The preparation of plans for the construction of buildings and machines is as old as written history.Original drawings were carved on rock or sketched onto papyrus. One of the oldest drawings of anengineering component is a cave painting of a bow in Castellon, France in about 8000BC.

As civilisation grew and the skills became more advanced, plans were produced on other mediums suchand bark and paper using a variety of instruments to assist in creating better quality drawings.
