Architects have for their activities of drawing, writing and building always depended upon the potential of particular tools –ranging from practical instruments such as straight edges, French curves, compasses, rulers and pencils to conceptual tools such as working drawings, collages, photographic surveys, infographics, diagrams, casts and mass models. As technologies advanced the toolbox of architects has changed and expanded. Today architects have an extraordinary array of sophisticated tools at their disposal but also rely on many of same tools as their 18^th and 19^th century peers. Working drawings, pencils and tracing paper continue to appear in the designer’s studio while their role and potential is being redefined.
