The sequence illustrates dimensional verification between a C A D model and a scanned gear component. The first model is labelled C A D File, followed by a 3 dimensional scanned file. The next stage shows Alignment between the two models. The final model displays a Coloured Deviation Map indicating dimensional differences between the scanned and original geometries. A vertical scale on the right ranges from minus 1 point 00 millimetres to 1 point 00 millimetres with intermediate values near minus 0 point 05 and 0 point 05 millimetres.Illustration of the reverse engineering validation workflow: starting with the CAD model, progressing through 3D scanning, alignment and generating a deviation map to quantify dimensional deviations
