>> This is a tutorial on lab number 15.
A lab on solid modeling.
The first thing you want to do probably is
to change our workspace from drafting and annotating --
annotation -- to basic, 3D basics.
And then we create layers.
I've created layers.
Here's the layer, layer property manager.
We have created a construction layer that's white,
an object layer that's blue, an object layer that's .3.
And we close that layers property manager.
And then we turn on some of our tabs here, drafting aids.
So the grid, the snap, and also polar and also object snap.
And then we set the current layer to object.
Forgot to do that.
And then we'll change our view to SE isometric.
So we can see the model as it's being created.
We start by creating a box.
First corner is at the origin, 0 comma 0 comma 0.
And then second point is 4.5 comma 3.5 comma 0.
And then we are going to work on the bottom part
and the thickness or the height of that is .75.
Let's zoom in.
And we create another box
on the left side using this as the first corner.
And the second corner will be at --
make sure that it's relative coordinates --
at 1 comma 3.5 comma 0.
Enter. And the height of that box is 1.95.
Which is the overall 2.7 minus .75.
The thickness of the bottom.
Now we're going to union combine these 2 solids
by using the union command.
This one and this one.
Press enter.
And notice, now, the two have been combined to a single solid.
Next thing we're going to do is create a box somewhere out here,
an arbitrary location outside the solid that we have so far.
Here's the first corner.
And second corner is at 1 comma 1 comma 0 because we're --
and the height is also 1 --
because we're doing a 1 by 1 by 1 box.
And then move this using the midpoint of the small box
to the midpoint of this edge of the existing solid.
So that's the correct location.
And then we subtract the bigger one.
Enter. The smaller one.
Enter. Let's turn off our gird so we can see this better.
Next thing we're going to do is, again,
on some arbitrary location, let's create a box
and the first -- second location is
at coordinates 1.5 comma 1.1, 0.
And the height is .75.
And we're going to create a cylinder.
OK. With center is at the midpoint of this lower left edge
of this tiny box right here.
And the radius is .55.
And the height, again, is .75.
The same height as the box.
So we've created this.
And then we're going to union these two,
the cylinder and this box.
Press enter.
And then we're going to move that solid there.
Press enter.
Here's the first base point to the midpoint.
The second base point is midpoint of this.
Then subtract from the bigger one.
Press enter.
Object subtract.
The smaller one.
Next thing we're going to do is we're going to chamfer.
So chamfer at the edge over here.
And then we select distance as the option.
For the first distance we type 1 comma --
and the second distance is .6.
And press enter twice.
That completes the chamfer.
And repeat the chamfer command on this other edge here.
Now since our distance is already set correctly,
we just press enter twice.
And we're done with that.
And then we're going to --
oh, repeat the chamfer command again.
This time I'm going to chamfer this edge here at the bottom.
I'll click on distance again to reset the distance
as distance 1 is equal to .6 and distance 2 is 1.5.
Looks correct.
Press enter twice.
Repeat chamfer again.
This time, this corner -- this edge here.
The distance is already set to press enter twice.
Next thing we're going to do is we're going
to create the cylinder.
In order to do that, we need to change using three points.
Here's the origin, is the point on the x-axis.
And this is the point on the y-axis.
Take note that x-y plane is now on the left plane.
Now we're going to create a cylinder.
And the coordinates of the center
of the cylinder are half the depth, which is 1.75 comma --
and it's going to be at the height of 1.1,
which is 2.7 minus 1.6 and z of zero.
And this is the center.
And the radius is .25.
And the height of the cylinder is 1.
And then we're going to subtract from the big solid.
Press enter.
Object to subtract.
The small cylinder.
We're done.
Now we can look at different ways of visualizing it.
So I'm going to go to visualize.
I'm going to use realistic.
OK. That's the realistic.
And we can orbit it.
So we can look at it.
And let's try another visualization style here.
Conceptual.
And let's rotate again.
Looks like we're done.
