Abstract: An interactive graphics system for modelling physical articles, includes a measurement device connected bi-directionally with a central unit to which a video screen and a keyboard are connected, as well as processing media which are suitable for receiving from the measurement device, at least, data on initial model identification points, and for controlling the automatic collection of addition data regarding the model by means of the same measurement equipment in order to provide such data for processing for use in deriving the model.

Abstract: An error compensated, coordinate measuring machine includes a ram, a supporting structure for the ram and a base on which an object or part to be inspected is secured. The ram is mounted to the structure and movable with respect thereto. An object sensing probe is mounted to the ram. The probe is responsive to contact with the part or object being tested. Sensors are mounted to the ram and the base. The sensor on the ram detects the angular deviation of the ram from a reference plane, and the sensor on the base detects the angular deviation of the base from the same reference plane. A calculator unit determines the difference between the angular deviations of the ram and the base from the reference plane. The machine further includes transducers which measure the position of the ram with respect to the supporting structure, and the position of the supporting structure with respect to the base. The transducers provide ram positional data.
