ISO 128

ISO 128 is a set of rules that people use when making drawings or illustrations of objects, buildings, or anything that we want to show with pictures.

This set of rules tells us how to draw things so that everyone can understand them easily. We use different symbols and lines of different thicknesses to convey different information such as what the object is made of, how big it is, its shape and dimensions.

For instance, if we want to show a wall, we use a thick and solid line to outline it. This signifies that the wall is something we can’t see through. If we want to show a door, we may use a thin and dotted line to illustrate it, implying that the door can be opened and closed.

Overall, ISO 128 makes it easy for people to read and interpret technical drawings. It’s like a secret code that engineers, architects and designers use to communicate with each other without saying a word.
