Various planes of projection considered in orthographic projection have been presented in such a manner that they can be easily visualized which is essential in solving the problems using orthographic projection.
Rules for obtaining projections have been derived from the presented theory behind them, and have been used wherever needed to make the readers understand the steps involved in solving a particular problem.
All different options available to solve a particular problem have been discussed as far as possible.
The illustrative examples along with typical illustrative examples make the subject clearer.
Multicolour illustrations using specific colours for specific features throughout the book make the readers understand the illustrations very clearly and easily.
Text utilizes its own notations and abbreviations which avoid repeated use of long terms.
