Abstract: A method is provided for evaluating and marking deviations of a surface of a part from a design standard for the surface. The method comprises determining a point deviation for each of a plurality of points on the surface and determining deviation regions for the surface. Each deviation region includes only surface points having point deviations within a predefined deviation range associated with the deviation region. The method further comprises preparing a graphical representation of the surface illustrating the deviation regions and applying a copy of the graphical representation to the surface.
