This chapter aims to give the student studying mechanical engineering design the foundations for producing engineering drawings that are to be used in the manufacture of an engineering artefact or component. Technical Product Documentation is the term used by the International Standards Organisation (ISO) to describe the whole area of design communication, covering the information sufficient for the manufacture of a product and can be described in a number of ways including traditional paper-based drawings. There are a number of different types of engineering drawings, each of which meets a particular purpose. Engineering drawings are prepared on standard-size drawing sheets. The sheet sizes are based on the ISO sheet sizes. Engineering numbers should be a unique identifier for a specific engineering drawing. The lettering style is an important part of engineering drawing. It gives information regarding size and instructions in the form of notes and dimension.
