>> This is a video, a short video presentation illustrating
how to create multi-views using paper
and pencil, given isometrics.
This is for the first part of lab A, okay?
So we're given the isometric view on the right here,
and we're supposed to create the multi-views counting the width
of the object.
So the first thing you need
to do is create the overall boundaries of the views.
There's six -- The width is 16 inch, counting the height,
it's one, two, three four, four units for the height here,
and then for the depth, it's also one, two, three, four.
The depth is measured here.
And take note that the location of the front is always
in the middle, and there should be perfect alignment
between the width dimension between the top and the front
and the height dimension between the front and the right.
The right is always to the right of front
and the top is above the front.
So looking at the projection of the details of the object
from the isometric into the fundal plane,
the blue frontal plane and projecting each
of those corners, okay, those who create this image
on the frontal projection plane, the front projection plane
and then that horizontal line is going
to be projected along here, and then on the side here,
it will be going up to and then going all the way to the right
and then going down, and then --
So this is the projection of that U-shape right
on the frontal plane into the front projection plane
and the front view will therefore look
like this vertical line here and another vertical line here going
down only three units, two units as well
and then this is the right edge of the front.
There's the bottom edge.
Then here is the little lines for the U
and here's the middle plane, okay?
Now the back plane here, okay, will perfectly align
to the front, so it's going to be behind
that U shape in the front.
So there's nothing else for the front view except that.
Now for the top view, the skinny rectangle up here will be seen,
because that's all the way to the top, and on the other side,
there's also that skinny rectangle, okay?
And then that plane that is two units below,
that plane right there will also be seen from the top.
Okay, but this is nothing's covering it,
so that should complete the top view.
Now for the right side view, this rectangle
on the right profile plane will be seen,
or it's actually a square right here, okay?
And then, we discussed the right side view,
the plane that is halfway down right here, okay,
that plane right there, will actually be seen
as a hidden line because it's being covered
by the right plane, so it's hidden.
Take note that there's perfect alignment between the front
and the top for the width and the height
between the right and the front.
Now here's another example here.
We're given the isometric again,
so we count the width here from the isometric.
It's also six units, and then we count the height, one, two,
three, four also, so the height is four,
so the front view would be 4 by 6 and the depth will also be 4.
So the right side view will be 4 by 4.
Now starting on the front view, that skinny rectangle
of width two and height one will be shown here,
and there's another one at the bottom,
that other skinny rectangle,
and then that square that's slightly behind right there,
those two lines will actually be seen as two vertical lines here,
aligned perfectly with the skinny --
two skinny triangles in the front.
And then we will see this line above here, okay?
And also below there, and then we're going
to see the semicircle, okay?
So the semicircle will be seen right here
and right here definitely free handling the right --
the semicircle and then right here is the geometric center
of both the semicircle and the small circular hole
of radius one will be right there.
And that I believe completes the front view.
Now working on the top view now,
we will see this edge here corresponding to that
and isometric and that moves to the right by two
and it moves backwards by two also, and now we're going to see
that semicircle apart, okay, will be a straight zenith,
a straight line, because that's perfectly aligned along the same
depth, alright?
And then that limiting element will be shown here
for the curve, and then you will see the back plane
as a single line.
So those are the only visible lines.
However, you see that there's right here,
this square right here, okay,
the isometric will actually be shown as a hidden line.
It's one unit behind the frontal plane,
so it's covered by that top plane.
So those are -- That's a hidden line.
Now, let's see for the circular hole, okay,
you will see the limiting element here --
element, both on the left and the right
and hidden lines as well.
And that completes the hidden lines for the top view.
Now, let's look at the right side view.
For the right side view,
we're going to see a shape towards the front, okay.
That's the kind of inverted C-shape that we're going to see
from the right, and here's the semicircular part.
It will only appear as a rectangle, a semicircle
around the -- from the right side,
which the vertical rectangle in here are the hidden lines
for the limiting element
of the circular hole, cylindrical holes.
Take note that those two hidden lines
that I just drew should align perfectly at the same height
as the top and bottom of the circle now.
Whenever you have a circle and semicircle,
you need to indicate those locations by center line,
one on the right side view;
also one on the top view I just constructed.
And also instead of leaving the center of the circle
as just a center mark, a cross mark, we might also want
to have present it as two intersecting center lines.
The center line length type will be long- short-long and that --
