Core skills enhance knowledge, analytical ability, problem solving ability, understanding or comprehending scientific principles and drawings & designs also. At the same time it creates the base for achieving Hard skills. To carry out any skill related task knowledge about basic Engineering Drawing is essential as drawing is the language of engineers

Knowledge of Engineering Drawing complements the skills of an Artisan / Trade person. More importantly, ability to read drawing increases the productivity of a person besides enhancing confidence to perform task competently.

Recognising this importance the core skills (Engineering Drawing) made an integral part of all Engineering Trades under NCVT.

The content of Engineering Drawing is common for first two semesters for all Engineering Trades having more than two semesters. The contents of 3rd & 4th semester are made trade specific to fulfill the requirement of each trade.

1. Construction of Scales and diagonal scale
2. Practice of Lettering and Title Block
3. Dimensioning practice:

• Position of dimensioning (unidirectional, aligned, oblique as per BIS SP:46-2003)
• Symbols preceding the value of dimension and dimensional tolerance.
• Text of dimension of repeated features, equidistance elements, circumferential objects.

4. Construction of Geometrical Drawing Figures:

• Different Polygons and their values of included angles. Inscribed and Circumscribed polygons.
• Conic Sections (Ellipse & Parabola)

5. Drawing of Solid figures (Cube, Cuboids, Cone, Prism, Pyramid, Frustum of Cone and Pyramid.) with dimensions.

6. Free Hand sketch of hand tools and measuring tools used in respective trades.
7. Projections:

• Concept of axes plane and quadrant.
• Orthographic projections
• Method of first angle and third angle projections (definition and difference)
• Symbol of 1st angle and 3rd angle projection as per IS specification.

8. Drawing of Orthographic projection from isometric/3D view of blocks
9. Orthographic Drawing of simple fastener (Rivet, Bolts, Nuts & Screw)
10. Drawing details of two simple mating blocks and assembled view.
