AbstractA method is described in which a three-dimensional polygon mesh model of an object is analysed to identify a sub-mesh representing a predefined geometric shape. The polygon mesh model is aligned with three-dimensional scan data of an instance of the object. Based on the alignment, the position of the predefined geometric shape is identified in the three-dimensional scan data. Using the position of the predefined geometric shape, metrology data for the instance of the object is derived from the three-dimensional scan data.
