<p>With the development of digital technologies, orthographic projection has been slowly removed from the process of architectural design. Instead, orthographic projection drawings are increasingly utilised purely post-design in the form of technical construction documents. Yet, according to Robin Evans orthographic projection is an active agency in the formation of images, and an effective agency for the elaboration of imaginary objects. Furthermore, for Iain Fraser and Rod Henmi orthographic projection produces conceptually sophisticated constructs whose abstract representation of space allows certain aspects and relationship to be seen which may not otherwise be visible. This thesis argues that the reduced role of orthographic projection in the process of design has affected architects' ability to elaborate the imaginary. To investigate the potential of orthographic projection in the elaboration of the imaginary, this thesis expands upon Marco Frascari's written theory of technological images as a palimpsest displaying three overlapping relationships: (1) between a real artefact and the reflected or projected image of it, (2) between a real artefact and its instrumental image, and (3) between the instrumental image and its symbolic image. To expand upon this theory graphically this thesis employs a methodology of architectural drawing as research. Outlined by Clemens Steenbergen, this framework proposes three distinct forms of architectural drawing that constitute research. This thesis couples these three forms with Frascari's three overlapping relationships of a technological image: (1) The Reproduction Drawings aim to register more accurately how something is made up through a process which interprets the object of observation and incorporates it into memory. These drawings embody the first overlapping relationship of Frascari's, technological image, between a real artefact and the projected image of it. (2) Analytical Drawings reveal abstract qualities and potentials by reducing the complex compositions of the first series to their elementary geometric forms, lines and grids. These drawings embody the second overlapping relationship, between a real artefact and its instrumental image. (3) Experimental Drawings project the reproduction and analytical drawings into an existing context to expand upon or reinforce the relationships and conceptual connections formed in relation to the site in the preceding two series. The effects of these interventions are assessed and altered, ultimately leading to new concepts and new compositions. These drawings aim to elaborate imaginative relationships between buildings and architectural ideas, through a process Frascari terms a mutual measure derived from a familiar nature. These drawings embody the third and final overlapping relationship between the instrumental and its symbolic image. By extending upon Frascari's theory graphically, this thesis argues that orthographic projection remains a valuable tool in the process of design. The real artefact chosen to demonstrate the continued value of orthographic projection is Wellington's Civic Square. This site was selected as the buildings located around its formal rectilinear domain offer a heterogeneous mix of civic architecture, ranging from the strictly orthogonal Town Hall and City Gallery to the curvilinear Public Library and City Administration Building. This site offers the opportunity to test both the advantages and disadvantages of orthographic projection, for the reading of architecture and the elaboration of the imaginary, within a formally diverse existing urban environment.</p>
