Only a mind opened to the quality of things, with a habit of discrimination, sensitized by experience and responsive to new forms and ideas, will be prepared for the enjoyment of this art. The experience of the work of art, like the creation of the work of art itself, is a process ultimately opposed to communication as it is understood now. What has appeared as noise in the first encounter becomes in the end message or necessity, though never message in a perfectly reproducible sense. You cannot translate it into words or make a copy of it which will be quite the same thing.
Two-dimensional plans or sections can be seen with sketches and more diagrammatic marks all on the same piece of paper in what appears a confusing jumble.’ These sound like Gordon’s ‘wonder plots’. The architects also use their drawings as a means of thinking ‘aloud’, or ‘talking to themselves’, as Gordon put it. For example, Lawson reports the architect Richard MacCormac as saying, ‘I use drawing as a process of criticism and discovery’; and the engineer-architect Santiago Calatrava as saying, ‘To start with you see the thing in your mind and it doesn’t exist on paper and then you start making simple sketches and organizing things and then you start doing layer after layer.... it is very much a dialogue.’
The common elements in these similar descriptions are the use of drawing not only as a means of externalising cognitive images but also of actively ‘thinking by drawing’, and of responding, layer after layer and view after view, to the design as it emerges in the drawings. These observations also confirm Schön’s observation of designing as a ‘reflective conversation’ between the designer and the emerging design. It is the reliance on drawing, and the preference for the immediacy of the interaction and feedback that manual drawing gives, that makes the architects, like Gordon Murray, unenthusiastic about CAD as a conceptual design tool.
