Code: EURME 206/106 Category: BE
Credits:2 Hours : 4 per week

Department : Mech. Engg.

UNIT-I Orthographic projections and projections of points:
Introduction to Orthographic projections – First angle projection and third angle
projection. Projection of points.
Projections of straight lines:
Projections of straight lines: line parallel to one or both planes, line perpendicular to
one of the planes, line inclined to one plane, line inclined to both the planes. True
length of straight line and true angles and its traces.
UNIT-II Projections of planes:
Introduction, types of planes – perpendicular planes – perpendicular to one plane and
parallel to other plane, perpendicular to one plane and inclined to other plane, oblique
planes.
Projections on auxiliary planes: types of auxiliary planes, perpendicular to one plane
and parallel to other plane, perpendicular to one plane and inclined to other plane,
oblique planes.
UNIT-III Projections of Solids:
Introduction – types of solids – polyhedral – tetrahedron, prism, pyramid and solids of
revolution – cylinder, cone. Projection of solids – simple positions, axis inclined to
one plane and parallel to other, axis inclined to both the planes.
UNIT-IV Development of Surfaces:
Developments of lateral surfaces of right solids – cube, prisms, cylinders, pyramids
and cones.
Sections of Solids:
Introduction – section planes, sections and true shape of a section. Sections and
sectional views of solids – prism, pyramid, cylinder and cone.
UNIT-V Isometric Projections:
Introduction – isometric axes, lines and planes. Isometric scale, isometric view and
projections of solids in simple position – prism, pyramid, cylinder, cone and sphere.
