“Ah, I see what you didn’t mean” Exploring Computer Aided Design tools for design ideation

It is often claimed that Computer Aided Design ( CAD) tools are unsuitable for design ideation as they are said to not support serendipitous interpretation, playfulness and creativity. However, this notion is based on anecdotal evidence and research that was done using CAD tools now considered obsolete. This study therefore aims to provide insights on the use of currently available CAD tools for design ideation. This was done by having three experts evaluate the use of pen- and- paper sketches and four different CAD tools for design ideation and discuss the results. The results from this study suggest that CAD tools have the potential to support serendipity and provide an environment for creativity and playfulness. There are several opportunities for the use of CAD tools in design ideation. This is certainly true in design fields where it is notoriously hard to make sketches, such as in lighting design.
