The 'Esquisse' is a central tool in the architetcural technologist's technical design process. At its best it is a creative process of iterative sketching, placing layer upon layer in a process of reflective questioning in which a problem is defined and a solution mapped out in a loose but clear techncial proposition. it is only after such a process that the more prcise process of drawing and modeling might commence.
