1. A method for visualizing deviations on an actual surface from a nominal surface comprising the steps of:

  • a. mapping the spatial coordinates of an actual surface,b. comparing said mapped spatial coordinates to the nominal surface to produce a three-dimensional distribution of values for deviations D of the actual surface from the nominal surface,c. generating from said distributions a topographical pattern of deviations having generally the same deviation value D, andd. optically laser projecting that topographical pattern onto the actual surface to visualize said deviations D, where said optical laser projecting is made with reference to at least three fixed reference points on said actual surface.
