Engineering Graphics is the language for communication and documentation of engineering design. With the arrival of computers, the usage of this language has advanced into the areas of manufacturing, assembly, inspection and maintenance since all these functions are well executed through computer aided drafting (CAD) and three- dimensional modelling. Based on these developments, it is highly recommended for the students entering the engineering field to study the fundamentals of this language in their first year of the engineering course. Advanced topics in Engineering Graphics are covered in the following years according to their respective branches of study. Threedimensional objects located in space have to be converted and presented on a two-dimensional drawing sheet or monitor screen using the ISO Standard coding system. To fully understand the techniques used in this process, the student should develop good visualization capacity.

Even though there are a number of textbooks available for engineering drawing, the treatment of the subject is still found to be difficult for an average student. This book is an effort to overcome or reduce this difficulty.

The content of the textbook Engineering Graphics for Diploma is divided into seven modules. A topic is first introduced in each chapter of a module, with brief explanation and necessary pictorial views, and then mastered gradually through a number of worked-out examples. The examples are explained using a step-by-step procedure and illustrating drawings. All the drawings are prepared in First Angle Projection and strictly follow the ISO/BIS format.

Module A-Preliminaries, covers the fundamentals of manual drafting. lettering. freehand sketching and dimensioning of views. Module B describes twodimensional drawings like geometrical constructions. conics, miscellaneous curves and drawing of scales. Three dimensional drawings are well explained in Module C, starting with projections of points and then straight lines located in all the four quadrants. Projections of plane lamina. geometrical solids and sections of them are also described in detail in the same module. Module D deals with the surfaces of solids, such as intersection of surfaces and their developments.

Drawings of pictorial views of solids and objects are illustrated in Module E. These include isometric projection, oblique projection and perspective projections. The perspective view drawing presented in first angle itself avoids discontinuity in study, as compared to other available textbooks in the market. Fundamentals of machine drawing are covered in Module Fin four chapters. The last Module G introduces computer aided drafting (CAD) for producing professional level orthographic drawings. Selected questions from various Diploma Examination question papers and their solutions are also given. This enables students to prepare themselves for Diploma Examinations.

I am highly grateful to the eminent professors. teachers and earnest students of various engineering institutions for their encouragement. Their creative criticism and suggestions helped me to prepare this book in its current form. Iextend my heartfelt thanks to PHI Learning for taking interest and the effort to publish this textbook at international standards.

Acknowledgement is also due to the Bureau of Indian Standards, whose work has been consulted for the preparation of this book. I would also like to express my gratitude to various Boards of Technical Education in India, for permitting me to include their examination questions as worked-out examples.
