TECHNICAL DRAWING

Why do we draw?

To communicate!!!

Why does it matter?

What’s the use of a great idea if you cant convey it to any one else. No one is an expert at everything, so we must collaborate to reach a common goal.

Picture is worth a 1000 words!!!

In the real world you have to collaborate, so you

need to know how to communicate your ideas

or they are not very useful to you

WORDS are pretty effective for some situations,

often in Engineering and design, pictures are much

more effective.

Importance of communication

What’s the worth of your ideas if you cant share

it with others?

Communication with Drawing

(things to consider)

Subject – what you are trying to convey

(Process, structure, function, material,

etc….)

Audience – who you are communicating

with

(designer, client, manager, public, other

engineers)

Types of Technical Drawing

Drawing types

◦ Sketches

◦ Isometric Drawings

◦ Orthographic Projections

When is a sketch useful?

Think about

◦ What (subject)

◦ Who (audience)

Sketching – look and feel

Sketching – to show process

Sketching – to explore form

Sketching

usually

associated

with look

and feel,

try and

emphasize

that other

models are

at times

effective.
