A fixture assembly for holding a part to be measured in a specified and elevated orientation and being utilized in combination with an existing coordinate measurement machine. A transportable body is provided having a horizontally arrayed and upwardly facing platform. The coordinate measurement machine is adapted to be arranged in proximity to the transportable body. First, second and third datum blocks are secured upon the upwardly facing platform at first, second and third selected locations. Each of the datum blocks further includes an upwardly facing tapped hole for receiving a measurement target which is capable of being manipulated according to instructions provided by the coordinate measurement machine to define first, second and third datum planes according to a coordinate system defined for the part to be measured. A plurality of individual support units are secured upon the platform at locations specified by the coordinate measurement machine. The individual support units each further include an upwardly facing receptacle bushing within which is defined a tapped hole for receiving one of any suitable type of measurement target and is capable of being manipulated according to instructions provided by the coordinate measurement machine to define an associated plurality of individual part supporting points. Each of the measurement targets within the receptacle bushing is replaced by a part support pin upon the coordinate measurement machine defining a correct location for the supporting point.
