1. A computer-implemented method for determining a course of motion between an artefact and a measurement device for interacting with the artefact, the artefact and the measurement device being moveable relative to each other in at least one linear and one rotational degree of freedom, the method comprising: receiving, by a processing unit and before the measurement device and the artefact relatively move in a position sensing relationship so as to obtain measurement data about the artefact, first geometric data representing the artefact; receiving, by the processing unit, second geometric data representing the measurement device; and automatically determining, by the processing unit, the course of motion between the artefact and the measurement device based upon the received first and second geometric data, the determining of the course of motion including: determining, from the received first and second geometric data, instructions for automatically manipulating a relative angular orientation between the measurement device and the artefact about the at least one rotational degree of freedom as the measurement device and the artefact relatively move in the position sensing relationship so as to obtain the measurement data about the artefact along a measurement path, wherein the instructions for automatically manipulating the relative angular orientation comply with one or more optimisation criteria.
