This book contains what we consider to be the "basics" of Engineering Drawing. Orthographic Projection, Conventions, Sectioning, Pictorial Representation and Dimensioning have been covered in detail as we feel that a thorough understanding of these topics forms a sound foundation upon which to build.
All technical information, examples, exercises and solutions have been compiled in accordance with the latest "metric" drawing office standards - B.S. 308:1972.
The book has not been written for any specific course but can be profitably used both by students being introduced to Engineering Drawing and also by those who have acquired a little knowledge of the subject and wish to consolidate and increase their understanding by working through carefully graded exercises.
It should prove useful for Craft, Technician (T.E.C.), O.N.D., C.S.E. and G.C.E. students and also for those H.N.D. and Degree students with little drawing experience.
The book is seen primarily as a student self-educator though no doubt many teachers will find it useful as a reference source and/or exercise "bank" .
Topics have been presented in a similar manner wherever possible. Generally the opening page introduces the topic, the next imparts the basic facts - visually rather than verbally wherever possible.
An illustrative example is provided to aid understanding and this is followed by a series of carefully graded exercises.
We are well aware of the dangers of presenting exercises which are known to contain errors. They have been included because in our experience they are the common misconceptions among students of engineering drawing.
In all cases the correct method and answers are given, some- times immediately following the example, or in the solutions at the end of the book.
It must be emphasized that this book not only transmits information it is also a work-book. Do not be afraid of drawing and writing on the pages! If maximum benefit is to be derived from the book then the old maxim, "I do and I understand" must be the students' guide.
We thank those people whose observations and suggestions have helped us improve upon the first edition of the book. We also wish to thank the British Standards Institution for allowing, usf to use extracts from B.S. 308:1972.
There are many different ways of communicating ideas, information, instructions, requests, etc. They can be transmitted by signs or gestures, by word of mouth, in writing, or graphically.
In an industrial context the graphical method is commonly used, communication being achieved by means of engineering drawings.
If oral and written communication only were used when dealing with technical matters, misunderstandings could arise, particularly in relation to shape and size.
The lack of a universal spoken language makes communication and understanding even more difficult because of the necessity to translate both words and meaning from one language to another.
However, the universally accepted methods used in graphical communication through engineering drawings eliminate many of these difficulties and make it possible for drawings prepared by a British designer to be correctly interpreted or "read" by, for example, his German, French or Dutch counterpart.

Equally important, the components shown on the drawings could be made by suitably skilled craftsmen of any nationality provided they can "read" an engineering drawing.
Conventionally prepared engineering drawings provide the main means of communication between the "ideas" men (the designers and draughtsmen) and the craftsmen (machinists, fitters, assemblers, etc.).
For the communication to be effective, everyone concerned must interpret the drawings in the same way. Only then will the finished product be exactly as the designer envisaged it.
To ensure uniformity of interpretation the British Standards Institution have prepared a booklet entitled BS 308:1972, Engineering Drawing Practice .
Now in three parts, this publication recommends the methods which should be adopted for the preparation of drawings used in the engineering industry.
The standards and conventions in most common use and hence those required for a basic understanding of Engineering Drawing are illustrated and explained in this book.
