Using real working drawings from a 50 year career, Ron Slade shows how drawing remains at the heart of the design process in the everyday working life of engineers and architects. The book explains simple techniques that can be learnt and used to enhance any professional's natural ability. Using over 180 categorised examples it demonstrates that drawing remains the fastest, clearest and most effective means of design communication. Unlike many other books on drawing in the construction industry, this book is 'engineer led' and science oriented but effectively shows that there is a close affinity between the working methods of architects and engineers.
