Hackaday: How does a design go from the computer screen to something you hold in your hand? Not being able to fully answer this question is a huge risk in manufacturing because . One of the important tools engineers use to ensure success is Geometric Dimensioning and Tolerancing (GD&T).

I thought this article was an interesting look at manufacturing practices that are fairly relevant to theatre. The point of the various controls described in the article is to ensure that all parts created by a manufacturer are created exactly the way they need to be, by providing the acceptable tolerances. Sometimes there is a theatrical equivalent, but as I see it the most direct equivalent is that there is always a person on both ends. The designer creates a design, and measures and scales it the way it should be constructed. They give that design to the shop, where other people absorb that information and use it to cut materials and physically construct the design. Typically the designer does not need to put a tolerance on their designs because it is assumed that the people in the shop understand the designs and will construct them as drawn to the best of their ability. Where measures like the ones in the article become important is when machine production is used. A machine does not read and understand plans, it only does the job it was built to do by someone controlling it. This extra step in the process requires more information to be given to ensure that the manufacturing of a design goes correctly.
