1. A method of recording the location of a point of interest on an object, the method comprising capturing a digital image of an object manufactured according to a design specification and having a point of interest, marking the position of the point of interest on the captured image, accessing a three-dimensional virtual design model of the object, aligning the image with the model, using an algorithm to calculate the location of the point of interest with respect to the model based upon the position of the point of interest marked on the captured image, and recording the calculated point of interest location.
