Below you will find some professional diagrams drawn by two inventors. Inventors have to take on the role as product designers at times. A diagram is not the same thig as a sketch. A sketch would be considered a DRAFT within the diagramming process. Diagrams are not only visual pictures but also labels. Diagrams also require product designers to show multiple perspectives of a product. Imagine a microscope and how "Close-up" a microscope allows a viewer to see. Then picture a globe. A globe shows a person everything the earth has on its surface from landmasses to bodies of water. Product designers use both perspectives to educate their customers. Take a look at the examples below. I took these photos while at the National Archives in Washington D.C.
