one long box representing the neck of the
guitar. Create the boxes lightly so they can
be erased. This sketch might not look very
similar to a guitar at this stage. The look
of the guitar will come together in the next
stage, adding the outline.
Adding an Outline
The blocked-out sketch might not
look very similar to the designer’s idea.
This sketch should be, however, the
basic shape and proportion of the idea.
Designers must add details to the shapes
to make the shapes look the way they want
them to look. The first detail added is an
outline. Creating the outline might include
subtracting parts of the shapes. The guitar
in the previous example is several cylinders
and boxes. To create the outline, a designer
subtracts parts of cylinders to make the
guitar rounded. See Figure 13-21. It is
important that the blocked-out shapes are
drawn lightly because they are guidelines.
When the designers add the outline, they
draw the lines darker because these lines
will not be removed.
Drawing Design Features
The next details to be added are the
external features. The external features
are objects not included in the outline, but
ones that can be seen when looking at the
design. The number pad on a telephone
is an external feature. These features help
in understanding the sketch. The tuning
knobs, frets, and sound hole are all external
features of a guitar. See Figure 13-22.
External features also help to set designs
apart from each other. A designer might
have a number of sketches for a product
that have the same outline. The only
differences are the external features. For
Figure 13-20. A guitar is blocked out using
boxes and cylinders.
