00:00:00.476 --> 00:00:03.866 A:middle
>> This lecture is on the basic
functionality of SolidWorks.

00:00:04.376 --> 00:00:08.136 A:middle
We will be beginning with our
labs that deal with SolidWorks.

00:00:08.246 --> 00:00:09.976 A:middle
So, what is SolidWorks?

00:00:10.166 --> 00:00:14.566 A:middle
It's a design automation
software in SolidWorks,

00:00:14.566 --> 00:00:16.326 A:middle
you sketch ideas and experiment

00:00:16.326 --> 00:00:18.556 A:middle
with different designs
to create 3D models.

00:00:19.146 --> 00:00:20.886 A:middle
It's used by students,
designers,

00:00:20.886 --> 00:00:24.326 A:middle
and other professionals
to produce simple as well

00:00:24.326 --> 00:00:26.776 A:middle
as complex parts,
assemblies, or drawings.

00:00:26.866 --> 00:00:28.656 A:middle
Those are the three
types of files

00:00:28.726 --> 00:00:30.656 A:middle
that you can create
in SolidWorks.

00:00:31.086 --> 00:00:34.156 A:middle
Here's a look at the left
side of the SolidWorks window.

00:00:34.556 --> 00:00:37.556 A:middle
We have what is called
a feature design tree

00:00:37.556 --> 00:00:38.756 A:middle
when this is on here.

00:00:39.626 --> 00:00:43.346 A:middle
And then we have the property
manager when it's here.

00:00:43.666 --> 00:00:46.306 A:middle
So, this is context sensitive.

00:00:46.306 --> 00:00:50.936 A:middle
Or it depends on the context
of what you're currently doing.

00:00:51.406 --> 00:00:55.606 A:middle
This is configuration
manager when this is on.

00:00:56.056 --> 00:00:58.106 A:middle
On the right side of
the SolidWorks window,

00:00:58.106 --> 00:00:59.166 A:middle
we have the task pane.

00:00:59.606 --> 00:01:02.976 A:middle
That includes the SolidWorks
resources such as tutorials.

00:01:03.796 --> 00:01:07.206 A:middle
And we have the design
library still on the task pane.

00:01:07.206 --> 00:01:11.506 A:middle
Under the design library
we have the toolbox.

00:01:12.356 --> 00:01:16.156 A:middle
Commonly available parts
that have been pre-created

00:01:16.156 --> 00:01:19.886 A:middle
in SolidWorks, so you do
not have to create them.

00:01:19.886 --> 00:01:23.626 A:middle
And then we have the file
explorer also on the task bar.

00:01:24.076 --> 00:01:26.636 A:middle
Here are the tool
bars, which are buttons

00:01:26.636 --> 00:01:29.666 A:middle
for frequently used commands.

00:01:30.086 --> 00:01:32.706 A:middle
Initially, it looks very
different from AutoCAD,

00:01:32.706 --> 00:01:34.166 A:middle
and it is very different

00:01:34.226 --> 00:01:36.616 A:middle
but hopefully you will get
used to it pretty soon.

00:01:36.976 --> 00:01:39.026 A:middle
You can select the tool
bars that you display.

00:01:39.026 --> 00:01:40.056 A:middle
But my suggestion is

00:01:40.126 --> 00:01:43.756 A:middle
to initially just keep
the way the default is.

00:01:45.096 --> 00:01:48.836 A:middle
Tool bars are displayed at the
top and sides of the window.

00:01:48.836 --> 00:01:52.436 A:middle
And you can also access the tool
bars from the command manager.

00:01:53.026 --> 00:01:57.646 A:middle
If you are stuck and you need
help, you can get online help

00:01:57.646 --> 00:02:03.176 A:middle
by clicking on this icon here,
and it will open a help window.

00:02:03.776 --> 00:02:08.456 A:middle
And help displays in
a separate window.

00:02:08.656 --> 00:02:11.536 A:middle
There's three types of objects

00:02:11.536 --> 00:02:14.076 A:middle
that you can create
in SolidWorks.

00:02:14.076 --> 00:02:16.836 A:middle
The first one is this
symbol here, parts.

00:02:17.156 --> 00:02:19.316 A:middle
And then assemblies,
which is a collection

00:02:19.316 --> 00:02:20.716 A:middle
of two or more parts
and then drawings.

00:02:21.806 --> 00:02:23.216 A:middle
Here is an illustration.

00:02:23.286 --> 00:02:25.116 A:middle
A part is this one entity.

00:02:26.656 --> 00:02:29.426 A:middle
And you can have two
or more parts combined

00:02:29.486 --> 00:02:32.706 A:middle
to what's called and assembly.

00:02:32.706 --> 00:02:37.236 A:middle
And either from a part directly
you can create a drawing.

00:02:37.236 --> 00:02:41.146 A:middle
So, this is equivalent to
the paper space in AutoCAD

00:02:41.146 --> 00:02:43.856 A:middle
when we're doing our
Solview/Soldraw for instance.

00:02:44.596 --> 00:02:47.156 A:middle
And then you can
also create a drawing

00:02:47.156 --> 00:02:49.236 A:middle
out of an assembly
as illustrated here.

00:02:49.296 --> 00:02:50.786 A:middle
So, drawing can be
created directly

00:02:50.786 --> 00:02:53.416 A:middle
from a part or from an assembly.

00:02:54.686 --> 00:02:59.686 A:middle
The basis of creating
parts and assemblies

00:03:00.316 --> 00:03:03.666 A:middle
in SolidWorks are the features.

00:03:03.666 --> 00:03:06.806 A:middle
They are the building
blocks of a part.

00:03:07.196 --> 00:03:10.336 A:middle
And features are
shapes and operations

00:03:10.396 --> 00:03:11.676 A:middle
that construct the part.

00:03:11.676 --> 00:03:13.486 A:middle
So, unlock AutoCAD

00:03:13.486 --> 00:03:17.726 A:middle
where building blocks are
drawing entities like lines

00:03:17.726 --> 00:03:23.756 A:middle
or primitives, here they are
actually features that serve

00:03:23.756 --> 00:03:25.006 A:middle
as your building blocks.

00:03:25.006 --> 00:03:28.246 A:middle
So, the base feature
is the first feature

00:03:28.246 --> 00:03:29.666 A:middle
in the part that you create.

00:03:29.966 --> 00:03:34.486 A:middle
It is created from a 2D
sketch either by extrusion or revolving.

00:03:34.486 --> 00:03:38.726 A:middle
It forms the work piece to which
other features can be added

00:03:38.826 --> 00:03:41.796 A:middle
to such as the boss feature.

00:03:42.096 --> 00:03:45.556 A:middle
It's a feature that adds
material to the part.

00:03:45.556 --> 00:03:47.396 A:middle
So, this was the base
feature originally,

00:03:47.396 --> 00:03:50.906 A:middle
this rectangular
thin block here.

00:03:51.086 --> 00:03:54.236 A:middle
And then we have these two base
box features created initially

00:03:54.236 --> 00:03:57.436 A:middle
from a 2D sketch.

00:03:57.976 --> 00:04:01.566 A:middle
Another feature is the cut
feature, which removes material

00:04:01.566 --> 00:04:03.096 A:middle
from the part, which is, again,

00:04:03.096 --> 00:04:05.466 A:middle
created from initially
from a 2D sketch.

00:04:06.146 --> 00:04:09.066 A:middle
The hole feature also
removes materials.

00:04:09.066 --> 00:04:12.426 A:middle
It works like an intelligent
cut feature and corresponds

00:04:12.496 --> 00:04:16.586 A:middle
to drilling processes such as
creating counter-sink thread

00:04:17.706 --> 00:04:21.996 A:middle
and counter-bore We
have it illustrated here

00:04:21.996 --> 00:04:23.296 A:middle
from this to this.

00:04:23.296 --> 00:04:26.816 A:middle
We have the fillet
feature, which is used

00:04:26.846 --> 00:04:30.816 A:middle
to round off sharp edges and
can remove or add materials.

00:04:30.816 --> 00:04:32.236 A:middle
In this case, it was removed.

00:04:32.836 --> 00:04:33.856 A:middle
But it can also add.

00:04:34.156 --> 00:04:36.426 A:middle
And rounding of sharp edges.

00:04:36.566 --> 00:04:42.226 A:middle
If it's outside, it's an outside
edge, it removes some material.

00:04:42.616 --> 00:04:43.936 A:middle
It creates a convex fillet.

00:04:43.936 --> 00:04:48.156 A:middle
If it's an inside
edge, it adds material

00:04:48.156 --> 00:04:49.816 A:middle
to create a concave fillet.

00:04:50.706 --> 00:04:55.706 A:middle
Similar to the fillet
is the chamfer feature.

00:04:56.816 --> 00:04:58.226 A:middle
Instead of rounding off,

00:04:58.226 --> 00:05:00.766 A:middle
it bevels an edge
rather than rounding.

00:05:00.766 --> 00:05:02.846 A:middle
Here is an example
of the chamfer.

00:05:03.396 --> 00:05:08.276 A:middle
And it can also either remove
or add material to your part.

00:05:09.166 --> 00:05:11.596 A:middle
Sketched features are
features that start

00:05:11.996 --> 00:05:15.636 A:middle
from sketches and have 
sketches associated with them.

00:05:15.636 --> 00:05:18.016 A:middle
Sketched features are
build from 2D profiles.

00:05:18.836 --> 00:05:21.926 A:middle
On the other hand, operation
features are features

00:05:21.926 --> 00:05:24.306 A:middle
that do not have sketches
and are applied directly

00:05:24.306 --> 00:05:27.856 A:middle
to the work piece by
selecting edges or faces.

00:05:29.626 --> 00:05:30.626 A:middle
Here's an illustration

00:05:30.626 --> 00:05:33.726 A:middle
of creating a base
feature by extrusion.

00:05:33.936 --> 00:05:36.216 A:middle
So, you start by
selecting a sketch plane.

00:05:36.216 --> 00:05:39.436 A:middle
In this case, we select
a front right here.

00:05:40.016 --> 00:05:43.696 A:middle
And then on the front view,
you select a 2D profile

00:05:43.696 --> 00:05:45.766 A:middle
such as this rectangle
for instance.

00:05:45.766 --> 00:05:50.086 A:middle
And then you extrude the sketch
perpendicular to the plane

00:05:50.086 --> 00:05:53.006 A:middle
to create your rectangular
base feature.

00:05:54.366 --> 00:05:56.776 A:middle
You can also create
this base feature

00:05:56.776 --> 00:05:58.176 A:middle
from the revolve command.

00:05:58.696 --> 00:06:00.466 A:middle
You start with a
sketch plane again.

00:06:00.826 --> 00:06:03.736 A:middle
And you sketch the 2D profile
if you want to revolve.

00:06:03.936 --> 00:06:08.586 A:middle
It's very similar to one
of your labs in AutoCAD.

00:06:09.076 --> 00:06:11.266 A:middle
And then you sketch
a center line.

00:06:11.386 --> 00:06:17.096 A:middle
This is optional because you
can either revolve 2D profile

00:06:17.096 --> 00:06:20.636 A:middle
of your sketch around either
sketch line or a center line

00:06:20.676 --> 00:06:24.296 A:middle
to give you your
revolve base feature.

00:06:24.816 --> 00:06:29.626 A:middle
Some more terminology
in SolidWorks.

00:06:30.006 --> 00:06:32.836 A:middle
The document window is
divided into two panels.

00:06:32.916 --> 00:06:36.366 A:middle
The left side here is just a
Feature Manager design tree.

00:06:36.366 --> 00:06:37.936 A:middle
We've seen that earlier.

00:06:37.936 --> 00:06:41.076 A:middle
And this main area here
is the graphics area.

00:06:41.986 --> 00:06:45.166 A:middle
So, the left panel contains the
Feature Manager design tree.

00:06:45.166 --> 00:06:48.146 A:middle
It lists the structure of the
part, assembly, and drawing,

00:06:48.326 --> 00:06:49.536 A:middle
the different features in it.

00:06:50.726 --> 00:06:52.886 A:middle
And the right panel
contains the graphics area.

00:06:53.156 --> 00:06:56.096 A:middle
It's the location
to display, create,

00:06:56.096 --> 00:06:58.876 A:middle
and modify a part,
assembly, or drawing.

00:06:59.286 --> 00:07:00.966 A:middle
So, here's an illustration

00:07:00.966 --> 00:07:04.956 A:middle
of the different parts
of the SolidWorks.

00:07:05.676 --> 00:07:08.236 A:middle
Here's the menu bar,
the tool bars,

00:07:08.236 --> 00:07:10.416 A:middle
the command manager
is right here.

00:07:11.266 --> 00:07:14.126 A:middle
This is the part
document window.

00:07:14.726 --> 00:07:16.276 A:middle
And here is your
drawing document.

00:07:16.716 --> 00:07:20.076 A:middle
This is a status bar
down here and a task pane

00:07:20.076 --> 00:07:22.916 A:middle
that contains among other things
your resources

00:07:23.166 --> 00:07:25.506 A:middle
and your design library.

00:07:26.756 --> 00:07:28.996 A:middle
So, this is a property,
illustration

00:07:28.996 --> 00:07:30.266 A:middle
of the property manager.

00:07:31.746 --> 00:07:34.646 A:middle
Depending on what command
you're using, different types

00:07:34.646 --> 00:07:37.986 A:middle
of properties will be displayed
here for the property manager.

00:07:37.986 --> 00:07:43.346 A:middle
And there's the confirmation
corner to either OK

00:07:43.696 --> 00:07:47.236 A:middle
or accept or delete or cancel.

00:07:48.266 --> 00:07:50.726 A:middle
Other terminologies.

00:07:50.726 --> 00:07:51.886 A:middle
Basic geometry.

00:07:52.736 --> 00:07:55.756 A:middle
Axis is an implied
center line that runs

00:07:55.756 --> 00:07:58.366 A:middle
through every cylindrical
feature right here.

00:07:59.046 --> 00:08:01.656 A:middle
That's the center
line of the cylinder.

00:08:02.196 --> 00:08:05.206 A:middle
Plane is a flat 2D surface.

00:08:05.466 --> 00:08:05.916 A:middle
We know that.

00:08:06.266 --> 00:08:08.536 A:middle
It can have multiple
planes of construction

00:08:08.536 --> 00:08:09.636 A:middle
as we will see later on.

00:08:10.126 --> 00:08:13.316 A:middle
Origin is where your x,
y, and z are all zero.

00:08:13.686 --> 00:08:16.936 A:middle
It is used for locating
coordinates of points.

00:08:17.856 --> 00:08:19.236 A:middle
More terminology.

00:08:19.236 --> 00:08:21.166 A:middle
We have something called a face.

00:08:22.316 --> 00:08:23.406 A:middle
We learned this before too.

00:08:23.776 --> 00:08:27.986 A:middle
Face is the surface
or skin of a part.

00:08:28.386 --> 00:08:29.876 A:middle
Faces can be flat or curved.

00:08:29.876 --> 00:08:32.136 A:middle
Here is examples of faces here.

00:08:32.786 --> 00:08:34.336 A:middle
This face here that's vertical.

00:08:34.336 --> 00:08:35.266 A:middle
The one horizontal.

00:08:35.266 --> 00:08:39.126 A:middle
The cylindrical surface
also here is a face.

00:08:39.936 --> 00:08:43.026 A:middle
We have edge, which is
intersection between two faces

00:08:43.026 --> 00:08:46.786 A:middle
or the boundary of a face.

00:08:46.786 --> 00:08:50.816 A:middle
And edges it says here can be
straight like these ones up here

00:08:50.846 --> 00:08:53.676 A:middle
or curved corresponding
to this circle

00:08:54.106 --> 00:08:55.886 A:middle
that defines the cylinder.

00:08:57.016 --> 00:09:00.216 A:middle
Vertex is the intersection
of edges.

00:09:00.396 --> 00:09:01.406 A:middle
So, here is one vertex.

00:09:01.726 --> 00:09:03.006 A:middle
Those are other vertices.

00:09:04.366 --> 00:09:06.256 A:middle
More, base feature.

00:09:06.736 --> 00:09:08.366 A:middle
As we said earlier,
it's the first base,

00:09:09.186 --> 00:09:11.226 A:middle
the first feature
that is created.

00:09:11.226 --> 00:09:13.646 A:middle
It is the foundation
of the part.

00:09:13.776 --> 00:09:16.536 A:middle
You can add and subtract
materials to the base feature.

00:09:16.976 --> 00:09:19.546 A:middle
The base feature geometry
for the box is an extrusion.

00:09:19.546 --> 00:09:24.506 A:middle
So, you start with a rectangle
sketch, and then you extrude it.

00:09:25.426 --> 00:09:27.196 A:middle
It's called Extrude1.

00:09:27.276 --> 00:09:31.736 A:middle
If your base feature is a
revolve feature it will be

00:09:31.736 --> 00:09:32.586 A:middle
called Revolve1.

00:09:34.256 --> 00:09:38.306 A:middle
Features to build the box,
so this is an illustration

00:09:38.306 --> 00:09:39.946 A:middle
of the first lab
that you will do.

00:09:39.946 --> 00:09:44.286 A:middle
You are going to start with an
extruded base feature starting

00:09:44.286 --> 00:09:46.296 A:middle
from a sketch in the
front and then extrude it

00:09:46.356 --> 00:09:47.966 A:middle
to give you base feature.

00:09:47.966 --> 00:09:53.026 A:middle
And then you fillet to
create the fillet feature.

00:09:54.056 --> 00:09:57.506 A:middle
The four vertical
edges of the box.

00:09:57.506 --> 00:10:02.976 A:middle
Then we'll had a shell feature
by removing this middle part.

00:10:03.096 --> 00:10:08.526 A:middle
And then extruded cut feature
to add those two holes.

00:10:09.716 --> 00:10:12.646 A:middle
So, here's an illustration
of the steps.

00:10:12.646 --> 00:10:16.326 A:middle
You create the extruded
base feature for the box

00:10:16.326 --> 00:10:23.266 A:middle
by first starting with a sketch
plane and creating a rectangle

00:10:23.266 --> 00:10:26.466 A:middle
on that sketch plane and
extruding the sketch.

00:10:28.026 --> 00:10:29.526 A:middle
By default, the direction

00:10:29.526 --> 00:10:32.006 A:middle
of exclusion is perpendicular
to the sketch plane.

00:10:32.246 --> 00:10:37.586 A:middle
Then we had the fillet
feature by selecting select

00:10:38.256 --> 00:10:41.306 A:middle
and then selecting the
edges to be selected.

00:10:41.736 --> 00:10:44.306 A:middle
Specify the fillet
radius of course.

00:10:44.856 --> 00:10:46.806 A:middle
And that rounds out
those sharp corners.

00:10:47.316 --> 00:10:51.456 A:middle
Then we do the shell feature
by selecting the top face.

00:10:51.646 --> 00:10:52.996 A:middle
It removes the material.

00:10:54.486 --> 00:10:57.096 A:middle
It creates a hollow
box from the solid box.

00:10:58.056 --> 00:10:59.766 A:middle
And we can specify the thickness

00:10:59.796 --> 00:11:03.236 A:middle
of the wall in the
shell feature.

00:11:04.236 --> 00:11:08.856 A:middle
Then we do the cut
feature, which we start

00:11:08.936 --> 00:11:12.866 A:middle
with a 2D circular
profile on one plane here.

00:11:13.356 --> 00:11:16.686 A:middle
And then it's extruded
perpendicular

00:11:16.686 --> 00:11:17.716 A:middle
to the sketch plane.

00:11:17.986 --> 00:11:20.016 A:middle
And we enter through all,
through all means that

00:11:20.016 --> 00:11:24.666 A:middle
the hole is going to extend all
throughout the entire part

00:11:25.996 --> 00:11:28.256 A:middle
perpendicular to
the sketch circle.

00:11:28.826 --> 00:11:34.316 A:middle
And the circle cut penetrates
through the entire part.

00:11:34.806 --> 00:11:35.906 A:middle
More definitions.

00:11:36.796 --> 00:11:39.576 A:middle
We can specify dimensions
and geometric relationships

00:11:39.576 --> 00:11:41.006 A:middle
between features and sketches.

00:11:41.546 --> 00:11:44.116 A:middle
Dimensions change the size
and shape of the part.

00:11:44.536 --> 00:11:46.526 A:middle
And we can also have
mathematical relationships

00:11:46.526 --> 00:11:48.656 A:middle
between dimensions in order

00:11:48.726 --> 00:11:53.356 A:middle
to control the properties
of our part.

00:11:53.356 --> 00:11:56.416 A:middle
Geometrical relationships are
rules that control the behavior

00:11:56.416 --> 00:12:00.216 A:middle
of sketch geometry meaning
geometric relationships

00:12:00.346 --> 00:12:06.416 A:middle
between different
features in our part.

00:12:06.886 --> 00:12:10.016 A:middle
Geometric relationships
help create design intent.

00:12:10.126 --> 00:12:13.056 A:middle
So, here are two
dimensions shown here.

00:12:13.366 --> 00:12:17.186 A:middle
The base depth here is
50 and in this example,

00:12:17.266 --> 00:12:19.316 A:middle
the boss is the feature added

00:12:19.316 --> 00:12:22.766 A:middle
on to the base feature
is 25 millimeters.

00:12:22.976 --> 00:12:25.096 A:middle
And we can have a
mathematical relationship.

00:12:25.166 --> 00:12:29.656 A:middle
We can say, for instance,
that if I change this part,

00:12:30.466 --> 00:12:32.786 A:middle
I want this mathematical
relationship

00:12:32.786 --> 00:12:36.386 A:middle
such that the boss
depth is always equal

00:12:36.386 --> 00:12:38.026 A:middle
to the base depth
divided by two.

00:12:38.096 --> 00:12:40.246 A:middle
If I change the base
depth to 100,

00:12:40.566 --> 00:12:44.056 A:middle
automatically the boss
depth will be half of that.

00:12:44.536 --> 00:12:47.896 A:middle
Other geometric relationships
such as tangent.

00:12:48.046 --> 00:12:53.986 A:middle
Tangency between an arc and a
line, two circles or two arcs.

00:12:55.546 --> 00:12:59.026 A:middle
Geometric relationship
called vertical, horizontal,

00:12:59.136 --> 00:13:03.106 A:middle
intersections of two entities or
lines, lines that are parallel,

00:13:03.176 --> 00:13:05.716 A:middle
concentric circles, and
perpendicular very similar

00:13:05.716 --> 00:13:09.976 A:middle
to the object snaps in AutoCAD.

00:13:11.176 --> 00:13:15.156 A:middle
Now, to start SolidWorks you
can either just double click

00:13:15.156 --> 00:13:18.786 A:middle
on the icon on your desktop or
you can use the start button

00:13:18.996 --> 00:13:24.376 A:middle
in your task bar and click
programs and look for SolidWorks

00:13:24.376 --> 00:13:26.426 A:middle
and it will open the
SolidWorks window.

00:13:27.266 --> 00:13:30.196 A:middle
Then we'll ask you what
you are trying to create.

00:13:30.396 --> 00:13:33.736 A:middle
You can start with a part.

00:13:33.906 --> 00:13:39.196 A:middle
Hit new. Select the new
in the standard toolbar

00:13:39.196 --> 00:13:44.026 A:middle
and say you want
to create a part.

00:13:44.026 --> 00:13:48.506 A:middle
You can also document
properties if you want

00:13:48.976 --> 00:13:51.386 A:middle
which can be accessed through
the tools, options menu.

00:13:52.676 --> 00:13:56.096 A:middle
And you can control settings
like the units, the grid

00:13:56.096 --> 00:13:59.056 A:middle
and snap settings, colors,
material properties,

00:13:59.056 --> 00:14:02.056 A:middle
and image quality for instance.

00:14:03.486 --> 00:14:06.136 A:middle
The system options
can be accessed

00:14:06.136 --> 00:14:07.936 A:middle
through the tools,
options menu as well.

00:14:08.076 --> 00:14:11.296 A:middle
It allows you to customize
your work and environment

00:14:13.056 --> 00:14:16.656 A:middle
such as file locations,
performance, and etcetera.

00:14:16.976 --> 00:14:18.676 A:middle
So, you can also,
just like AutoCAD,

00:14:19.106 --> 00:14:21.446 A:middle
display multiple views
of the same part.

00:14:22.706 --> 00:14:24.906 A:middle
You can do single,
two-view, or four-view.

00:14:26.086 --> 00:14:29.646 A:middle
Here is the sketch tool bar.

00:14:30.546 --> 00:14:33.546 A:middle
When you do that, it asks
you for a sketch plane.

00:14:33.966 --> 00:14:36.626 A:middle
And then if you click on
a rectangle, for instance,

00:14:36.626 --> 00:14:44.506 A:middle
to create the sketch and
move the origin to serve

00:14:44.506 --> 00:14:48.286 A:middle
as the starting point of
your rectangular sketch.

00:14:48.426 --> 00:14:49.286 A:middle
Here's an illustration.

00:14:50.346 --> 00:14:54.176 A:middle
And left mouse button, drag
to the upper, up to the right,

00:14:54.866 --> 00:14:56.656 A:middle
upper right corner
of the rectangle.

00:14:56.656 --> 00:14:57.976 A:middle
And that should be it.

00:14:58.356 --> 00:15:01.076 A:middle
Now, the good thing about
AutoCAD is when you, no,

00:15:01.416 --> 00:15:04.076 A:middle
SolidWorks is that when you're
initially making the sketches,

00:15:04.936 --> 00:15:08.116 A:middle
you don't have to be exact
because you can change

00:15:08.116 --> 00:15:12.576 A:middle
and specify dimensions
using what is called the

00:15:12.576 --> 00:15:13.526 A:middle
smart dimension.

00:15:15.286 --> 00:15:18.546 A:middle
So, for instance, if you
initially created a rectangle

00:15:18.546 --> 00:15:24.766 A:middle
of some arbitrary dimensions
of 110.61 and 96.40,

00:15:25.266 --> 00:15:28.906 A:middle
don't worry about it because
you can adjust those dimensions

00:15:28.906 --> 00:15:32.426 A:middle
using the Smart Dimension.

00:15:32.736 --> 00:15:36.176 A:middle
Click on the geometry and
click on the text location

00:15:36.266 --> 00:15:39.086 A:middle
and enter the value
that you want.

00:15:39.086 --> 00:15:43.956 A:middle
So, you can change the 110 and
the 96.4 to whatever you want,

00:15:43.956 --> 00:15:46.396 A:middle
say 100, without
redoing this sketching.

00:15:46.396 --> 00:15:51.746 A:middle
And you can change, you can use
the Smart Dimensions anytime

00:15:51.746 --> 00:15:54.536 A:middle
throughout the creation
of the part.

00:15:55.206 --> 00:15:58.826 A:middle
For your lab, the second part
of your lab, you're going

00:15:58.826 --> 00:16:02.326 A:middle
to create, follow a
tutorial on SolidWorks.

00:16:03.666 --> 00:16:05.236 A:middle
And here's an illustration

00:16:05.396 --> 00:16:08.826 A:middle
of the part called
Tutor1 will be created.

00:16:08.826 --> 00:16:11.526 A:middle
You can start with a
base extrude and then

00:16:11.716 --> 00:16:13.396 A:middle
with a cylindrical boss extrude.

00:16:13.606 --> 00:16:14.596 A:middle
And then the cut feature.

00:16:14.596 --> 00:16:19.826 A:middle
And then the fillet feature
to round off some edges.

00:16:19.826 --> 00:16:21.016 A:middle
And then the shell feature.

00:16:21.016 --> 00:16:23.716 A:middle
And that will be your Tutor1.

00:16:23.716 --> 00:16:27.906 A:middle
The Tutor1 file will be
used for your next lab.

00:16:28.676 --> 00:16:32.366 A:middle
So, for the extrude boss
feature, you add material

00:16:32.366 --> 00:16:33.906 A:middle
to the part as we said.

00:16:33.906 --> 00:16:35.256 A:middle
And it requires a sketch.

00:16:35.716 --> 00:16:42.316 A:middle
For the extruded cut feature, it
removes material from the part

00:16:42.316 --> 00:16:43.746 A:middle
and also requires a sketch.

00:16:43.866 --> 00:16:46.246 A:middle
For the fillet feature,
you don't need a sketch.

00:16:46.886 --> 00:16:53.206 A:middle
Just round edges of a part
using a specified radius.

00:16:54.136 --> 00:16:57.286 A:middle
The shell feature
removes materials.

00:16:58.246 --> 00:17:00.216 A:middle
Very useful for thin-walled
plastic parts.

00:17:00.646 --> 00:17:02.796 A:middle
You are required to
specify wall thickness

00:17:02.796 --> 00:17:05.716 A:middle
when you are using
the shell feature.

00:17:06.406 --> 00:17:09.526 A:middle
Some important tools.

00:17:09.996 --> 00:17:11.286 A:middle
The view control.

00:17:12.356 --> 00:17:16.136 A:middle
You can manipulate
the view of the part

00:17:16.626 --> 00:17:18.476 A:middle
that you are seeing while
you are creating it.

00:17:18.546 --> 00:17:21.796 A:middle
You can do zoom to fit, zoom
to area, zoom in and out,

00:17:22.296 --> 00:17:23.516 A:middle
and so on and so forth.

00:17:23.886 --> 00:17:26.006 A:middle
The display modes
can also be changed.

00:17:28.266 --> 00:17:29.516 A:middle
These are illustrations.

00:17:29.516 --> 00:17:31.366 A:middle
You can do wire frame.

00:17:31.516 --> 00:17:36.716 A:middle
There's some similarities here
with visual settings in AutoCAD.

00:17:36.786 --> 00:17:38.816 A:middle
You can do hidden
lines, hidden lines,

00:17:38.816 --> 00:17:41.286 A:middle
removed, shaded, and so on.

00:17:42.216 --> 00:17:43.676 A:middle
There are also different views.

00:17:45.606 --> 00:17:49.646 A:middle
Your isometric, trimetric,
top, back, left,

00:17:49.646 --> 00:17:50.696 A:middle
and so on and so forth.

00:17:51.436 --> 00:17:53.636 A:middle
And they're all found
here in this icon.

00:17:53.636 --> 00:17:55.966 A:middle
So, here is the front,
right, and bottom, isometric.

00:17:57.316 --> 00:18:02.756 A:middle
Normal means normal to the
selected plane or plane face.

00:18:03.796 --> 00:18:06.206 A:middle
Here's illustrations
of those views.

00:18:06.976 --> 00:18:10.706 A:middle
View orientation
also as shown here.

00:18:12.546 --> 00:18:15.796 A:middle
Top, front, right,
isometric, and trimetric.

00:18:15.956 --> 00:18:19.946 A:middle
Trimetric, the isometric is
one in which the angle here

00:18:19.946 --> 00:18:24.426 A:middle
of this edge, of the"z" in this
case  30 degrees with the horizontal

00:18:24.426 --> 00:18:28.806 A:middle
and the X is also 30 degrees
introspect to the horizontal.

00:18:29.396 --> 00:18:33.066 A:middle
But sometimes it is difficult
to visualize the object

00:18:33.066 --> 00:18:35.366 A:middle
by looking at it in isometric.

00:18:35.436 --> 00:18:38.256 A:middle
So, in fact, trimetric
because it's not symmetric,

00:18:40.086 --> 00:18:44.516 A:middle
is usually easier to
use and visualize.

00:18:45.576 --> 00:18:51.866 A:middle
Default planes, front, top,
and right, which we had before.

00:18:51.966 --> 00:18:53.386 A:middle
And so on.

00:18:53.386 --> 00:18:57.236 A:middle
The isometric view displays
the part with height, width,

00:18:57.546 --> 00:19:01.846 A:middle
equally foreshortened and this
angle here as I indicated was 30

00:19:01.846 --> 00:19:04.506 A:middle
and 30, and the Y is vertical.

00:19:05.146 --> 00:19:09.346 A:middle
You can also view
the section view

00:19:09.346 --> 00:19:12.046 A:middle
by simply creating the
location of your cutting plane.

00:19:13.936 --> 00:19:15.126 A:middle
Very, very important.

00:19:15.406 --> 00:19:17.446 A:middle
When you're doing sketches, OK,

00:19:17.446 --> 00:19:19.546 A:middle
there's three different
conditions

00:19:19.916 --> 00:19:23.156 A:middle
that your sketch can fall under.

00:19:23.666 --> 00:19:24.716 A:middle
One is something called

00:19:24.716 --> 00:19:28.536 A:middle
under defined meaning
additional dimensions

00:19:28.536 --> 00:19:29.816 A:middle
or relations are required.

00:19:29.816 --> 00:19:34.236 A:middle
So, that particular sketch
is not completely defined.

00:19:34.236 --> 00:19:36.456 A:middle
And you know that it
is completely defined

00:19:36.456 --> 00:19:40.596 A:middle
or under defined because
it is shown in blue.

00:19:40.886 --> 00:19:43.766 A:middle
So, when these sides are
blue, that means the length

00:19:43.846 --> 00:19:46.926 A:middle
of this side and this side
are not completely defined.

00:19:47.426 --> 00:19:50.486 A:middle
When something is fully defined,
there's no additional dimensions

00:19:50.486 --> 00:19:53.756 A:middle
or relationships required
to fully define the sketch.

00:19:53.756 --> 00:19:58.636 A:middle
So, for instance when I say
this is 40 and this is 80.

00:19:59.746 --> 00:20:02.636 A:middle
This becomes completely defined,
and the lines turn black.

00:20:03.306 --> 00:20:06.366 A:middle
On the other hand, sometimes
you may have something that's

00:20:06.366 --> 00:20:11.586 A:middle
over defined, meaning it
contains conflicting information

00:20:12.266 --> 00:20:15.436 A:middle
either in dimensions,
relations, or both.

00:20:15.436 --> 00:20:17.626 A:middle
And when something is
over defined you will know

00:20:17.626 --> 00:20:21.126 A:middle
because the computer
will complain.

00:20:21.316 --> 00:20:23.736 A:middle
It will show those
entities as red.

00:20:23.736 --> 00:20:24.796 A:middle
Here's an example here.
