A system includes a pose manipulation system operationally that sets a pose of a position measurement system with respect to an object that is to be measured. The system further includes a pose tracking system configured to record a relative pose between a coordinate system associated with the position measurement system and a coordinate system of the object. The pose tracking system records a path along which the position measurement system is enabled to measure 3D coordinates of a surface of a type of an object, wherein recording the path comprises moving the pose manipulation system sequentially through a plurality of poses and recording, at each pose, the relative pose to measure the 3D coordinates. The pose manipulation system follows the path again, and the position measurement system measures the 3D coordinates by applying one or more of the recorded poses.
