A biased history of CAAD


In A biased history of CAAD¹ Alexander Koutamanis traces a bibliographic history of CAAD, positing that it emerges from two distinct ambitions: 1) a bottom-up technology-driven evolution of architectural computer graphics; and 2) a top-down domain of theory-minded design automation; including a subcategory of the previous two emphasizing computerization of analysis and evaluation. Results of the analysis are summarized in the above timeline, indicating parallel approaches during the broad adoption of CAAD in the 1980s, and a diversification during the democratic and populist 1990s, ranging from support, computational theory and collaborative projects with other specialisms. Algorithmic Architecture² by Kostas Terzidis shares a similar point that architectural computing is framed by two conditions: 1) bottom-up design realized through abstracted high level programming, i.e. computerization processes already conceptualized in the designer’s mind which are entered, manipulated or stored on a computer; and 2) top-down design realized through little or lower level programming, i.e. computation processes which apply scripting languages available in 3D packages like Maya Embedded Language (MEL), 3dMaxScript and FormZ 4.0.  While valid arguments can be made for all architects to have a broader understanding of computation in general, I would argue that the algorithmic approach is merely a shift towards an extreme formalist grammar. In fact on closer inspection, much of the recent work conceived using such methods has a recognizably visual bias of surface over space. In contrast to web and product design which seems more concerned with how things feel rather than look, architectural theory on the other hand remains trapped in a formalist cul-de-sac, conditioned by an increasingly formulaic geometricism. While I would agree with Terzidis that CAAD’s graphical interface incurs significant constraints on ideation (a view many design educators would share) a paradigm shift is unlikely unless a radical new way of interfacing with computer graphics is developed. Until this happens, computational architecture will remain largely faithful to its formalist roots.

The death of drawing


Fabien Girardin‘s Sketching with Data for the Louvre Museum using visual programming environment Impure by Bestiario

Debates on the effects of drawing technologies have been in circulation since the emergence of design education in the mid C19, specifically Dyce’s objections to the pervasive bias of life drawing (Bell, 1963). Despite a fleeting renaissance in drawing, visualization researcher Pam Schenk notes that promoting the benefits of drawing to students has become increasingly problematic. In a recent letter to Tracey, Schenk confirms that due to increased applications of digital media over the past two decades, design graduates lack critical drawing skills. Schenk’s studies into the habits of print, textile and industrial designers over a 20 year period concluded that drawing ‘remains at the centre of the creative and developmental process of design’ for two key reasons; a) to support conceptualization and b) to facilitate communication.¹

Optimizing conceptual and communicative media is clearly important, and drawing skills have remained fundamental in developing some of the latest collaborative visualization tools – e.g. Dorta’s Hybrid Ideation Space, however the emerging fields of environmental informatics and visual programming (above) suggest that as creative design processes become more mediated, intelligent and complex, it may be only a matter of time before traditional modes of sketching become virtually redundant, as Bill Mitchell suggested more than two decades ago.² Citing Mark Burry‘s 1997 paper ‘Narrowing the Gap Between CAAD and Computer Programming’ Boeykens and Neukermanns recognize the need to assign visual programming equal weight within the architectural curriculum:

…the relation between programming and design studio assignments is still non-existent in many schools, nowadays… Programming should be part of the main architectural skills, albeit not necessarily in the sense of writing code…’³

Arguments for architects to adopt visual programming (e.g. via Bentley’s Generative Components and Rhino’s Grasshopper3D) are not new. Algorithmic Architecture by Kostas Terzidis (2006) similarly praised the benefits of the computational interface. However, as Flusser reminds us in The Shape of Things: a philosophy of design (Reaktion Books, 1999) a reciprocal dependency remains: ‘the robot only does what the human being wants, but the human being can only want what the robot can do’ (p.48). While I would agree that architectural graduates desperately require a minimum of computational knowledge, the visual programming bias of systems like the ones mentioned above still reduce architects to ‘functionaries’ of their own tools. The nature of the GUI is what needs to be challenged, not the design process itself. This is the fundamental mistake design theorists routinely make when adopting computer metaphor as cognitive model (Dorst, 2007).

Crowdsourcing and its transformative effects
on design pedagogy and practice

Despite the growth of mobile computing orienting designers towards more human-centered ambitions, architecture remains fragmented and constrained by Vitruvian formalisms (left). Similarly, design computation (CAD), while offering sophisticated capabilities across a range of design disciplines, continues to entrain specialist production at the expense of generating ideas and acquiring knowledge. In response, businesses are increasingly turning to crowdsourcing networks such as Wikipedia and Facebook for design innovation and research, blurring traditional boundaries of creative authorship and shifting theory further from practice than ever.

Nevertheless, we argue that crowdsourcing has the potential to revolutionize practice. In an effort to show its transformational benefits, a 3-part strategy is proposed: 1) a review of design pedagogy and its effects on ideation and knowledge; 2) case study analyses of crowdsourcing architecture through the lens of Maslow’s ‘hierarchy of needs’ (right); and 3) the staging of a design experiment to reveal ideation variances between traditional and networked scenarios. Findings aim to confirm the benefits of crowdsourcing networks for both creative exploration and knowledge acquisition, pointing to advantages such models may provide future pedagogy.

Vitruvius Redux

The above diagram by Mark Bew of BuildingSmart and Mervyn Richards of CPIC shows the evolution from what may now be called ‘traditional’ CAD (Computer Aided Drafting) to an integrated and interoperable Building Information Model (BIM or iBIM). The benefits of editing drawings and schedules from within a single unified database offers clear advantages for many aspects of production from construction to post-occupancy. However, while growth in BIM usage has been noted (up to 80% in some cases), the reality is that not all parties elect to use the same tools. With Revit functioning as the primary BIM platform, many other parametric (Digital Project and Rhino) and feedback (Ecotect, Fluent and Simulex) tools are employed to further enable cost reductions.

Such evolutionary transferrence of information from designers to producers (builders) creates significant challenges to the traditional role of the architect as visionary leader, particularly in terms of design ideation. Yet the key advantage of BIM remains centred on its capacity to integrate lifecycles of social interaction, a shift which earlier CAD modelling simply failed to deliver. While early promises of an architectural revolution by W. J. Mitchell and Nicholas Negroponte may have been overly optimistic, in Vitruvius Redux, Mitchell reminds us that contrary to popular belief, digital design media nostalgically clings to the past, adhering to systems of architecture which can be traced back to early C19 design theories of Durand (below) and Guadet:

…designers relied heavily upon abstract ordering devices such as grids and axes… guided by this skeleton they would then consider alternative ways to arrange the major rooms and circulation spaces. Finally, they would develop the design by deploying elements from an established vocabulary of construction elements – columns, entablatures, doors, windows, and so on… a recursive process of top-down substitution.‘¹
