ABSTRACT
e subject of graphics, equipment and draftsmanship is complex, ever changing and therefore for detailed study the reader is referred to specialist works. e following passages oer an introduction to the subject. e fact also remains that much of contemporary design work is achieved these days by Computer Aided Design (CAD); it is just the initial sketch design that is better achieved by hand drawing, and a simple pencil and rubber are the primary instruments of the initial concept and sketch design process. However, in view of the fact that many senior designers lead the sketch design process and the CAD work follows on – often by other team members – it is important for the senior sketch designer to use pencil weighting (line thickness) to help others understand the pencil scrawls. It is also important for the CAD expert to understand what the dierent line weighting means and to ensure the CAD version carries forward this treatment into the nal drawing – so the client can better read and understand the drawing. Of course there are still plenty of older practitioners still using traditional pens and drawing boards, so for this reason, and the fact that on occasions it is quicker and more expressive to use hand drawing, the following passages are still included and I would urge students to read this chapter for the sake of understanding the history and background of traditional drawing techniques and how these can be interpreted in CAD drawings – to make these more expressive and readable.
