ME-101 Engineering Graphics 

Engineering Graphics/Technical Drawing –a Visual Science. Types of Engineering Drawing, Introduction to drawing equipment and use of instruments, Application of 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 drawing, Types of scales.

Theory of Projections:
 Relevance of projection, Theory 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.

Projection of Points: 
Projection in quadrants and octants, Projection of point on auxiliary planes. Projection of Lines: Parallel to both H P and V P, Parallel to one and inclined to other, Contained in profile plane, Other typical cases: three view projection of straight lines, true length and angle orientation of straight line: rotation method and auxiliary plane method, Distance between two non-intersecting lines, trace of line.

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, Plane oblique to three reference planes, application of auxiliary planes, trace of planes.

Projection of Solids:
 Definition of solids, types of solids, and elements of solids, Projection of solids in first or third quadrant, 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 of rotation and auxiliary plane method.

Section of Solids:
 Definition of Sectioning and its purpose, Procedure of Sectioning, Illustration through examples, Types of sectional planes-application to few examples. Intersection of Surfaces/Solids: Purpose of intersection of surfaces, Intersection between the two cylinder, two prisms, prism and pyramid, pyramid and pyramid, cylinder and prism, cone and cylinder, sphere and cylinder etc., use of cutting plane and line method.

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, Development of surface.

Isometric Projection:
 Classification of pictorial views, Basic Principle of Isometric projection, Difference between isometric projection and drawing, Isometric projection of solids such as cube, prism, pyramid and cylinder, Discussion on isometric projection of simple machine parts. Orthographic Projection: Review of principle of Orthographic Projection, Examples of simple machine aprts, Drawing of Block and machine parts.
