This paper presents results of the dimensional calibration of piston-cylinder assemblies to be used for the joint NMI project "Re-determination of the Boltzmann constant". Several measurements optimization strategies are described. For the first time 3D uncertainties in the range of 8 nm (piston) and 16 nm (cylinder) could be achieved.
