- [Narrator] Now I wanna talk about a tool called fill.
Now, as far as this tool goes, it's really powerful.
Just be very careful with the way you use it,
because it can create very heavy surfaces.
Think of it as basically a patch.
You're trying to just fill in something,
it's kind of a quick and dirty thing,
you just wanna get something in.
Let's say like this three sided surface,
fill in the three sided surface, it'll do it.
It'll do five sided, six sided,
as many open edges as you have, it'll fill those things in.
But again, what the surface does internally is very heavy.
It'll also create a parametrically rectangular surface.
So even if I pick three sides,
internally to that surface,
it will actually have four sides
but it may be much larger than
the actual opening that it's filling.
So with that, I will go into fill.
This tiny little icon right here.
And the way this works is,
in this case I have a singular surface
or if you have different surfaces it'll still work.
You have to just make sure
that you're picking contiguous end point,
to end point, to end point.
Meaning if an edge runs longer,
you may have to turn on the stop at intersection
to get it to stop at the specific end point.
Because this is all one big sort of service
then I have just the interior curves.
So for this, I'll pick my curve one,
curve two, and curve three.
As soon as I picked that third curve you notice,
it recognizes that it's a closed boundary
and it fills it in.
I also have what's called patch into part.
Basically, it's gonna patch this in,
make it a part of the initial surface.
If I turn that off,
it will leave it as an individual surface all to its own.
So for example, if I select ok now,
you'll see that I have this surface.
If I have that turned on, it's like ok.
You'll notice that it became a part of the initial surface.
It automatically patched it, or sewed it in.
So I'll double click on that again.
I have some other options in here that I can use.
There's a shape control method.
One of 'ems really kinda neat.
Just to show you what
the shape controls basically all about.
You can have curves that sort of bridge the gap.
You can use curves or facet bodies.
Or for this, just to show you with fullness.
What it does is it gives you a control point offset
and in this case it's basically pretty much smack dab
in the middle of that surface.
And you may be able to offset.
As you can see it's puffing it out a little bit.
Or come in, create a little divot.
And this can, again, can be kinda useful if you're trying
to basically fill in an area.
Sometimes it may give you a sharp peak somewhere in
the middle and this allows you
to just sort of flatten it out.
Or again you may have a curve kind of like a section
that you want this surface to run through
and you can use that.
Fit to curves option is there as well.
Good tool.
Just be careful, again, with the way you use it
because it can create very heavy surfaces parametrically.
