00:00:00.816 --> 00:00:03.316 A:middle
>> This is a tutorial
on lab number 15.

00:00:03.316 --> 00:00:05.206 A:middle
A lab on solid modeling.

00:00:05.206 --> 00:00:07.036 A:middle
The first thing you
want to do probably is

00:00:07.036 --> 00:00:11.686 A:middle
to change our workspace from
drafting and annotating --

00:00:11.726 --> 00:00:16.886 A:middle
annotation -- to
basic, 3D basics.

00:00:17.116 --> 00:00:18.676 A:middle
And then we create layers.

00:00:18.676 --> 00:00:19.676 A:middle
I've created layers.

00:00:19.676 --> 00:00:22.066 A:middle
Here's the layer,
layer property manager.

00:00:22.466 --> 00:00:25.406 A:middle
We have created a
construction layer that's white,

00:00:25.406 --> 00:00:28.916 A:middle
an object layer that's blue,
an object layer that's .3.

00:00:30.176 --> 00:00:33.376 A:middle
And we close that
layers property manager.

00:00:33.376 --> 00:00:41.756 A:middle
And then we turn on some of
our tabs here, drafting aids.

00:00:41.966 --> 00:00:51.926 A:middle
So the grid, the snap, and also
polar and also object snap.

00:00:52.536 --> 00:00:55.696 A:middle
And then we set the
current layer to object.

00:00:55.696 --> 00:00:57.286 A:middle
Forgot to do that.

00:00:58.106 --> 00:01:03.456 A:middle
And then we'll change our
view to SE isometric.

00:01:03.456 --> 00:01:06.816 A:middle
So we can see the
model as it's being created.

00:01:06.816 --> 00:01:08.696 A:middle
We start by creating a box.

00:01:09.486 --> 00:01:14.016 A:middle
First corner is at the
origin, 0 comma 0 comma 0.

00:01:14.476 --> 00:01:22.286 A:middle
And then second point is
4.5 comma 3.5 comma 0.

00:01:23.546 --> 00:01:26.086 A:middle
And then we are going to
work on the bottom part

00:01:26.086 --> 00:01:28.966 A:middle
and the thickness or the
height of that is .75.

00:01:29.446 --> 00:01:31.606 A:middle
Let's zoom in.

00:01:33.056 --> 00:01:35.286 A:middle
And we create another box

00:01:35.286 --> 00:01:40.896 A:middle
on the left side using
this as the first corner.

00:01:41.206 --> 00:01:44.046 A:middle
And the second corner
will be at --

00:01:44.176 --> 00:01:46.116 A:middle
make sure that it's
relative coordinates --

00:01:46.116 --> 00:01:50.626 A:middle
at 1 comma 3.5 comma 0.

00:01:52.256 --> 00:01:58.976 A:middle
Enter. And the height
of that box is 1.95.

00:02:03.046 --> 00:02:08.106 A:middle
Which is the overall
2.7 minus .75.

00:02:08.756 --> 00:02:09.946 A:middle
The thickness of the bottom.

00:02:10.506 --> 00:02:13.166 A:middle
Now we're going to union
combine these 2 solids

00:02:13.166 --> 00:02:14.706 A:middle
by using the union command.

00:02:15.486 --> 00:02:18.216 A:middle
This one and this one.

00:02:19.106 --> 00:02:19.996 A:middle
Press enter.

00:02:20.206 --> 00:02:23.906 A:middle
And notice, now, the two have
been combined to a single solid.

00:02:24.886 --> 00:02:28.886 A:middle
Next thing we're going to do is
create a box somewhere out here,

00:02:28.886 --> 00:02:32.806 A:middle
an arbitrary location outside
the solid that we have so far.

00:02:33.376 --> 00:02:34.436 A:middle
Here's the first corner.

00:02:34.546 --> 00:02:39.016 A:middle
And second corner is at 1 comma
1 comma 0 because we're --

00:02:39.666 --> 00:02:41.066 A:middle
and the height is also 1 --

00:02:41.066 --> 00:02:43.296 A:middle
because we're doing
a 1 by 1 by 1 box.

00:02:43.426 --> 00:02:48.066 A:middle
And then move this using the
midpoint of the small box

00:02:48.096 --> 00:02:51.936 A:middle
to the midpoint of this
edge of the existing solid.

00:02:53.316 --> 00:02:54.716 A:middle
So that's the correct location.

00:02:54.716 --> 00:02:58.006 A:middle
And then we subtract
the bigger one.

00:02:58.546 --> 00:03:01.266 A:middle
Enter. The smaller one.

00:03:01.506 --> 00:03:06.626 A:middle
Enter. Let's turn off our gird
so we can see this better.

00:03:07.576 --> 00:03:10.096 A:middle
Next thing we're
going to do is, again,

00:03:10.256 --> 00:03:13.446 A:middle
on some arbitrary
location, let's create a box

00:03:14.306 --> 00:03:17.186 A:middle
and the first --
second location is

00:03:17.186 --> 00:03:24.666 A:middle
at coordinates 1.5 comma 1.1, 0.

00:03:25.256 --> 00:03:29.086 A:middle
And the height is .75.

00:03:29.086 --> 00:03:32.126 A:middle
And we're going to
create a cylinder.

00:03:33.886 --> 00:03:40.116 A:middle
OK. With center is at the
midpoint of this lower left edge

00:03:40.116 --> 00:03:42.386 A:middle
of this tiny box right here.

00:03:43.606 --> 00:03:47.546 A:middle
And the radius is .55.

00:03:48.206 --> 00:03:50.496 A:middle
And the height, again, is .75.

00:03:50.616 --> 00:03:54.306 A:middle
The same height as the box.

00:03:54.716 --> 00:03:56.826 A:middle
So we've created this.

00:03:56.826 --> 00:03:58.866 A:middle
And then we're going
to union these two,

00:03:59.106 --> 00:04:01.186 A:middle
the cylinder and this box.

00:04:01.836 --> 00:04:02.866 A:middle
Press enter.

00:04:02.866 --> 00:04:09.146 A:middle
And then we're going to
move that solid there.

00:04:09.576 --> 00:04:10.546 A:middle
Press enter.

00:04:10.916 --> 00:04:13.196 A:middle
Here's the first base
point to the midpoint.

00:04:13.196 --> 00:04:16.476 A:middle
The second base point is
 midpoint of this.

00:04:16.876 --> 00:04:20.096 A:middle
Then subtract from
the bigger one.

00:04:20.096 --> 00:04:21.146 A:middle
Press enter.

00:04:21.386 --> 00:04:22.406 A:middle
Object subtract.

00:04:22.886 --> 00:04:23.826 A:middle
The smaller one.

00:04:25.006 --> 00:04:28.126 A:middle
Next thing we're going to do
is we're going to chamfer.

00:04:30.366 --> 00:04:34.206 A:middle
So chamfer at the
edge over here.

00:04:34.986 --> 00:04:37.646 A:middle
And then we select
distance as the option.

00:04:37.646 --> 00:04:42.486 A:middle
For the first distance
we type 1 comma --

00:04:42.536 --> 00:04:44.956 A:middle
and the second distance is .6.

00:04:45.776 --> 00:04:47.706 A:middle
And press enter twice.

00:04:47.706 --> 00:04:49.086 A:middle
That completes the chamfer.

00:04:49.086 --> 00:04:52.686 A:middle
And repeat the chamfer command
on this other edge here.

00:04:53.486 --> 00:04:56.416 A:middle
Now since our distance
is already set correctly,

00:04:56.416 --> 00:04:58.096 A:middle
we just press enter twice.

00:04:58.776 --> 00:05:00.066 A:middle
And we're done with that.

00:05:00.626 --> 00:05:03.666 A:middle
And then we're going to --

00:05:03.666 --> 00:05:06.526 A:middle
oh, repeat the chamfer
command again.

00:05:07.046 --> 00:05:12.226 A:middle
This time I'm going to chamfer
this edge here at the bottom.

00:05:12.376 --> 00:05:15.896 A:middle
I'll click on distance
again to reset the distance

00:05:15.896 --> 00:05:24.466 A:middle
as distance 1 is equal to
.6 and distance 2 is 1.5.

00:05:24.746 --> 00:05:25.446 A:middle
Looks correct.

00:05:25.526 --> 00:05:26.726 A:middle
Press enter twice.

00:05:27.246 --> 00:05:28.756 A:middle
Repeat chamfer again.

00:05:29.296 --> 00:05:32.216 A:middle
This time, this corner
-- this edge here.

00:05:32.866 --> 00:05:36.046 A:middle
The distance is already
set to press enter twice.

00:05:36.886 --> 00:05:38.316 A:middle
Next thing we're going
to do is we're going

00:05:38.316 --> 00:05:39.196 A:middle
to create the cylinder.

00:05:39.196 --> 00:05:43.246 A:middle
In order to do that, we need
to change using three points.

00:05:43.246 --> 00:05:46.676 A:middle
Here's the origin, is
the point on the x-axis.

00:05:46.676 --> 00:05:48.556 A:middle
And this is the point
on the y-axis.

00:05:48.556 --> 00:05:51.426 A:middle
Take note that x-y plane
is now on the left plane.

00:05:51.476 --> 00:05:53.106 A:middle
Now we're going to
create a cylinder.

00:05:54.016 --> 00:05:55.546 A:middle
And the coordinates
of the center

00:05:55.546 --> 00:06:04.616 A:middle
of the cylinder are half the
depth, which is 1.75 comma --

00:06:05.766 --> 00:06:10.296 A:middle
and it's going to be
at the height of 1.1,

00:06:10.416 --> 00:06:15.666 A:middle
which is 2.7 minus
1.6 and z of zero.

00:06:16.966 --> 00:06:17.856 A:middle
And this is the center.

00:06:17.856 --> 00:06:20.376 A:middle
And the radius is .25.

00:06:21.346 --> 00:06:24.286 A:middle
And the height of
the cylinder is 1.

00:06:25.086 --> 00:06:29.006 A:middle
And then we're going to
subtract from the big solid.

00:06:29.156 --> 00:06:30.046 A:middle
Press enter.

00:06:30.356 --> 00:06:31.286 A:middle
Object to subtract.

00:06:31.666 --> 00:06:32.666 A:middle
The small cylinder.

00:06:33.896 --> 00:06:34.656 A:middle
We're done.

00:06:34.736 --> 00:06:38.066 A:middle
Now we can look at different
ways of visualizing it.

00:06:38.556 --> 00:06:40.226 A:middle
So I'm going to go to visualize.

00:06:40.666 --> 00:06:44.356 A:middle
I'm going to use realistic.

00:06:45.456 --> 00:06:47.836 A:middle
OK. That's the realistic.

00:06:49.256 --> 00:06:51.826 A:middle
And we can orbit it.

00:06:51.826 --> 00:06:52.786 A:middle
So we can look at it.

00:06:53.796 --> 00:06:57.916 A:middle
And let's try another
visualization style here.

00:06:58.306 --> 00:06:59.316 A:middle
Conceptual.

00:06:59.316 --> 00:07:02.496 A:middle
And let's rotate again.

00:07:03.256 --> 00:07:06.906 A:middle
Looks like we're done.
