How do you start to design a product? Can drawing techniques be learned? And why is modelling such a useful technique? This album introduces the basic skills necessary to communicate ideas on paper, as well as revealing the step-by-step processes for making three-dimensional models of objects, showing perspective in drawings and sketching complex objects. It also features a case study of the Strida folding bicycle, an idea taken from initial drawings to marketed product. This material forms part of The Open University course T211 Design and designing.
