Abstract

Mixed media design, which includes both pencil sketching and computeraided design (CAD) modelling, is frequently used in both the design industries and design schools. Research suggests that mixed media design environments provide several advantages over design environments that use singular media. Although a common outcome of CAD modelling is design documentation, researchers have argued that CAD modelling could support conceptual design. In our study four experts were invited to complete different design tasks. They were asked to sketch first and then model their designs using CAD. A Function-Behaviour-Structure coding scheme was adopted to analyse their cognitive actions. The empirical evidence collected shows that being dissatisfied with sketches resulted in the entire CAD design phase becoming uncertain. Thus, an optimal solution may not be achieved after the use of one design medium. This means that subsequent design sessions need to support designers to refine their designs by evaluating alternatives. The main contribution of this study is for teaching CAD design. A model was developed for the phenomenon of CAD modelling to support conceptual design or design documentation in mixed media design environments.
