Abstract
A good example of the manual vs. digital divide in design process is the studio modelling process. On one hand, the manual clay modelling offers the much needed tangibility and adds a touch-and-feel quality, whereas the digital clay offers flexibility and accuracy. This paper attempts to (a) analyze various options covering the manual to digital spectrum (b) devise a scientific criterion to evaluate them and (c) conclude the best option. After calculating weighted quality level for each function the results showed that overall value addition is best in digital route due to the head-start it gets in the first step, where 3D sketching provides the best advantage in terms of detection and quantification. In subsequent stages, the manual-digital route adds best values, due to the mix of qualities of digital and forward routes. This results in a hybrid option (3D sketch to virtual reality to hard clay) which offers the best value addition. A dispassionate evaluation of all options is needed to get the best mix of new and traditional and this study has attempted to objectively explore the best mix of digital and tangible processes to optimally exploit the advantages of all processes.
