact data concerning the position of objects in the hall.
