ASME Y14.41

ASME Y14.41 is a set of guidelines that tells people how to make really good technical drawings of machines and parts. Imagine you want to make a drawing of a toy truck or an airplane, these guidelines tell you things like what kind of lines to use, how big to make the parts, what symbols to use to show things like screws or bolts, and how to organize the drawing so it's easy to understand. This is kind of like following a recipe that tells you what ingredients to use and how to mix them to make a yummy cake. Following these guidelines ensures that the drawing is clear, accurate, and easy to read so other people can make the same toy truck or airplane and it will work properly.
