The course should enable the students to:
I. Understand the basic principles of engineering drawing and construction of curves used in
II. Apply the knowledge of interpretation of projection in different quadrants.
III. Understand the projections of solids, when it is inclined to both planes simultaneously.
IV. Convert the pictorial views into orthographic view and vice versa.
V. Create intricate details of components through sections and develop its surfaces.
FUNDAMENTALS OF ENGINEERING DRAWING, SCALES AND
Introduction to engineering drawing: Drawing instruments and accessories, types of line, lettering
practice and rules of dimensioning, geometrical constructions, basic geometrical shapes; Scales: Types
of scales, units of length and their conversion, construction of scales, plain scale, diagonal scale, vernier
scale; Curves used in engineering practice and their constructions; Conic sections, construction of
ellipse parabola and hyperbola, special curves, construction of cycloid, epicycloids, hypocycloid and
ORTHOGRAPHIC PROJECTION, PROJECTION OF PLANES
Orthographic projection: Principles of orthographic projections, conventions, first and third angle
projections, projection of points, projection of lines, lines inclined to single plane, lines inclined to both
the planes, true lengths and traces; Projection of planes: Projection of regular planes, planes inclined to
one plane, planes inclined to both planes, projection of planes by auxiliary plane projection method.
UNIT-III PROJECTION OF SOLIDS
Projection of solids: Projections of regular solid, prisms, cylinders, pyramids, cones.
Solids inclined to one plane, solids inclined to both planes, projection of solid by auxiliary plane
UNIT-IV DEVELOPMENT OF SURFACES, ISOMETRIC PROJECTIONS
Development of surfaces: Development of lateral surface of right regular solids, prisms, cylinders,
pyramids and cones; Isometric projections: Principle of isometric projection, isometric scale, isometric
projections and isometric views, isometric projections of planes, prisms, cylinders, pyramids, and
TRANSFORMATION OF PROJECTIONS
Transformation of projections: Conversion of isometric views to orthographic views and conversion of
orthographic views to isometric views.
