>> This lecture is on the basic functionality of SolidWorks.
We will be beginning with our labs that deal with SolidWorks.
So, what is SolidWorks?
It's a design automation software in SolidWorks,
you sketch ideas and experiment
with different designs to create 3D models.
It's used by students, designers,
and other professionals to produce simple as well
as complex parts, assemblies, or drawings.
Those are the three types of files
that you can create in SolidWorks.
Here's a look at the left side of the SolidWorks window.
We have what is called a feature design tree
when this is on here.
And then we have the property manager when it's here.
So, this is context sensitive.
Or it depends on the context of what you're currently doing.
This is configuration manager when this is on.
On the right side of the SolidWorks window,
we have the task pane.
That includes the SolidWorks resources such as tutorials.
And we have the design library still on the task pane.
Under the design library we have the toolbox.
Commonly available parts that have been pre-created
in SolidWorks, so you do not have to create them.
And then we have the file explorer also on the task bar.
Here are the tool bars, which are buttons
for frequently used commands.
Initially, it looks very different from AutoCAD,
and it is very different
but hopefully you will get used to it pretty soon.
You can select the tool bars that you display.
But my suggestion is
to initially just keep the way the default is.
Tool bars are displayed at the top and sides of the window.
And you can also access the tool bars from the command manager.
If you are stuck and you need help, you can get online help
by clicking on this icon here, and it will open a help window.
And help displays in a separate window.
There's three types of objects
that you can create in SolidWorks.
The first one is this symbol here, parts.
And then assemblies, which is a collection
of two or more parts and then drawings.
Here is an illustration.
A part is this one entity.
And you can have two or more parts combined
to what's called and assembly.
And either from a part directly you can create a drawing.
So, this is equivalent to the paper space in AutoCAD
when we're doing our Solview/Soldraw for instance.
And then you can also create a drawing
out of an assembly as illustrated here.
So, drawing can be created directly
from a part or from an assembly.
The basis of creating parts and assemblies
in SolidWorks are the features.
They are the building blocks of a part.
And features are shapes and operations
that construct the part.
So, unlock AutoCAD
where building blocks are drawing entities like lines
or primitives, here they are actually features that serve
as your building blocks.
So, the base feature is the first feature
in the part that you create.
It is created from a 2D sketch either by extrusion or revolving.
It forms the work piece to which other features can be added
to such as the boss feature.
It's a feature that adds material to the part.
So, this was the base feature originally,
this rectangular thin block here.
And then we have these two base box features created initially
from a 2D sketch.
Another feature is the cut feature, which removes material
from the part, which is, again,
created from initially from a 2D sketch.
The hole feature also removes materials.
It works like an intelligent cut feature and corresponds
to drilling processes such as creating counter-sink thread
and counter-bore We have it illustrated here
from this to this.
We have the fillet feature, which is used
to round off sharp edges and can remove or add materials.
In this case, it was removed.
But it can also add.
And rounding of sharp edges.
If it's outside, it's an outside edge, it removes some material.
It creates a convex fillet.
If it's an inside edge, it adds material
to create a concave fillet.
Similar to the fillet is the chamfer feature.
Instead of rounding off,
it bevels an edge rather than rounding.
Here is an example of the chamfer.
And it can also either remove or add material to your part.
Sketched features are features that start
from sketches and have sketches associated with them.
Sketched features are build from 2D profiles.
On the other hand, operation features are features
that do not have sketches and are applied directly
to the work piece by selecting edges or faces.
Here's an illustration
of creating a base feature by extrusion.
So, you start by selecting a sketch plane.
In this case, we select a front right here.
And then on the front view, you select a 2D profile
such as this rectangle for instance.
And then you extrude the sketch perpendicular to the plane
to create your rectangular base feature.
You can also create this base feature
from the revolve command.
You start with a sketch plane again.
And you sketch the 2D profile if you want to revolve.
It's very similar to one of your labs in AutoCAD.
And then you sketch a center line.
This is optional because you can either revolve 2D profile
of your sketch around either sketch line or a center line
to give you your revolve base feature.
Some more terminology in SolidWorks.
The document window is divided into two panels.
The left side here is just a Feature Manager design tree.
We've seen that earlier.
And this main area here is the graphics area.
So, the left panel contains the Feature Manager design tree.
It lists the structure of the part, assembly, and drawing,
the different features in it.
And the right panel contains the graphics area.
It's the location to display, create,
and modify a part, assembly, or drawing.
So, here's an illustration
of the different parts of the SolidWorks.
Here's the menu bar, the tool bars,
the command manager is right here.
This is the part document window.
And here is your drawing document.
This is a status bar down here and a task pane
that contains among other things your resources
and your design library.
So, this is a property, illustration
of the property manager.
Depending on what command you're using, different types
of properties will be displayed here for the property manager.
And there's the confirmation corner to either OK
or accept or delete or cancel.
Other terminologies.
Basic geometry.
Axis is an implied center line that runs
through every cylindrical feature right here.
That's the center line of the cylinder.
Plane is a flat 2D surface.
We know that.
It can have multiple planes of construction
as we will see later on.
Origin is where your x, y, and z are all zero.
It is used for locating coordinates of points.
More terminology.
We have something called a face.
We learned this before too.
Face is the surface or skin of a part.
Faces can be flat or curved.
Here is examples of faces here.
This face here that's vertical.
The one horizontal.
The cylindrical surface also here is a face.
We have edge, which is intersection between two faces
or the boundary of a face.
And edges it says here can be straight like these ones up here
or curved corresponding to this circle
that defines the cylinder.
Vertex is the intersection of edges.
So, here is one vertex.
Those are other vertices.
More, base feature.
As we said earlier, it's the first base,
the first feature that is created.
It is the foundation of the part.
You can add and subtract materials to the base feature.
The base feature geometry for the box is an extrusion.
So, you start with a rectangle sketch, and then you extrude it.
It's called Extrude1.
If your base feature is a revolve feature it will be
called Revolve1.
Features to build the box, so this is an illustration
of the first lab that you will do.
You are going to start with an extruded base feature starting
from a sketch in the front and then extrude it
to give you base feature.
And then you fillet to create the fillet feature.
The four vertical edges of the box.
Then we'll had a shell feature by removing this middle part.
And then extruded cut feature to add those two holes.
So, here's an illustration of the steps.
You create the extruded base feature for the box
by first starting with a sketch plane and creating a rectangle
on that sketch plane and extruding the sketch.
By default, the direction
of exclusion is perpendicular to the sketch plane.
Then we had the fillet feature by selecting select
and then selecting the edges to be selected.
Specify the fillet radius of course.
And that rounds out those sharp corners.
Then we do the shell feature by selecting the top face.
It removes the material.
It creates a hollow box from the solid box.
And we can specify the thickness
of the wall in the shell feature.
Then we do the cut feature, which we start
with a 2D circular profile on one plane here.
And then it's extruded perpendicular
to the sketch plane.
And we enter through all, through all means that
the hole is going to extend all throughout the entire part
perpendicular to the sketch circle.
And the circle cut penetrates through the entire part.
More definitions.
We can specify dimensions and geometric relationships
between features and sketches.
Dimensions change the size and shape of the part.
And we can also have mathematical relationships
between dimensions in order
to control the properties of our part.
Geometrical relationships are rules that control the behavior
of sketch geometry meaning geometric relationships
between different features in our part.
Geometric relationships help create design intent.
So, here are two dimensions shown here.
The base depth here is 50 and in this example,
the boss is the feature added
on to the base feature is 25 millimeters.
And we can have a mathematical relationship.
We can say, for instance, that if I change this part,
I want this mathematical relationship
such that the boss depth is always equal
to the base depth divided by two.
If I change the base depth to 100,
automatically the boss depth will be half of that.
Other geometric relationships such as tangent.
Tangency between an arc and a line, two circles or two arcs.
Geometric relationship called vertical, horizontal,
intersections of two entities or lines, lines that are parallel,
concentric circles, and perpendicular very similar
to the object snaps in AutoCAD.
Now, to start SolidWorks you can either just double click
on the icon on your desktop or you can use the start button
in your task bar and click programs and look for SolidWorks
and it will open the SolidWorks window.
Then we'll ask you what you are trying to create.
You can start with a part.
Hit new. Select the new in the standard toolbar
and say you want to create a part.
You can also document properties if you want
which can be accessed through the tools, options menu.
And you can control settings like the units, the grid
and snap settings, colors, material properties,
and image quality for instance.
The system options can be accessed
through the tools, options menu as well.
It allows you to customize your work and environment
such as file locations, performance, and etcetera.
So, you can also, just like AutoCAD,
display multiple views of the same part.
You can do single, two-view, or four-view.
Here is the sketch tool bar.
When you do that, it asks you for a sketch plane.
And then if you click on a rectangle, for instance,
to create the sketch and move the origin to serve
as the starting point of your rectangular sketch.
Here's an illustration.
And left mouse button, drag to the upper, up to the right,
upper right corner of the rectangle.
And that should be it.
Now, the good thing about AutoCAD is when you, no,
SolidWorks is that when you're initially making the sketches,
you don't have to be exact because you can change
and specify dimensions using what is called the
smart dimension.
So, for instance, if you initially created a rectangle
of some arbitrary dimensions of 110.61 and 96.40,
don't worry about it because you can adjust those dimensions
using the Smart Dimension.
Click on the geometry and click on the text location
and enter the value that you want.
So, you can change the 110 and the 96.4 to whatever you want,
say 100, without redoing this sketching.
And you can change, you can use the Smart Dimensions anytime
throughout the creation of the part.
For your lab, the second part of your lab, you're going
to create, follow a tutorial on SolidWorks.
And here's an illustration
of the part called Tutor1 will be created.
You can start with a base extrude and then
with a cylindrical boss extrude.
And then the cut feature.
And then the fillet feature to round off some edges.
And then the shell feature.
And that will be your Tutor1.
The Tutor1 file will be used for your next lab.
So, for the extrude boss feature, you add material
to the part as we said.
And it requires a sketch.
For the extruded cut feature, it removes material from the part
and also requires a sketch.
For the fillet feature, you don't need a sketch.
Just round edges of a part using a specified radius.
The shell feature removes materials.
Very useful for thin-walled plastic parts.
You are required to specify wall thickness
when you are using the shell feature.
Some important tools.
The view control.
You can manipulate the view of the part
that you are seeing while you are creating it.
You can do zoom to fit, zoom to area, zoom in and out,
and so on and so forth.
The display modes can also be changed.
These are illustrations.
You can do wire frame.
There's some similarities here with visual settings in AutoCAD.
You can do hidden lines, hidden lines,
removed, shaded, and so on.
There are also different views.
Your isometric, trimetric, top, back, left,
and so on and so forth.
And they're all found here in this icon.
So, here is the front, right, and bottom, isometric.
Normal means normal to the selected plane or plane face.
Here's illustrations of those views.
View orientation also as shown here.
Top, front, right, isometric, and trimetric.
Trimetric, the isometric is one in which the angle here
of this edge, of the"z" in this case 30 degrees with the horizontal
and the X is also 30 degrees introspect to the horizontal.
But sometimes it is difficult to visualize the object
by looking at it in isometric.
So, in fact, trimetric because it's not symmetric,
is usually easier to use and visualize.
Default planes, front, top, and right, which we had before.
And so on.
The isometric view displays the part with height, width,
equally foreshortened and this angle here as I indicated was 30
and 30, and the Y is vertical.
You can also view the section view
by simply creating the location of your cutting plane.
Very, very important.
When you're doing sketches, OK,
there's three different conditions
that your sketch can fall under.
One is something called
under defined meaning additional dimensions
or relations are required.
So, that particular sketch is not completely defined.
And you know that it is completely defined
or under defined because it is shown in blue.
So, when these sides are blue, that means the length
of this side and this side are not completely defined.
When something is fully defined, there's no additional dimensions
or relationships required to fully define the sketch.
So, for instance when I say this is 40 and this is 80.
This becomes completely defined, and the lines turn black.
On the other hand, sometimes you may have something that's
over defined, meaning it contains conflicting information
either in dimensions, relations, or both.
And when something is over defined you will know
because the computer will complain.
It will show those entities as red.
Here's an example here.
