The computerization of the engineering office

Since the beginning of time, people later to be known as engineers and architects have strained to create methods whereby they could improve technology to assist them in their various fields of endeavour. Some of these improvements would be the change from linen paper, french chalk and ink pens to drafting film , mylar an d pencil for the production of drawings, the drafting machine in lieu of the tee and set squares, even tap e to attach drafting media to the board instead of thumb tacks and man y, man y more. All of these taken individually are insignificant but combined evolve to the current state-of-the-art in the computerized engineering environment. Ten years ago the major topic o f conversation was the hand-held calculator which for a cost of around $150 would give most trigonometric functions. Today the equivalent calculator can be purchased for around $25, is about one third the size, and if inflation were included over the last ten year s the item should cost around $550 in today' s dollars, it can be seen that tremendous advances not only in the technology but also the cost saving. The following paper is intended to outline some o f the significant aspects o f the latest technology in the computerized engineering office namely Interactive Graphics Systems.
