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.
