| Unit 1. | ISOMETRIC PROJECTION OF SOLIDS | Construction of isometric scale showing main divisions of 10mm and smaller divisions of 1mm, also showing the leading angles. Isometric projection (drawn to isometric scale) of solids such as cube; regular prisms and pyramids (triangular, square, pentagonal, and hexagonal); cone; cylinder; sphere; hemisphere; keeping the base side of the solid parallel or perpendicular to HP/VP. The axis of the solid should be either perpendicular to HP / VP or parallel to HP and VP. |
| Unit 2. | ISOMETRIC PROJECTION OF SOLIDS | Combination of any two above-mentioned solids keeping the base side parallel or perpendicular to HP/VP and placed centrally together (Axis of both the solids should not be given parallel to HP). |
| Unit 3. | Machine Drawing (Machine Parts): Drawing to full-size scale with instruments | Drawing to full-size scale with instruments. Introduction of threads: Standard profiles of screw threads - Square, Knuckle, B.S.W., Metric (external and internal); Bolts – Square head, Hexagonal head; Nuts– Squarehead,
Hexagonal head; Plain washer; a combination of nut and bolt with or without a washer for assembling two parts together. |
| Unit 4. | Machine Drawing (Machine Parts): Free-hand sketches | Free-hand sketches. Conventional representation of external and internal threads; Types of studs – Plain stud, Square-neck stud, Collar stud; Types of rivets – Snap head, Flat head, Pan head (without tapered neck), 600 Counter Sunk Flat head. |
