AIM

To develop graphic skills in students.

OBJECTIVES

To develop in students graphic skill 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) 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 15

Curves used in engineering practices:

Conics – Construction of ellipse, Parabola and hyperbola by eccentricity method –

Construction of cycloid – construction of involutes of squad and circle – Drawing of

tangents and normal to the above curves.

Free hand sketching:

Representation of Three Dimensional objects – General principles of orthographic

projection – Need for importance of multiple views and their placement – First angle

projection – layout views – Developing visualization skills through free hand

sketching of multiple views from pictorial views of objects.

UNIT II PROJECTION OF POINTS, LINES AND PLANE SURFACES 14

Projection of points and straight lines located in the first quadrant – Determination of

true lengths and true inclinations – Projection of polygonal surface and circular

lamina inclined to both reference planes.

UNIT III PROJECTION OF SOLIDS 15

Projection of simple solids like prisms, pyramids, cylinder and cone when the axis is

inclined to one reference plane by change of position method.

UNIT IV SECTION OF SOLIDS AND DEVELOPMENT OF SURFACES 15

Sectioning of above solids in simple vertical position by cutting planes inclined to one

reference plane and perpendicular to the other – Obtaining true shape of section.

Development of lateral surfaces of simple and truncated solids – Prisms, pyramids,

cylinders and cones – Development of lateral surfaces of solids with cylindrical

cutouts, perpendicular to the axis.

UNIT V ISOMETRIC AND PERSPECTIVE PROJECTIONS 15

Principles of isometric projection – isometric scale – isometric projections of simple

solids, truncated prisms, pyramids, cylinders and cones.

Perspective projection of prisms, pyramids and cylinders by visual ray method.

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.

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

3. 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.

4. Whenever the total number of candidates in a college exceeds 150, the

University Examination in that college will be conducted in two sessions (FN

and AN on the same day) for 50 percent of student (approx) at a time.
