Ultimately this study will assess how this rapid and changing digital revolution has affected the process of architectural design, and whether by harnessing this change the architect can safeguard their position as a key player in the overall construction industry Owing to the technical and constantly evolving nature of this field, it is important to make clear some definitions before continuing. The term â&#x20AC;&#x2DC;digital architectureâ&#x20AC;&#x2122; can refer to a number of different meanings, and its use is often inconsistent. Most classify it into either of two definitions: any design made with the assistance of a computer, or as this becomes almost universally standard, architecture of an experimental nature outside of the mainstream sphere and pushing the envelope of computer design.2 For the purpose of this dissertation, the former definition will be used, with digital architecture referring to any design produced through the use of a computer. The umbrella term of computer-aided design (CAD) is used to refer to a broad range of digital technologies and computer programs, both dealing with two-dimensional and threedimensional virtual entities. Here, the term will be used to encompass any method by

design process. The traditional drawing techniques that now seem plainly obvious and rudimentary, such as convincing perspective, are the result of centuries of evolution in the understanding of how man sees and interacts with the world, and how this can be translated through two-dimensional media. These discoveries created the foundations for the development of the sophisticated software tools that allow such detail and accuracy in modern design, and are ubiquitous within the architecture profession today. It is also useful to examine what specific tools and processes were developed for traditional drawing techniques, and how they changed the way drawing was understood and carried out, in

! Now designers had a mathematical system to help them create drawings of geometric forms with convincing accuracy and depth, and this helped to move the practice of drawing forward. The same rules of linear perspective are still taught today, and the principles that Brunelleschi demonstrated 400 years ago are used in modern computer modelling software to produce accurate manifestations of threedimensional objects on screen. This measured, mathematical approach to constructing drawings necessitated the development of precise and accurate tools that would aid draftsmen in creating complex, and reproducible designs. After the use of the drawing board and Tsquare became commonplace in the early 18th century, the 19th century saw the development of more advanced drafting tools for specific purposes, spurred on by the Industrial Revolution and the increasing desire to make

construction and manufacturing a more efficient, higher output process. Particular geometric drawing challenges, such as constructing classical Ionic column capitals and ellipses, were addressed by the use of helicographs, ellipsographs and volutors.5 These mechanical drawing aids removed the need for complex geometric calculations to be carried out and allowed the drafter to reliably produce consistent forms. While at the time this was certainly seen as an advancement and improvement over the manual method, undoubtedly there would have been critics that claimed that the traditional techniques were being lost and eroded, much in the same way that digital architecture is being challenged today.

In order to assess the validity and usefulness of new tools and processes it is important to discuss what it is about the manual practice of drawing and designing by hand that makes it beneficial to the design process. The physiological process that allows humans to coordinate the movement of a pencil across a page is proprioception. The proprioceptive system enables the body to respond to incoming sensory stimuli of external forces and vary muscle contraction accordingly. This is achieved by making use of

traditional design an embodied act that grounds the architect in the work that they are producing. In this way there is a direct relationship between the hand, the eye and the mind of the designer: the line that is envisaged by the architect, the act of moving the hand across the page and the line that is seen to be drawn. When traditional, manual drafting is carried out at a set scale, it allows the architect to project themselves into the drawing and embody the design, therefore being able to fully understand the implications that their changes make on the scheme as a whole.7 Physical, tactile hand modelling is another way that traditionally architects have engaged their whole body in the act of designing. When handling tangible, existent models and materials, the designer has a constant awareness of the object they are observing, rotating and manipulating. They are able to unconsciously project themselves into the spaces presented, and put them in direct relation with their own body, being immediately and innately aware of the modelâ&#x20AC;&#x2122;s size and scale in relation to their own. Proprioception as a phenomenon is one that has been largely disregarded as digital technologies have been taken up by the architecture industry, and as such new discussions have arisen concerning its value and whether it is wise to try and protect it as the digital age progresses. Indeed, it is fair to assume that many will not have been aware of this idea (or seen any need to dwell on it)

! Paul Emmons has written comprehensively about his belief that the most dangerous aspect of CAD that threatens effective architectural design is the lack of a fixed, consistent scale when in the virtual realm. He claims that this goes beyond merely the technical issue of being presented with an essentially unknown scale, suggesting that it fundamentally affects the way architecture is conceived.17 In the computer, images are represented at a 1:1 scale that can be infinitely zoomed and resized. This allows virtual drawings or models to both be made so small Fig. 2 – Barcelona Vila Olimpica 'Fish' CAD models.

! same, there is no ‘hard click’ or ‘soft click’.28 Our advanced and infinitely adaptable proprioceptive system has been restricted to a mere handful of repetetive, perfunctory operations. While it is valid to question whether the computer has helped or hindered modern architectural design, it is clear that it has ushered in a new age of architecture that explores new boundaries in form making and building performance, allowing shapes and structures that would not previously been possible to be realised. The ease and speed with which designs can be edited, developed, and communicated with third parties or other designers has also accelerated the construction industry, and it is for these reasons and numerous others that it is only possible to accept that it is here to stay. A way to address the accusation that contemporary architects are merely designing ‘CAD buildings’, limited by the software capabilities and the technical skill of the operator, is to broaden the conventional methods by which designers interact with virtual space. By allowing computer technology to be harnessed in a way that does not remove the craftsman from the craft, it can be used to serve creativity and originality, rather than to control it.

! Having now discussed both the value of the haptic experience in the act of hand drawing and designing, and the removal from this after the advent of computer based systems in architectural design, it is possible to consider how new technologies are able to combine these two elements and generate new digital tools that make full use of the capabilities of computer design, while allowing a direct and intuitive way for the architect to interact with the virtual realm.

This availability would do much to dissolve the barrier between computer and user imposed by the need to learn specific program functions, and open up digital technology to even the most technically illiterate. By combining this approach with 3D printing technologies, the future architect will be able to move seamlessly between the physical and the virtual throughout the design process,

have developed a method of synthesising a virtual model with the idea that one could build a physical model in the real world, and then digitally ‘scan’ the model threedimensionally and transfer it to the computer to take advantage of digital techniques and processes. While this approach to ‘tracing’ physical models and converting into virtual objects has been used since the arrival of digital methods in architecture, new research has developed an advanced method described as ‘scalable real-time volumetric surface reconstruction’.30 This technology has the potential to enable a designer to pass a depth-

Looking at many digital tools that are available today or currently being developed, it is clear to see that as technology progresses, the capacity for digital tools to more closely emulate their traditional counterparts also increases. An example of how this is evidenced is in one of the first digital tools to be developed. Graphics tablets have been available since the early stages of CAD, and

Only the passage of time and the continued research and development into the fields discussed in this essay will reveal the ultimate direction that the architectural design process will take, and certainly many of the themes and arguments presented here will be repeated when the next advancement looks to disrupt the then established tools and techniques. Ultimately, when the ability to transition from virtual to physical becomes immediate and complete, the argument of the merits of the two will be irrelevant. They will have become so integrated and intertwined that one feeds off the other in a symbiotic relationship. It is in this direction that the process of architectural design needs to head â&#x20AC;&#x201C; where digital technology and architecture moves forward in a joint relationship, while preventing either one from dominating the other.
