Representational Techniques for Architecture [PDF ebook] 

Representational Techniques for Architecture (2nd edition) explores the techniques used to represent architectural design. It describes a broad array of methodologies for developing architectural ideas, ranging from two- and three-dimensional conceptual sketches, through to the working drawings required for the construction of buildings. It offers a range of practical drawing methods, showing how to present and plan layouts, make conceptual sketches, work with scale, use collage and photomontage to create contemporary images, along with techniques to prepare and plan design portfolios.The book also deals with contemporary computer modelling and drawing techniques.
Students and practitioners will find this a clear and useful companion to a vital aspect of architectural design.Thirty per cent of the material in the second edition will be new: many of the images will be replaced, new text will be added and existing text updated.
The second edition includes explanations of the most up-to-date CAD technology and illustrations showing how it can be used to create architectural models and plans. Additional case studies will be drawn from American and international architectural practices and studios in order to attract the US market.The enhanced project sections encourage students to explore further the techniques that they have acquired.
