ME1101 - ENGINEERING GRAPHICS
Concepts and conventions
Importance of graphics in engineering applications – Use of drafting instruments – BIS
conventions and specifications – Size, layout and folding of drawing sheets – Lettering and
dimensioning.
15
UNIT I PLANE CURVES AND FREE HAND SKETCHING
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.
15
UNIT IV SECTION OF SOLIDS AND DEVELOPMENT OF SURFACES
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.
15
UNIT V ISOMETRIC AND PERSPECTIVE PROJECTIONS
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.
