At E&PDE08, the authors presented a paper that demonstrated links between the use of computeraided design (CAD) when designing and a 'creative behaviours model' derived from published research into creativity; primarily from researchers in the field of cognitive psychology. From a series of data collection approaches e.g. observations, protocol analysis, and design diaries, designers were found to display a number of creative behaviours whilst using CAD in designing [1]. Inevitably a key question arises as to how such creative behaviours relate to the behaviours observed when designers use other designing tools such as 2D and 3D sketch modelling. This paper will report the authors' initial research concerning this parallel agenda. Literature reviews have been undertaken of reported categories of behaviours observed when 2D and 3D sketch modelling and a sample design project has been carried out. This provided data for an initial comparative analysis with the 'creative behaviours model' previously used in analysing CAD modelling. Again protocol analysis and design diaries were employed to record behaviours from 2D and 3D sketch modelling, and CAD modelling activities. The design project has confirmed the emergence of most of the behaviours reported in the literature in relation to 2D and 3D sketch modelling. As 2D and 3D sketch modelling are accepted as creative activities when designing, there would be every expectation of correlation between the behaviours observed when undertaking these activities and the creative behaviours model derived from cognitive psychology. An analysis of the research results has been undertaken to reveal such correlations, as well as apparent differences.
