INTRODUCTION Graphic/universal language
1.1 Impotence of Technical Drawing
Imagination: What do you think
You will need for a better life style in this century.
What kind of house will you need? What kind of car will you drive?
What magic will your computer?
If you stretch your imagination you can start thinking
about how things will be designed in the future.
All designs need creative imagination.
Communication: 9/2
Drawing is a method to describe
with lines without words.
Someone has said “a picture is
worth 10,000 words”
The carvings on the ancient temples
of Egypt serve to tell a story – astory without words.
It is the graphic language.
Mother of Engineering.
Language of Industry/universal
language.
Gift of creative imagination is more
important than all technology.
Technology is the result of creative
researchers, Engineers and Designers
thinking about what will be neededtomorrow and beyond.
Idea – How you can tell to others.
Talk, write or draw a picture.

1.2 Language of Engineering Terminology
In industry design ideas communicated
through special kind of technical drawing
process called drafting.
To show his description and size,
specification, it is easy to describe
through drawing than written description.
Imagination & communication lead to
innovation.
One new Product leads to the
development of others.
Such products are called spin-offs.
Gear, cam, rotating shafts Propellers
and turbine engines have the
modification of wheel.
Begins idea in the mind of Engineer ordesigner.
Birth of idea, sketch the 1st concept.
Designer and Engineer gives a sketch
to other members of design team.
Change the original design to make
it more practical.
Design refined or improved through
the ideas of several peoples.
Especially useful in Architecture(Perspective)
Clients evaluate design for style form &
function.
These drawing must be complete so that
the estimators can figure the exact cost of
a Project.
Factory Superintendent can know
exactly how a product is to be made.
People who use the drawings should not
have to guess about details or askquestions.
Inventor is a creator who gives the idea.
Engr. sees its technical physibility and

Complicated or unclear thoughts with
a free hand sketch. Ideas imagined in the mind can be
caught in sketch and thus hold in
simple lines for further study.
Importance/Reasons for sketching
Most important points for sketching
26/2
Ask Questions.
1- Simplest form of drawing.
2- Quickest ways to express ideas.
Language of sketching has four basic visual
symbols (things that can be seen)
These are a point, a line, a plane and a
texture(surface quality)
1. To persuade people that an idea is a good.
2. To develop a refined sketch of a proposed
solution to a problem.
3. To clarify a complicated detail.
4. To give design ideas to drafters.
5.
To develop a series of ideas for refining anew Product.

155/1, 130/2
The Prefix “multi” means that a member of views
is required to completely describe the object.
8.5 Planes of Projection 133/2
8.6 Orthographic methods of Projections.
Method of representing the exact form of an
object in two or more views on planes usually at
right angles to each other by lines drawn
perpendicular from the object to the planes.
An engineer who designs machines or products
must describe them completely and clearly so
that other people can make them.
Engineer/Architect makes a mental image of
object and then sketches its shape & size.
A Plane is an imaginary flat surface that has no
thickness. Orthographic projection involves the
use of three planes Vertical plane, H.P, P.P.
V.P. and H.P. divided space into 4 quadrants.
“Ortho” mean straight or at right angle.
“Graphic” mean written or drawn.
It is Latin words.
Pro-meaning “forward” and ejection meaning
“to throw”.
Orthographic Projection literally mean thrown
forward drawn at right angle.

8.9 Multi view drawing or Multi view projection.
Multi means a number of views required to
completely describe the object “Projection”
comes from the word project which mean “to
throw forward”.
The older, more technical name for the method is
orthographic projection. Ortho mean at right
angle and projection mean drawn.

Engineer & Architect makes a mental image
of object.
Then sketches or draws several views to
accurately describe its shape & size.

for use in manufacturing & construction.
To understand multi view drawing, consider
an object beyond a piece of glass. You look
at the object through the glass and view one
side at a time
You keep your line of sight perpendicular to the
glass.

other people.
Multi view drawing shows geometric shapes
of the product & their relationships.
However drawing must also show the exact
size & relationship of those geometric
shapes in a precise & acceptable manner.
Show the size of the object.
Show the location of any part in the object.
Used to show the relative positions of the

Full size layout of an object made on a single
flat plane called surface Development.
Surface:-A surface is a geometric magnitude having two
dimensions.(L,W).
It may be generated by a line called
generatix of the surfaces.
Any position of the generatix is an element
of the surface.
Parallel line development is simple way of
making a pattern by drawing the edges of an
object as parallel lines.
Example: Cylinder, Prism.
In the patterns for prisms & cylinders the

11.3.3)Triangulation:-
(Diving a surface into a number of Triangles and
transferring them to the development)
Example: Oblique Pyramid and Oblique cone.
lines (vertical construction lines) are
perpendicular to it and parallel to each other.
On cones & pyramids however the edges are
not parallel.
Example: Cone .Pyramids.
Triangulation is a method used for making
approximate developments of surfaces that
can’t be developed exactly. It involves dividing the surface into triangles.

Three dimensional geometrical figures are
called solids.
1. Cone
2.
Cylinder
3. Prism
4. Pyramid
Solids bounded by plane surfaces are G .S
Cone, is generated by a straight line called the
generatix, moving in contact with a curved line
and passing through a fix point, the vertex of
the cone. Each position of the generatix is anelement of the cone.
Cylinder is generated by a straight line, called
generatix, moving in contact with a curved line
and always remaining parallel to its previous
position or to the axis. Each position of the
generatix is called an element of the cylinder.
Prism, Solids made by principal line-having top
and base in same shape and size called prism.
OR
Solids bounded by plane surfaces called Prism.
Pyramid, is a polygon for a base and triangular
lateral faces intersecting at a common point
called vertex.
If the axis is perpendicular to the base it is calledright pyramid otherwise it is an oblique
pyramid
