Introduction Engineering drawing is the language of engineering. Without the knowledge of engineering drawing, an engineer is nowhere, and he could not have constructed the various magnificent structures or intricate machines. Evidently anyone connected in anyway, with engineering construction must understand this language of engineers. Technical drawing is therefore indispensable today and shell continue to be so as long as engineering and technology continue to be of use in the activities of man. The subject Engineering Graphics & Design will help the students in many ways for making images, describing the shape, size, finish, colour and construction any object. Student will learn the basic concept of orthographic projection, projection of points, lines, planes, solids, section of solids, and development of surfaces of solids and Isometric projections. He will be able to use the present drafting software. Lists of Drawing Instruments In the preparation of engineering drawing, the following drawing instruments and materials are required 1. Drawing board 2. Drawing paper/sheet (A-2 Size) 3. Mini Drafter/ Set squares (30°-60°, 45°-45°) 4. Scales (Plain, Diagonal) 5. Protractor (180°, 360°) 6. Compass (Small and Large) 7. Divider (Small and Large) 8. Drawing pencils (HB, H, 2H) 9. French Curves 10. Eraser, Sharpener, dusting cloth 11. Drawing pins & clips 12. Drawing sheet carrier.
