Measuring modeling validating testing where we stand

When I first started in a development department, measuring parts was done with simple tools like calipers, micrometers, dynamometers… new equipment started to appear resorting to 3D measurements automatic measurements with a computer with a ball pointer. Drawings were not measurement friendly making it difficult to measure according to new technologies. Today’s approach take seriously GDT and combining it with CT scans (3D scanner) a new approach is starting to grow resorting to model based definitions. Since all the information necessary for measurement is in a model when a CT scan is performed one can imideatly discover part variation and perform analysis on the intended planes with no miss communication.
