Learning Objectives:
 ALL will understand the term Exploded Level 4
 MOST will be able to draw in Exploded Level 5
 SOME will accurately apply presentation
skills to your drawings Level 6
Homework :
Find out what a vector graphic is
Begin by drawing the
centre edge of your
shape. Draw it
vertically up the page.
Then work away
from the line,
drawing lines up
at 30 degrees.
Put the two
side lines in,
making sure
they are
vertical.
Connect the top two
edges by working at 30
degrees again. They
should meet exactly.
This drawing shows the shape
in more detail than the oblique
projection.


Remember the spider rule and apply thick
and thin lines around each shape to make
them look even more 3D
Add holes to your shapes and apply thick and
thin line rule

Light tone
Mid tone
Dark tone

EXPLODED ISOMETERIC PROJECTION
Designers use ‘exploded’ views, often drawn in isometric projection, to show parts of products
that are hidden from sight. For example, look at the following examples to see how this works
With exploded isometric projection, all the parts are in line with each other, along a centre line.
This is drawn precisely through the centre of the product being drawn.
With a normal isometric drawing, all the parts are in their assembled positions. This means that
vital hidden detail cannot be seen.
Designers also use exploded views to explain their designs to clients/customers
and manufacturers. Furthermore, exploded views of products are often supplied
to customers, who in turn assemble the product. A good example of this is 'knock
down' furniture. When the flat pack is opened, an instruction sheet or booklet
explains how the furniture is assembled, often in the form of isometric exploded
views.
The drawings seen below, were supplied with an instruction booklet. They are
two of numerous diagrams drawn in isometric projection. They help explain how
the cabinet and all its component parts are assembled, to form the finished
product.
These are accurate drawings constructed by a designer, that explain how the
product he/she has designed is assembled.
