I Year B.Tech.


UNIT – I
INTRODUCTION TO ENGINEERING DRAWING : Principles of Engineering Graphics and their Significance
– Drawing Instruments and their Use – Conventions in Drawing – Lettering – BIS Conventions. Curves used
in Engineering Practice & their Constructions :
a) Conic Sections including the Rectangular Hyperbola – General method only.
{Ellipse,Parabola,Hyperbola,Rectangular Hyperbola}
b) Cycloid, Epicycloid and Hypocycloid
c) Involute.
d) Scales: Different types of Scales, Plain scales,Diagonal scales,vernier scales, comparative scales, scales of chords.

UNIT – II
DRAWING OF PROJECTIONS OR VIEWS ORTHOGRAPHIC PROJECTION IN FIRST ANGLE
PROJECTION: Principles of Orthographic Projections – Conventions – First and Third Angle, Projections of
Points and Lines inclined to both planes, True lengths, traces.

UNIT – III
PROJECTIONS OF PLANES & SOLIDS: Projections of regular Planes, auxiliary planes and Auxiliary
projection inclined to both planes. Projections of Regular Solids inclined to both planes – Auxiliary Views.

UNIT – IV
SECTIONS AND SECTIONAL VIEWS:- Right Regular Solids – Prism, Cylinder, Pyramid, Cone – Auxiliary views.

DEVELOPMENT AND INTERPENETRATION OF SOLIDS: Development of Surfaces of Right, Regular
Solids – Prisms, Cylinder, Pyramid Cone and their parts. Interpenetration of Right Regular Solids

UNIT – V
INTERSECTION OF SOLIDS:- Intersection of Cylinder Vs Cylinder, Cylinder Vs Prism, Cylinder Vs Cone.

UNIT - VI
ISOMETRIC PROJECTIONS : Principles of Isometric Projection – Isometric Scale – Isometric Views–
Conventions – Isometric Views of Lines, Plane Figures, Simple and Compound Solids – Isometric Projection
of objects having non- isometric lines. Isometric Projection of Spherical Parts.

UNIT –VII
TRANSFORMATION OF PROJECTIONS : Conversion of Isometric Views to Orthographic Views –Conventions.

UNIT – VIII
PERSPECTIVE PROJECTIONS : Perspective View : Points, Lines, Plane Figures and Simple Solids,
Vanishing Point Methods (General Method only).
