GE6152                               ENGINEERING GRAPHICS                                     L T   P  C                                                                                                                             2  0  3  4

OBJECTIVES:

• To develop in students, graphic skills for communication of concepts, ideas and design of

Engineering products.

• T o expose them to existing national standards related to technical drawings.

CONCEPTS AND CONVENTIONS (Not for Examination)                                              1

Importance   of   graphics   in   engineering   applications   –   Use   of   drafting   instruments   –  BIS conventions and specifications – Size, layout and folding of drawing sheets – Lettering and dimensioning.

UNIT I             PLANE CURVES AND FREE HAND SKETCHING                                5+9

Basic Geometrical constructions, Curves used in engineering practices: Conics – Construction of ellipse, parabola and hyperbola by eccentricity method – Construction of cycloid – construction of involutes of  square and  circle  – Drawing of tangents and normal to  the above  curves, Scales: Construction of Diagonal and Vernier scales.Visualization concepts and Free Hand sketching: Visualization principles –Representation of Three Dimensional objects – Layout of views- Free hand  sketching of multiple views from pictorial views of objects

UNIT II            PROJECTION OF POINTS, LINES AND PLANE SURFACES              5+9

Orthographic projection- principles-Principal planes-First angle projection-projection of points. Projection of  straight lines (only First angle projections) inclined to both the principal planes – Determination of true lengths and t ru e inclinations by rotating line method  and traces Projection of planes  (polygonal and circular su rf a ce s ) inclined to both the principal planes by rotating object method.

UNIT III           PROJECTION OF SOLIDS                                                                 5+9

Projection of simple solids like prisms, pyramids, cylinder, cone and truncated solids when the axis is inclined to one of the principal planes by rotating object method and auxiliary plane method.

UNIT IV   PROJECTION OF SECTIONED SOLIDS AND DEVELOPMENT OF SURFACES                                                                                                                                       5+9

Sectioning of above solids in simple vertical position when the cutting plane is inclined to the one of the principal planes and perpendicular to the other – obtaining true shape of section. Development of lateral surfaces of simple and sectioned solids – Prisms, pyramids cylinders and cones. Development of lateral surfaces of solids with cut-outs and holes

UNIT V           ISOMETRIC AND PERSPECTIVE PROJECTIONS                                6+9

Principles  of  isometric projection  –  isometric  scale  –Isometric projections of   simple solids and truncated solids – Prisms, pyramids, cylinders, cones-   combination of two solid objects in simple vertical positions and miscellaneous   problems. Perspective  projection  of  simple  solids-Prisms, pyramids and   cylinders by visual ray method .

COMPUTER AIDED DRAFTING (Demonstration Only)                                                 3

Introduction to drafting packages and demonstration of their use.

TOTAL : 75 PERIODS

OUTCOMES:

On Completion of the course the student will be able to

• perform free hand sketching of basic geometrical constructions and multiple views of objects.
• do orthographic projection of lines and plane surfaces.
• draw projections and solids and development of surfaces.
• prepare isometric and perspective sections of simple solids.
• demonstrate computer aided drafting.

###### Special points applicable to University Examinations on Engineering  Graphics:

1 .There will be five questions, each of either or type covering all units of the syllabus.

All questions will carry equal marks of 20 each making a total of 100.

1. The answer  paper  shall  consist  of  drawing  sheets of  A3  size  only.  The students will be permitted to use appropriate scale to fit solution within A3  size.
2. The examination will be conducted in appropriate sessions on the same day
