00:00:00.996 --> 00:00:03.146 A:middle
>> I'll give you a
short description

00:00:03.146 --> 00:00:05.396 A:middle
of what you're expected
to do for lab number 18,

00:00:05.396 --> 00:00:06.946 A:middle
Working Drawings and Assemblies.

00:00:07.546 --> 00:00:09.146 A:middle
The lab has 4 parts.

00:00:09.326 --> 00:00:12.796 A:middle
We are given a figure
here that --

00:00:13.216 --> 00:00:15.196 A:middle
it's an assembly that
you're supposed to create.

00:00:15.266 --> 00:00:17.226 A:middle
So for the first part
of the lab you're going

00:00:17.226 --> 00:00:19.206 A:middle
to create 3D models
for each part.

00:00:20.056 --> 00:00:22.506 A:middle
So the parts are -- you're going

00:00:22.696 --> 00:00:25.026 A:middle
to create a 3D model
for bushing.

00:00:25.436 --> 00:00:26.856 A:middle
This one -- your part number 1.

00:00:27.316 --> 00:00:30.916 A:middle
And then part number 2 is
what we're calling the base.

00:00:31.206 --> 00:00:34.266 A:middle
And part number 3 is the cap.

00:00:34.716 --> 00:00:37.936 A:middle
And then, part number 4,
although it's a standard part,

00:00:37.936 --> 00:00:41.896 A:middle
you can also create
a model for the boat.

00:00:41.966 --> 00:00:45.326 A:middle
You don't need to
show the threading.

00:00:45.476 --> 00:00:48.956 A:middle
Just show them as cylinders
because, again, we don't need

00:00:48.996 --> 00:00:52.116 A:middle
to show the details
using a standard part.

00:00:53.056 --> 00:00:56.686 A:middle
So first part is
creating 3D models

00:00:56.686 --> 00:01:01.186 A:middle
for definitely the 3
parts, base, bushing,

00:01:01.986 --> 00:01:05.426 A:middle
and cap, using AutoCAD.

00:01:06.856 --> 00:01:08.276 A:middle
Then, for the second part --

00:01:08.416 --> 00:01:10.396 A:middle
so it's going to look
something like this.

00:01:10.396 --> 00:01:13.896 A:middle
So first part would
consist of 3,

00:01:14.746 --> 00:01:17.696 A:middle
at least 3 drawings like this.

00:01:17.696 --> 00:01:22.676 A:middle
This is the 3D model
for the bushing.

00:01:22.936 --> 00:01:26.536 A:middle
So it's just a system
of cylinders added

00:01:26.536 --> 00:01:29.496 A:middle
and subtracted from each other.

00:01:29.496 --> 00:01:35.266 A:middle
And then here's the
3D model for the cap.

00:01:35.426 --> 00:01:38.526 A:middle
That's the second model you're
going to create is a 3D model.

00:01:38.566 --> 00:01:44.046 A:middle
And then one for
the base as well.

00:01:44.046 --> 00:01:46.796 A:middle
That's for the cap and
this is for the base.

00:01:46.796 --> 00:01:50.556 A:middle
And, as I said, you might
also want to create a model

00:01:51.186 --> 00:01:55.626 A:middle
for the bolt because
you're going

00:01:55.626 --> 00:01:57.896 A:middle
to need that in the assembly.

00:01:58.386 --> 00:02:01.836 A:middle
Now for the second part
of the lab you're going

00:02:01.836 --> 00:02:03.626 A:middle
to create detailed
drawings for each

00:02:03.626 --> 00:02:06.126 A:middle
of the non-standard
parts in the assembly.

00:02:06.126 --> 00:02:11.566 A:middle
So for parts 1 through 3, the
bushing, the base, and the cap,

00:02:11.896 --> 00:02:15.426 A:middle
you're going to use Solvew/Soldraw
draw to create the front,

00:02:15.496 --> 00:02:16.976 A:middle
top, and right side views.

00:02:16.976 --> 00:02:18.156 A:middle
So here's an example.

00:02:18.986 --> 00:02:23.496 A:middle
Here is part B. So
this is for the base.

00:02:23.526 --> 00:02:27.206 A:middle
So from the model that you
created, you're going to go

00:02:27.536 --> 00:02:30.256 A:middle
to the layout and
then you're going

00:02:30.256 --> 00:02:31.416 A:middle
to type Solview/Soldraw just

00:02:31.416 --> 00:02:33.696 A:middle
like the Solview/Soldraw
combination.

00:02:33.696 --> 00:02:40.616 A:middle
Follow the steps in lab
number 17, I believe.

00:02:40.886 --> 00:02:48.196 A:middle
And then you need to indicate
dimensions following the rules

00:02:48.196 --> 00:02:49.876 A:middle
for dimensioning
that we've learned.

00:02:49.876 --> 00:02:51.516 A:middle
That constitutes the part

00:02:51.586 --> 00:02:55.106 A:middle
of creating dimension
detail drawings for each

00:02:55.106 --> 00:03:00.396 A:middle
of the 3 non-standard parts, the
base, the cap, and the bushing.

00:03:00.816 --> 00:03:02.486 A:middle
And then, for the third
part, you're going

00:03:02.486 --> 00:03:04.646 A:middle
to create a pictorial
assembly of the drawing.

00:03:04.646 --> 00:03:07.986 A:middle
It's going to look
almost like this.

00:03:08.976 --> 00:03:13.526 A:middle
Where each of the parts,
standard and non-standard,

00:03:14.676 --> 00:03:19.506 A:middle
shown here with center lines
and with balloons and labels.

00:03:19.506 --> 00:03:24.656 A:middle
And also including the Bill of
Materials right here.

00:03:24.656 --> 00:03:25.596 A:middle
So it's going to look,

00:03:25.596 --> 00:03:30.406 A:middle
on AutoCAD it's going
to look like this.

00:03:31.636 --> 00:03:32.746 A:middle
Like this.

00:03:34.016 --> 00:03:36.826 A:middle
So you're going to do
this in paper space,

00:03:37.606 --> 00:03:39.986 A:middle
 southeast isometric
for each of the parts

00:03:40.046 --> 00:03:42.256 A:middle
but when you're creating
the table you need

00:03:42.316 --> 00:03:46.426 A:middle
to change your UCS
to the current view

00:03:46.426 --> 00:03:49.406 A:middle
which is slant view,
which is the current view.

00:03:50.026 --> 00:03:54.696 A:middle
Otherwise it's going to
be on inclined plane.

00:03:55.946 --> 00:03:59.826 A:middle
So this constitutes part 3.

00:04:00.386 --> 00:04:02.236 A:middle
This is not necessary here.

00:04:02.576 --> 00:04:07.436 A:middle
If you want, you can simply
show that in part 4 of the lab.

00:04:08.736 --> 00:04:14.536 A:middle
So you're going to assemble
the different parts together.

00:04:15.216 --> 00:04:16.396 A:middle
It will look like this.

00:04:16.456 --> 00:04:19.416 A:middle
And I want you to -- with
the correct materials --

00:04:19.756 --> 00:04:24.166 A:middle
do a rendered version
like you've learned

00:04:24.166 --> 00:04:25.856 A:middle
in lab number 17 as well.

00:04:26.926 --> 00:04:30.666 A:middle
So for this lab -- since
this is a long lab --

00:04:30.666 --> 00:04:32.206 A:middle
you will have 2 weeks
to do this.

00:04:32.296 --> 00:04:36.516 A:middle
For the first part of the
week, you will do part 1.

00:04:36.986 --> 00:04:39.706 A:middle
And then parts 2,
3, and 4 will be

00:04:39.706 --> 00:04:41.856 A:middle
for the second part of the lab.
