- [Instructor] The Boundary Boss Base command,
is not as common as a regular Extrude or Revolved feature.
However, it's extremely powerful and it's similar,
to both a Sweep as well as a Loft.
So let me show you what I have on the screen here.
I just have a basic circle.
And if I take a look at that sketch, I've got a circle,
a certain distance from the origin.
And now if I exit out of that, I want to grab a new plane,
that's perpendicular to the one I'm working on.
So right here, the front plane is perpendicular,
to what I started with.
And let's go ahead and create a sketch on that plane.
Now I want to start with a short line segment,
so I'm not going to try to snap over here to that shape.
I want to just go a little distance away from that,
click once, click again where you want to stop
and then escape out of that.
So I have a 1 little short line segment
and then what I want to do is grab the tangent arc
and I want to start right there at the end
and drag this down, so it's about at the bottom,
where that origin is, click there once.
Now let's go ahead and grab a center line,
so I'm starting at the origin.
I'm going to bring that out the end of my point
and then I'm going to make sure this is a horizontal line.
Now I want to do exactly the same thing,
for the bottom of the circle.
So get close, draw a little line, and I can go over here
and transition over here to a tangent arc.
And then what I want to do is I want to come over here again
and create a line which is actually a center line
and snap that to that point so that I can then,
add a relationship between this line here,
hold on control on the keyboard,
grab that arc there and then say tangent.
So now we know that's coming straight down,
into that line.
Right, now what we need to do is connect the dots, right?
So if I spin this around in 3-D,
you can see that this point here wants to connect,
to that circle there and this point down here,
wants to connect to that circle there.
If you're working in a flat view,
so you're looking only at the side, it's harder to do this.
So it's a good idea to rotate this around,
so you're looking at an isometric or 3-D type view,
before you start adding this relationship.
So what I want to do is I want to choose the point.
Now I want to hold down control my keyboard
and choose the circle.
And as soon as I let go,
I get this option here called Pierce
or it's over here as well.
Pierce, click on that and it pierces into that circle.
Do the exact same thing at the bottom here,
click on that point, hold on control, grab the circle
and hit Pierce.
So now we have everything connected up,
the exact way we want.
And what we want to do is we want to take this circle
and we want to guide that circle,
down into this area over here,
to create a little bit more of an obround circle,
in this area here.
So that's what's going to happen when this command is run.
All right, so I want to go ahead
and exit out of this sketch.
Now go over here to features,
come over here to Boundary Boss or Base.
It's going to give you a little heads up that says
"At least 2 profiles are required,
to make an and boundary surface, 3 are required,
to make a closed boundary surface."
Click OK.
And what we need here is direction 1, is or our,
that circle, right?
And then for our direction 2,
is we're going to choose these lines here
and I'm going to go ahead and choose both of those,
click OK and you can see what happens there
and then do the same thing at the top,
grab that line there and that line there,
click OK and now we've added both of those lines,
to guide our shapes.
So we're taking this basic circle,
which is round where it starts
and then we're making it out when we get down to here.
So just that easily click OK,
give it a second to think about it
and there's our shape.
So that's a really powerful command
and allows you to do a lot.
Now we're only scratching the surface with this, right?
This is a command that has a lot of potential,
a lot of power.
This is one of the most basic things you can do with it,
but it's cool, be able to mesh that together.
It's kind of like a Sweep mixed with a Loft command.
Now to finish this off,
let's go ahead and grab the mirror command.
I'm going to mirror this around this face right here
and the body or the feature, I want to choose a body itself,
by choosing this one here, click OK.
And there, you can see my finished up little handle.
So again, that is the Boundary Boss or Base.
It's not as common of a tool inside of Solid works
but it's definitely extremely powerful.
