Engineering Drawing, Introduction to drawing equipment and use of instruments. Symbols
and conventions in drawing Practice. Types of lines and their use, BIS codes for lines,
Technical lettering as per BIS codes, Introduction to Dimensioning, Concepts of scale in
drawing, Types of scales. Basic Definition of geometrical objects: Points, lines, planes and
solids.

2. Theory of Projections - Relevance of projection, Type of projections, Perspective,
Orthographic, Axonometric and their basic principles, System of orthographic projection:
in reference to quadrants and octants, illustration through simple problems of projection.

3. Projection of Points- Projection of points in quadrants and octants. Projection of point on
Auxiliary planes.

4. Projection of Lines -Parallel to both H P and V P, Parallel to one and inclined to other,
and inclined to both, contained in profile plane. True length and angle orientation of
straight line: rotation method and auxiliary plane method. Distance between two
nonintersecting lines, and trace of line.

5. Projection of Planes- Difference between plane and lamina. Projection of lamina Parallel
to one and perpendicular to other, Perpendicular to one and inclined to other, Inclined to
both reference planes, and Lamina oblique to three reference planes. Application of
auxiliary planes, and trace of planes.

6. Projection of Solids- Definition of solids, types of solids, and elements of solids.
Projection of solids in first or third quadrant, with axis parallel to one and perpendicular
to other, axis parallel to one inclined to other, axis inclined to both the principle plane,
axis perpendicular to profile plane and parallel to both H P and V P. Visible and invisible
details in the projection. Use rotation and auxiliary plane method to draw the projections.

7. Section of Solids Definition of Sectioning and its purpose. Procedure of Sectioning,
Types of sectional planes. Illustration through examples.

8. Development of Surface Purpose of development, Parallel line, radial line and
triangulation method. Development of prism, cylinder, cone and pyramid surface for both
right angled and oblique solids, and development of surface of sphere.

projection, Difference between isometric projection and isometric drawing. Isometric
projection of solids such as cube, prism, pyramid and cylinder, and assignments on
isometric projection of simple machine parts.
10. Orthographic Projection Review of principle of Orthographic Projection, Sketch/drawing
