Dimensional Measurements
Examples at traceable standards 

Example: Outer size measurement at a block:Sample: Precise metal block previously measured with metrology instruments in a calibration laboratory:
Result:
By measuring a set of such parameters it is possible to determine e.g. the central axis of a cylinder, the center of a hole or the zeropoint of the 3dimensional coordinate system from a sample.
Many other examples of dimensional measurements are described in the area of 2D and 3D Profile Measurements, see for example:
