LESSON 2 STARTER
Learning objective: Learn how to draw and annotate observational sketches of existing
products. Sketch and draw moving products to develop communication skills.
METHODS OF DRAWING & SKETCHING
Drawing and sketching is a fun way to be creative. Everyone can draw and sketch. And with
practice, you can start to draw things you see around you and recreate them on paper with
surprising accuracy. If you are confident, you can then move on to drawing designs for
things you can’t see, but are new ideas you have had yourself. This is how designers start
every project, with quick sketches on paper to show others (clients and fellow designers)
before committing any valuable time to making models or bringing the ideas to life on the
computer (CAD). Today you will start by sketching 2D features and profiles of Hexbugs, then
move onto 3D sketching aspects of them. Once you have mastered these steps, you can
then move onto sketching your own ideas…
New words: client, CAD.
Drawing & Communication
How to sketch Hexbugs in static positions
Designers are able to communicate ideas through
pencil and paper very quickly and effectively. Those
that are good at drawing something they can picture
in their mind will practice and practice to develop
this skill (its not something that you either can or
cannot do).
Most common starting points would be to use a HB
pencil (it gives you lots of different tones of grey
depending on how hard you press) and a bleed
proof paper (so that if you come to colour or render
the image, the ink will not seep outside the lines)
Designers…practice sketching their ideas.
New words: render, tone.

Drawing & Communication
How to start sketching: features
These sketches are of the wheels of a Hexbug Larva.
Notice how there is detail in the holes, and how
some of the sketches have created “pale” lines to
show that features are divided into 3 equally (see
below) and also how small arrows show the
direction of spin.
Drawing & Communication
How to start sketching – side views
2D sketches (2 dimensions) are a great starting point
for all new designers. This is where you can only
view the product from one side, and can only give it
two measurements (a length and width).
Shown right is a sketch sheet for the Hexbug Larva.
As you can see the sketches start as 2D, and only at
the bottom right do they start moving in to 3D.
New words: 2D, 3D, length, width.
Drawing & Communication
Task: Draw 2D features and profiles of a Hexbug
Select a Hexbug from those on offer and set it in front of you at your desk.
Decide what side you want to draw, or what feature you are interested in.
Good designers draw big, and fill their page with ideas leaving few spaces.
This is your challenge today…
Here is an example of a Nano which
has been drawn from the top, the
red part has been drawn from the
side, and the battery lid has been
drawn close up, all in 2D, with as
much detail as possible. The pupil has
filled up the A4 sheet too!
New words: transparent.
Drawing & Communication
Examples of good practice
Here are some photos of work produced by 11 year old pupils. Consider how they
have set their work out; as large as possible; accurately with a ruler; and with detail!
New words: transparent.
LESSON 2 PLENARY
As a class, let us consider the following questions?
A. How do designers build up their sketches?
B. Why do designer sketch in detail?
C. What do designers use rulers for?
D. Why do we have the saying “a picture paints a thousand words”?
Summary
Learning objective: Learn how to draw and annotate observational sketches of existing
products. Sketch and draw moving products to develop communication skills.
Today you have:
 Learnt how to study and draw existing products in 2D.
 Developed knowledge of designers draw
 Practiced drawing Hexbugs in detail to prepare for designing your
own.
