- [Instructor] Now, I wanna talk about a tool called Swept.
Not Sweep Along Guide, it's called Swept.
It does something similar to Sweep Along Guide,
where it takes a section and sweeps it along a guide string,
but it's far more powerful.
So we go under this Surface tab and we'll go into Swept.
Now, the first thing I want you to notice,
let me close some of these up, so we can actually see
more of the menu, go ahead and close this.
What I want you to notice is first,
that there's a lot more options with the Swept function
than the Sweep Along Guide.
We have sections.
Plural.
We can have more than one section.
In fact, we can have over 100 sections, if need be.
If you're doing that, you have to have a really good reason.
I'd say you'd probably, maybe you're doing
like a fan blade or rotor, something like that
where you need specific shapes at specific locations
and that's where you do that.
But typically speaking, the fewer sections that you have,
the better off in the long-run.
And you can have up to three guides.
All right, so there's a maximum of three guides.
So the way this works, just come over here,
bring this out of the way.
I'm gonna pick my first section.
Now, you'll notice that when I pick my first section,
I get this little arrow.
This arrow is indicating the direction that the
section surface here is going to be built.
The reason why this is important is when I pick more
than one section.
In this case, I'm just gonna leave it at one.
And then I'm just gonna come down to Guides
and pick the guide curve and you'll see,
it sweeps along that guide.
There are an incredible amount of options
when it comes to the Swept tool.
You'll notice down here, under Section Options,
I have preserve shape, I have parameter.
Where's the section relative to the guide?
I have orientation methods, I have scaling methods.
So for example, it's a constant scale of one,
I can come over and say, maybe I want this bigger.
So you can scale this thing as it sweeps along that guide
or is swept along that guide.
Make sure I say the right one for you.
I also have the ability to do blending functions
where it gets bigger, smaller as it goes along as well.
So I have tons of options as far as what I can with a Swept.
Like I said, it's incredibly powerful.
For now, I'm just gonna leave it at constant.
And I just wanna talk about the various things you can do
when you have multiple sections and multiple guides.
So here, I have a single section and a single guide.
And basically, it just takes that and sweeps it along.
Just gonna cancel.
I'm gonna go back into my Swept tool.
Close this off, close that off.
Now, I'm gonna pick section number one.
And this time, I'm gonna down to Guides again.
Pick guide one and I wanna do what's called add a new set.
If I look at this list,
you'll see there's my guide curve one.
I just can't go and pick the next curve.
I have to tell it I'm adding a new set.
Couple ways I can do that, I can use this icon
or you can use the middle mouse button.
So if I click the wheel or if you have a button,
just simply click it once, it'll ask for the next guide.
Or again, I can just simply hit that icon.
So here, I'm gonna pick this guide.
And now, you see that it is selected, it's sweeping along
both of those guides.
It's being pulled along both.
Some of the options down here will have changed.
You'll notice the scaling method,
I only have a couple of options here.
I have uniform, lateral, another curve.
Just to give you an idea, you'll see it's taking that.
Now, it's scaling it laterally.
Basically, it maintains the height as it moves it along.
Or if I say something like uniform,
as it gets further apart, it gets taller as it gets closer.
As the guides get closer to one another, they get shorter,
that type of thing.
So you have that option.
Now, as far as using a third guide curve.
The third guide curve would define that scaling.
So if I did have another guide curve at the top,
it would scale that for me and I would actually do away
with all of these scaling methods.
So it's one of those tools where as you're using it,
the menu changes.
So if you're looking for a specific function,
make sure you have the correct amount of sections
and guides picked to find that specific function.
So I'm gonna go ahead and
cancel this out to basically restart the menu.
Go back into Swept.
Now, I'm gonna pick, in this case, section curve one.
New set, I'm gonna pick section curve two.
And this is where those arrows come in very important.
Remember, this is the direction the surface
is going to be built.
So here, I'm just gonna add a guide curve just to show you.
It's being swept along that guide.
If one of these arrows were reversed,
I end up with a lovely little bow tie.
So that's why those arrows are important.
You wanna make sure that they always point
in the same direction.
Now, with this, I picked two sections,
so you'll see I have again several options.
It's when I start picking guides that a lot of these options
begin changing and really disappearing.
So you wanna make sure that as you're picking your options,
again, you have the right amount of sections picked,
right amount of guides picked to get the various
section options and settings that you're maybe looking for.
Again, 'cause they change.
So if I pick the second guide curve, come in here, and
hit New Set,
pick this guide curve, you'll see now,
it is being forced along that guide curve.
And for the guides, the arrows aren't nearly as important.
As you can see, it still builds it.
It knows that it's going to basically use that
as a guide curve.
So for the guides, it's not nearly as important
as it is for the sections.
So if I try reversing this for the section again,
you'll see I start getting error messages,
I get my little bow tie.
So the important takeaway here is
making sure the sections are all aligned.
And hit OK, create that surface.
Now, I do have another
sketch here in the tree.
I'm gonna right-mouse click on it and show it.
So if I want to, say, for instance,
I'm gonna double-click on this Swept.
If I need to add a set, let's say, in between
Section One and Two, if I just come in here now
and leave it at Section Two by default and pick this,
what's gonna happen is it's gonna say,
hey, I can't do a thing, right.
I never told it to add a new set.
So it thinks you're adding this as part of the section.
That's not what I want.
So I'm just gonna deselect that,
hold the Shift key down, deselect it.
So I'm going to add a new set.
Now, when I add this in, you'll see
again, some odd behavior.
It's going from Section One to Section Two,
back up to Section Three.
If that's not what you want, it very well may be,
you may have to use a singularity mill to make this thing.
Right, quantum manufacturing.
I'm just gonna take Section Three and move this up.
So I've just changed the order of those sections.
So here, I'm able to move those things around
and make sure that I have those sections picked correctly.
Now, if I come back down a little ways,
you'll see here again I have various interpolation methods.
So basically, how is this shape changing as it goes from
section to section?
And right now, it's linear, so it's basically just going
straight across, straight across.
If I change this to cubic, you'll notice I get
a very different shape.
So here, it is actually going along
and
it's coming in
with a nice smooth transition and coming out
with a nice smooth transition and then all the way down
and through both.
So as I said, depending upon how many sections
you have picked, depending upon how many guides have picked,
you end up with very different menu options.
So just pay attention to what you're picking,
how you're picking it, the order of things
that you're picking, that type of thing,
because it all affects that surface.
So this Swept tool is really powerful.
There's so many options, there's literally dozens
and dozens of options within this tool.
So get familiar with it, start using it.
I almost expressly use Swept
over any other of the Sweep tools.
I may use a Sweep Along Guide if I have a very simple shape
that I'm just gonna sweep that shape along.
Sometimes I may even use Swept because there may be
additional edits that I have to go through after
the surface has been created, I may have to go back
and add something or change something.
This just gives me more options.
As I scroll back down, I want you to notice again
I do have body types for sheet
because I am using open profiles.
I have a sheet body that's gonna be created.
If I do use close profiles, I can make it a sheet again
and I also have the option to create a solid.
Here, there's no solid to be made.
There's no offset options here to make a solid,
so it doesn't matter what I set this to now.
An open profile will always create
for me a sheet body.
If it's closed, then I can toggle between solid and sheet
and actually see the difference.
