By drawing, specifically we mean freehand sketching and diagramming.
She has conducted empirical studies of design drawing and constructed computer software to integrate knowledge-based applications with freehand drawing.
We sketched the panel freehand, paying particular attention to areas of fading, detail or difficulty.
These then interact with more freehand drawing, and so the process goes on.
First, in the process of solving design problems the freehand drawing is the pre-eminent tool employed by nine of the 10 architects interviewed.
These investigations by model sometimes take over as the main drivers of architectural form-making at a stage midway between freehand drawing and cad.
As one can see, despite quite freehand treatment, the analytical solution shows very good agreement with numerical one.
Even at this stage the architects interviewed undertake design modification initially via the freehand sketch.
