Some may think sketching is a disappearing skill, but if you ever enter a design studio, you will find out differently.
Studios still make sketches and drawings by hand and in most cases, quite a lot of them.
They are an integral part of the decisionmaking process, used in the early stages of design, in brainstorming sessions, in the phase of research and concept exploration, and in presentation.
Drawing has proved to be, next to verbal explanation, a powerful tool for communicating not only with fellow designers, engineers or model makers but also with clients, contractors and public offices. This book can be regarded as a standard book on design sketching, useful for students in product design.
