Drawings and Fabricaiton documentation

Drawings and technical documentation is the key of manufacture. It allows clearly define requirements such as tolerances and deviations, datum points, flatness, roughness of surfaces, circularity, cylindricity, material, post manufacturing process, etc. It also allows to define assembly process and indicate all required parts in bill of materials. It's always important to think about technological processes in order to make sure that all designs will be in range of manufacturing possibilities.
