A continuing issue in industrial design education is when to allow students to move from sketch work to 3D CAD modelling during studio practice—or whether to let them use CAD at all! I’ve heard of first year undergraduate modules where students are ‘banned’ from the use of CAD in an attempt to encourage sketchbook work and more explorative conceptual design practice. In my view this approach is somewhat draconian and does little to deal with the underlying reasons that attract less experienced designers to the comparative certainty of 3D CAD.
Agile Engineering is a popular process in software development, but few hardware teams apply these practices to develop physical products. For many hardware teams, implementing Agile Engineering practices saves time and money and improves the end product.
