This paper reviews the core principles of machine drawing as presented in K. Gopalakrishnan’s standard textbook. It covers projection methods, sectional views, dimensioning standards (IS:696–1972), limits and fits, surface roughness symbols, and assembly drawing practices. The paper emphasizes the role of machine drawing in conveying manufacturing details unambiguously.
Machine drawing is the universal language of engineers. Gopalakrishnan’s Machine Drawing provides a systematic approach to creating and interpreting production drawings. This paper synthesizes his key chapters into a coherent guide for students and practitioners.
Gopalakrishnan, K. (2017). Machine Drawing (3rd ed.). Vikas Publishing House.
Following first-angle projection (as per Indian standards), Gopalakrishnan details how to project three principal views: front, top, and side. Hidden edges are shown as dashed lines, and centerlines indicate axes of symmetry.

To reveal internal features, the book explains full section, half section, offset section, and revolved sections. Hatching lines at 45° distinguish cut material.
