To develop graphic skills in students.
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
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
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
