CONCEPTS AND CONVENTIONS (Not for Examination) 1

Importanceofgraphicsinengineeringapplications–Useofdraftinginstruments– BIS conventions
and specifications–Size, layout and folding of drawing sheets– Lettering and dimensioning.
Basic Geometrical constructions.

UNIT I PLANE CURVES AND FREE HAND SKETCH 11
Curves used in engineering practices: Conics–Construction of ellipse, parabola and
hyperbola by eccentricity method– Construction of cycloids, Construction of involutes of
square and circle–Drawing of tangents and normal to the above curves.
Visualization concepts and Free Hand sketching: Visualization principles –Representation of
Three Dimensional objects – Layout of views- Freehand sketching of multiple views from
pictorial views of objects

UNIT II PROJECTION OF POINTS, LINES AND PLANE SURFACE 12
Orthographic projection- principles-Principal planes- projection of points. First angle
projection - Projection of straight lines inclined to both the principal planes –
Determination of true lengths and true inclinations by rotating line method- Projection of
planes (polygonal and circular surfaces) inclined to both the principal planes by rotating
object method.

UNIT III PROJECTION OF SOLIDS 12
Projection of simple solids like prisms, pyramids, cylinder and cone when the axis is inclined
to one of the principal planes by rotating object method.

UNIT IV PROJECTION OF SECTIONED SOLIDS AND DEVELOPMENT OF
SURFACES 12
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.

UNIT V ISOMETRIC, PERSPECTIVE PROJECTIONS AND FREEHAND
SKETCHING 12
Principles of isometric projection–isometric scale–Isometric projections of simple solids and
truncated solids - Prisms, pyramids, cylinders, cones-
Perspective projection of simple solids-Prisms, pyramids and cylinders by visual ray
method.
TOTAL: 60 PERIODS
OUTCOMES:
On Completion of the course, the student will be able to
