Hello BTech First Year students, "Engineering Graphics" is an important subject in the first year of a Bachelor of Technology (B.Tech) program. It aims to provide students with a comprehensive understanding of engineering drawings and their applications. The course covers various topics, including orthographic projections, isometric projections, sectioning, dimensioning, and tolerancing. It introduces students to the concepts of visualization, sketching, and drafting, which are essential for producing accurate and concise engineering drawings. The course emphasizes the use of computer-aided design (CAD) tools and software, which are widely used in engineering applications.
The subject also covers various standards and conventions for engineering drawings, such as the International Organization for Standardization (ISO) and American National Standards Institute (ANSI). The course enables students to communicate their ideas and designs effectively using engineering drawings. It also helps students develop their problem-solving skills and ability to analyze and interpret engineering drawings. By the end of the course, students will have gained a solid foundation in engineering graphics, which will be useful in their future studies and careers in various fields of engineering.
I am sharing the Engineering Graphics PDF class lecture notes, eBook, book as per the BTech First Year course syllabus. This is a common subject for all engineering students and these Engineering Graphics quick revision notes will help you score more marks and help study in less time.

- UNIT 0: Importance of Engineering Graphics – use of drawing instruments. BIS Conventions, specifications, layout of drawings, Lettering and dimensioning
- UNIT I: PLANE CURVES AND INTRODUCTION TO ORTHOGRAPHIC PROJECTION (Curves used in Engineering Practices): Construction of Ellipse, parabola and hyperbola by eccentricity method only. Construction of CYCLOID, INVOLUTE OF SQUARE AND CIRCLE only. Drawing normal and tangent to the above curves.
- UNIT II: PROJECTION OF STRAIGHT LINES AND PLANES [FIRST ANGLE]: Projection of straight lines, situated in first quadrant only, inclined to both horizontal and vertical planes – LOCATION OF TRACES ONLY. Determination of true length and true inclinations of straight lines from the projections (not involving traces) Projection of plane surfaces like rectangle, square, pentagon, hexagon, circle- surfaces inclined to one reference plane.
- UNIT III: PROJECTION OF SOLIDS AND SECTION OF SOLIDS: Projections of prism, pyramid, cone and cylinder, axis inclined to one plane by change of position method. Section of above solids in simple vertical position (axis perpendicular to HP alone) by planes either inclined to HP or VP alone- True shape of section.
- UNIT IV: DEVELOPMENT OF SURFACES AND ISOMETRIC PROJECTION: Development of lateral surfaces of vertical prism, cylinder pyramid, and cone truncated by surfaces of inclined to HP alone. Development of surfaces of vertical cylinder and prism with cylindrical cut outs perpendicular to the axis. Isometric projection of solids like prism, pyramid, cylinder and cone; combination of any two; truncation when solid is in simple vertical position, by a cutting plane inclined to HP.
- UNIT V: FREE HAND SKETCHING AND PERSPECTIVE PROJECTION: Free Hand sketching of front view, top view and a suitable side view of simple components from their isometric views. Normal perspective of prism, pyramid, cylinder & cone in vertical position by visual ray method only.
