GE8152 Engineering Graphics First Semester Syllabus 2013

GE8152 ENGINEERING GRAPHICS

(Common to all branches of B.E. / B. Tech. Programmes)

OBJECTIVES

To develop in students, graphic skills for  communication of  concepts, ideas and  design of
engineering  products  and  expose  them  to  existing  national  standards  related  to technical
drawings.

Concepts and conventions (Not for Examination)
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

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

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 true inclinations by rotating line method and trapezoidal
method and traces Projection of planes (polygonal and circular surf aces ) inclined to both the principal planes by rotating object method.

UNIT  III PROJECTION OF SOLIDS

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

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

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 solidsPrisms, pyramids and cylinders by visual ray method and vanishing point method.

COMPUTER AIDED DRAFTING (DEMONSTRATION ONLY)

Introduction to drafting packages and demonstration of their use.
