It has become fashionable in many architectural circles to declare the death of hand drawings. What has happened to our profession, and our art, to cause the end of our most powerful means of conceptualizing designs to our clients?
The computer, of course. With its tremendous ability to organize and present data, the computer is transforming every aspect of how architects work, from sketching their first impressions of an idea to creating complex construction documents for contractors. For centuries, the noun “digit” (from the Latin “digitus”) has been defined as “finger,” but now its adjectival form, “digital,” relates to data. Are our hands becoming obsolete as creative tools? Are they being replaced by machines? And where does that leave the architectural creative process?
Today architects typically use computer-aided design software with names like AutoCAD and Revit, a tool for “building information modeling.” Buildings are no longer just designed visually and spatially; they are “computed” via interconnected databases.
I’ve been practicing architecture since 1964, and my office is not immune. Like most architects, we routinely use these and other software programs, especially for construction documents, but also for developing designs and making presentations. There’s nothing inherently problematic about that, as long as it’s not just that.
Architecture cannot divorce itself from drawing, no matter how impressive the technology gets. Drawings are not just end products: they are part of the thought process of architectural design. Drawings express the interaction of our minds, eyes and hands. This last statement is absolutely crucial to the difference between those who draw to conceptualize architecture and those who use the computer.
Of course, in some sense drawing can’t be dead: there is a vast market for the original work of respected architects. I have had several one-man shows in galleries and museums in New York and elsewhere, and my drawings can be found in the collections of the Metropolitan Museum of Art, the Museum of Modern Art and the Cooper-Hewitt.
But can the value of drawings be simply that of a collector’s artifact or a pretty picture? No. I have a real purpose in making each drawing, either to remember something or to study something. Each one is part of a process and not an end in itself. I’m personally fascinated not just by what architects choose to draw but also by what they choose not to draw.
For decades I have argued that architectural drawing can be divided into three types, which I call the “referential sketch,” the “preparatory study” and the “definitive drawing.” The definitive drawing, the final and most developed of the three, is almost universally produced on the computer nowadays, and that is appropriate. But what about the other two? What is their value in the creative process? What can they teach us?
The referential sketch serves as a visual diary, a record of an architect’s discovery. It can be as simple as a shorthand notation of a design concept or can describe details of a larger composition. It might not even be a drawing that relates to a building or any time in history. It’s not likely to represent “reality,” but rather to capture an idea.
These sketches are thus inherently fragmentary and selective. When I draw something, I remember it. The drawing is a reminder of the idea that caused me to record it in the first place. That visceral connection, that thought process, cannot be replicated by a computer.
The second type of drawing, the preparatory study, is typically part of a progression of drawings that elaborate a design. Like the referential sketch, it may not reflect a linear process. (I find computer-aided design much more linear.) I personally like to draw on translucent yellow tracing paper, which allows me to layer one drawing on top of another, building on what I’ve drawn before and, again, creating a personal, emotional connection with the work.
