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.
Architectural drawing can be divided into three types: 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…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.
With both of these types of drawings, there is a certain joy in their creation, which comes from the interaction between the mind and the hand. Our physical and mental interactions with drawings are formative acts. In a handmade drawing, whether on an electronic tablet or on paper, there are intonations, traces of intentions and speculation. This is not unlike the way a musician might intone a note or how a riff in jazz would be understood subliminally and put a smile on your face.
