I was assigned a job of making some inspection drawings from some aircraft parts. The models were done in UG and came with drawings with critical dimensions and GD&T. I was using KEYCREATOR (CADKEY) to create the drawings. These parts were designed by CAD jockeys or engineers. If they had to make a complete drawing they would have realized the problems that manufacturing would face with making and inspecting these parts. The article shows a block with a couple of holes in it. Many parts have hundreds of features that have to be defined and inspected. You either do it by sitting down at a computer and verifying that the part matches the model feature by feature or you create a hard copy drawing that anyone can pull out at any time to check a feature. Now many companies are sending out models with minimum annotation. But they are just passing this required function off to the manufacturing company to do the full inspection drawing. This is something that would be much better done by the original design group. Complete drawings are part of the design function.
