GE 9111 ENGINEERING GRAPHICS L T P C
(Common to All branches of B.E. / B.Tech. Programmes) 2 0 3 4
OBJECTIVES:
To develop in students the graphic skills that would enable them to communicate the
concepts, ideas and design of engineering products
To provide an exposure to the national/international standards related to technical
drawings
8
INTRODUCTION 2
Importance of graphics in engineering applications – use of drafting instruments – BIS
specifications and conventions – size, layout and folding of drawing sheets – lettering
and dimensioning
UNIT I FREE HAND SKETCHING OF ENGG OBJECTS AND
CONSTRUCTION OF PLANE CURVE 3+9=12
Pictorial representation of engineering objects – representation of three dimensional
objects in two dimensional media – need for multiple views – developing visualization
skills through free hand sketching of three dimensional objects.
Polygons & curves used in engineering practice– methods of construction– construction
of ellipse, parabola and hyperbola by eccentricity method – Cycloidal and involute
curves- construction - drawing of tangents to the above curves.
UNIT II ORTHOGRAPHIC PROJECTION: PROJECTION OF POINTS, LINES
AND PLANE SURFACES 6+9=15
General principles of orthographic projection – first angle projection – layout of views –
projections of points, straight lines located in the first quadrant – determination of true
lengths of lines and their inclinations to the planes of projection – traces – projection of
polygonal surfaces and circular lamina inclined to both the planes of projection
UNIT-III ORTHOGRAPHIC PROJECTION: PROJECTION OF SOLIDS AND
SECTIONS OF SOLIDS 6+9=15
Projection of simple solids like prism, pyramid, cylinder and cone when the axis is
inclined to one plane of projection –change of position & auxiliary projection methods-
sectioning of above solids in simple vertical positions by cutting plane inclined to one
reference plane and perpendicular to the other and above solids in inclined position with
cutting planes parallel to one reference plane – true shapes of sections
UNIT IV DEVELOPMENT OF SURFACES AND INTERSECTION OF SOLIDS
6+9=15
Need for development of surfaces – development of lateral surfaces of simple and
truncated solids – prisms, pyramids, cylinders and cones – development of lateral
surfaces of the above solids with square and circular cutouts perpendicular to their axes.
Intersection of solids and curves of intersection –prism with cylinder, cylinder & cylinder,
cone & cylinder with normal intersection of axes and with no offset.
UNIT V ISOMETRIC AND PERSPECTIVE PROJECTIONS 4+9=13
Principles of isometric projection – isometric scale – isometric projections of simple
solids, truncated prisms, pyramids, cylinders and cones – principles of perspective
projections – projection of prisms, pyramids and cylinders by visual ray and vanishing
point methods.
