- [Instructor] Now a Fit Spline works pretty easily.
Basically, what it does is it takes geometry that you have,
that's existing,
if you select it all then just click on Fit Spline,
it's going to fit a spline roughly to that geometry.
You can set a specific tolerance for how close
or how far it needs to be to what you're showing.
You can also delete the original geometry,
create a closed spline, if you want,
which is a little bit more complex,
it'll need to wrap around and completely close itself,
and you can also make it constrained or unconstrained,
change your preview options with inflection points,
and you can also go in and edit the chaining if you want.
And that's, I believe, when you use the fixed option here.
Just waiting for my graphics to check up.
But at any rate, file, un-click that,
and hit delete geometry.
If I hit accept, now I get a smooth spline
that fits the curvature of the original shape I had there.
You can see here, though, I can't quite grab it
and drag it the way I used to.
Now it's just a fixed shape,
so you'll want to make sure when you do that
that you add insertion points into it as one of your options
and make it flexible.
Now you can also do this with a really complex spline.
So I can say fit spline to that,
and have it kind of clean up the spline that I have there,
and maybe if I increase my tolerance,
I can make it even smoother,
and kind of ignore some of the extremeness of that shape.
Go ahead and click okay, and now I've replicated that shape,
but it's basically a single unit, if you will,
like a block that you can drag around
and you can't change its shape anymore.
So that's one thing to remember
when you make the fit spline,
is you're not really going to be able to edit it
after the fact, so make sure when you do that
you toggle the correct options,
or you can always go back and add things
like insertion points and tangency control.
