Art – Using sketching effectively in design: Drawing, sketching and designing (1/19)

Activity 18 is called
Sketching Complex Objects. And the complex object I’ve chosen to
represent is this child’s toy. It’s not so complicated that it makes it
very difficult to draw, but it does give me a chance
to represent much of the things we’ve looked at, the crating, the ovals,
the use of outlining and perspective. So, where do you start
with an object like this? Well, we need to decide what sort of
view we’re going to produce, first of all. And, if you remember back
to some of the previous activities, it was up to us what sort of box
we started with. There’s the Y shape I started with. But I could represent it
in a very different way. I could represent it like this. I saw much more of that top surface. The way I draw it is entirely up to me, as the graphic designer
of this particular image. So, having thought about it, I’ve decided that I particular want to be
able to see the top, and the side, I like the wheels very much, but I want to be able to see this front
surface, as well. So, I need to produce a crate which
envelopes the entire object. Now, it might be that I chose to spend
some time measuring this object, to get it exactly understood. And just, for the purpose of this
sketch activity, I’m just going to go straight in
and produce a shape like that, which more or less envelopes
the whole of the object. Clearly there’s wasted space up here,
but let’s see how that unfolds. I know that the object has a thinner front
than the back, so I need to begin to put in some of this
shape over here. And I’m beginning to construct now
the front nose of the tractor. And I’m using my crate guidelines to
help me construct the basic shapes that appear
in this tractor form. The roof is going to come over
something like that. It’s going to come about there. And the wheel is going to be about
there. Let’s put in one of the wheels. Now, remember the principle of drawing
these ovals was to find the axis. And I’ll put that in as a construction
line there. And, at 90 degrees to it,
I put in a line, which will be the major axis. And I’m going to use that to help me
construct a line like that. That’s a representation using an oval
that represents the circle of the wheel. And I’ll do the same for the front wheel,
let’s see how that would look. I have a look at this, I can see it’s just
beneath the underside there. It seems to go through a little sort of
plastic housing there. I draw in the axle.
I draw a line 90 degrees to it. And I allow that to become
the guidelines of my ellipse, my oval. So, I can now project those lines out
and draw another oval, because I want the wheel to have
some thickness. And the same for the front wheel. Join that up to there.
Let’s put some of those lines in. So, you can see what it is. And we can begin to continue
with this now. It looks like my original crate was a little
bit ambitious at the back there. It’s not a problem, because I’m
just going to foreshorten that a little bit. And obviously I’ve got my funnel
coming out of here. And how are we doing for that? Right, we need to put in some
back wheels – sorry, some wheels at the rear of that. I can’t quite see the other one. And those little headlight things on here. I’m not going to put too much detail
into this sketch. This, after all, is a first sketch, that I can now use as an underlay, using
that overlay technique. So, now we’ve got a sketch of our child’s
toy, which is a plausible starting point. But it’s used many of the techniques that we’ve developed
in this modelling workbook. The idea of crating, to help us establish
a perspective. The use of guidelines, to help us get
accurate ovals for things like wheels. The use of shading to give
three-dimensional form to an object. If you can end up with rough sketches
like these, then they’re going to be really valuable
to you, not only in communicating the design
ideas, amongst other designers, and showing them to other people, but the act of visualising them
to improve your own creativity. So, these are the techniques that you
need to practise to be able to use sketching effectively
in design.
