We’ve always been a profession of hackers. Every building is a one-off made up of countless elegant hacks, each bringing disparate materials and systems together into a cohesive whole. But when it comes to the software that designers have come to rely on, most of us have been content with enthusiastic consumerism, eagerly awaiting the next releases from software developers like Autodesk, McNeel (Rhino) and Bentley (MicroStation).
It’s been 5 years since we officially launched our research program at the Yazdani Studio of Cannon Design, and during that period we’ve come to understand the evolution of our process reflects the larger, changing relationship architects have with their means of production. Specifically, we've noticed that in late 2007 something changed. McNeel introduced a visual programming plugin called Grasshopper, and more and more architects began to hack their tools as well as their buildings.
With all the buzz around bespoke products and novel technology, it’s easy to forget we still live in an off-the-shelf world. Most things aren't made-to-order and the software that designers depend on is no different. The program a Hollywood studio is using to create special effects is often the same one an architect uses to study a design idea. It makes sense for software companies to invest in developing tools that serve large market sectors. It also makes sense for small businesses to borrow tools from larger industries. But what about all those little process idiosyncrasies that make design studios unique? Chances are a general-purpose, cross-industry application isn’t going to be 100 percent compatible with the way you do things.
Since the introduction of AutoCAD in the early 80s, architects have struggled to find a comfortable way to take advantage of efficiencies promised by digital production tools without sacrificing their signature moves. In the 90s, Frank Gehry famously adapted CATIA - software that was originally developed for designing fighter jets - to enable the construction of the complex geometries the firm was trying to create. The result, Digital Project, was developed and supported by off-shoot technology company Gehry Tech. For the rest of the industry, maintaining a team of dedicated programmers, or even retaining architects that became skilled at programming, has proven difficult. Most often, artists and architects have had to choose a compromise between their design process and the functionality offered by the software available on the market. However. a new generation of visual programming tools is now giving designers an alternative: the ability to tailor their applications to the specific way they work – without the team of dedicated programming wizards.
Visual programming is part of a larger classification of tools that support end-user development (EUD). EUD is the developers' answer to the need for user customization and automation. Most popular software packages ship with a way to modify or even create functionality, and to automate repetitive tasks. Rhino has RhinoScript, Revit has DesignScript, 3dsMax has MAXscript, and Maya has MEL, just to name a few. In reality, there are only a relatively small group of actual end-users that can use these scripting languages with any proficiency, and the few that can, quickly become specialized. Fortunately, an ever expanding roster of visual programming software like Grasshopper, Dynamo, Generative Components, 3dsMax’s MCG, and Marionette for Vectorworks are giving designers access to EUD without any prior knowledge of a programming language. By removing this barrier to entry, visual programming is quickly making EUD in architecture an every-project occurrence.
The popularity of software like Grasshopper and Dynamo suggests the relationship architects have with their tools is changing. We’re moving away from passive adoption of off-the-shelf software to actively engaging in hacking these tools to better fit our design process. Can’t find a program that does what you want? Make your own. It’s a practice that has the potential to counter the industry-wide homogenization that has left many artists and designers skeptical of the benefits of design software.
There’s more to the rise of visual scripting than just customization; generative design has the potential to allow for non-linearity in production. For architects, that could mean a fundamental transformation in how we do our work. Traditionally, architectural services are delivered along a strict set of milestones. Once a phase is complete, the decisions made in that phase are cemented, and the next phase of development can begin. This process was devised in a pre-digital world and most likely implemented to protect architects from extensive re-work without the ability to charge additional fees. But what if schematic level information could be incorporated into a model late in the development process without costing the designer time or money? What if a piece of new information or a design decision could be incorporated at any point in the process? What if construction documentation could start before schematic design was complete? If an entire project is defined as a series of interconnected decisions and relationships, all of this becomes possible. In fact, it started happening the moment the industry moved away from the hand drafting mimicry of CAD software to the three-dimensional modeling approach that BIM takes. The next logical step is to abstract away the explicit placement of 3D elements in space, and define a design as a series of decisions, systems, and relationships. In the end, it’s all data, and visual scripting gives designers a way to create and manage it.
It’s exciting to see how the adoption of EUD tools will impact our industry. CAD and BIM were supposed to revolutionize the practice of architecture. Looking back, it’s difficult to argue that either has been anything more than an incremental step. Will EUD finally deliver the revolution we’ve all been waiting for?
