Sketching elevations in design – Drawing, sketching and designing (11/19)


Activity 7 is producing
some simple views of the cardboard model of the chair
we produced earlier on in Activity 3. The three views I want to produce
are the side view, the front view and the plan. So let me sketch out approximately
what I’m going to be doing. I want to sketch onto my gridded
paper the side elevation. Now we could either copy this from
the drawing given in Activity 3 or we could measure it
from the actual model itself. That’s going to be the view on there. I also want to produce the front view and that’s going
to appear about there. That’s that view. I also want to produce the plan and that’s going to be a view
down to here. So this is my side view, this is going to be my front view and this is going to be my plan view. Side, front and plan. Now I need to get another sheet
of paper, measure my model and begin drawing
a more accurate drawing of this. Okay, so I’ve got
all the dimensions down now. I’ve got my side view, I’ve got
the basis of my front view and I’ve got the basis
of my plan view. You can see I’ve begun to show
the thickness of the cardboard at the sides onto here. I need to show the seat and back and because I’ve been able
to take the model and measure it, I can convert that dimension
onto the front view and I can use that to project across
to give me the base of here. So we’re going to use that dimension
to project across to give myself a line onto here. That’s how high
that seat point is going to be. I now need to measure
how far that comes out onto here. So you can either take again the
dimension from the modelling workbook or measure your cardboard model. And mine measures 30mm,
let’s put a point on here. The front of the seat is 45,
that’s 35mm high and convert that dimension up here
and put a point in. Now I’ve got the front of the seat, the base of the seat
and the top of the back. I can draw those in to here and onto here and I can show
the thickness of the card, just estimating it
for the purpose of this one. It’s rather thick in my pen but
you’ll be using a thinner pen, an ordinary Biro
would be quite adequate to show that. So you can see that’s the view now
looking on the side of that seat. I can project this dimension across – that’s the beauty
of this sort of drawing, you can project dimensions
from one drawing to another one rather than have to measure it
every time in every drawing. And the same now for the back,
I can draw in the back here. In fact we’re only going to see just
the edge of the back of that seat. I now need to produce
a dimension for the back and I can do that
by taking it from this dimension. I can measure it from here to here
which is 30. Produce that onto there,
draw that in, and finally the front edge
of the seat which cuts across there. So this line along here is the ground that the side view and the front view
are resting on but I can also give more information
in the form of a plan. And this type of drawing is very helpful if you’re trying to
communicate information in design.
