- [Instructor] Now I want to talk about extrude and revolve.
In generative shape design, we have extrude and revolve.
The revolve works basically the same
as it does in the freestyle.
Click on Revolve, specify your profile,
specify your Revolution Axis,
and then determine your angular limits.
The extrude function in generative shape design
allows you to specify a profile.
In this case it's a plane or curve,
so it has a normal.
If I want to, I can specify a direction,
and once again determine your limits.
You'll notice in the tree, it calls it out
as an extrude one.
Go ahead and hide that.
Now I'm going to switch to the Freestyle workbench,
and within the Freestyle Workbench,
I have that revolve tool.
Again this is basically the same
as it is in generative shape.
The difference is the Extrude tool.
With Extrude surface, you'll see
that this looks a bit different.
What element do I want to extrude?
This curve.
And for direction, I have along a compass
or normal to curve.
You'll see here this is a plane or curve.
It shoots it off normal to that curve.
If I say compass direction,
I grab my compass and drop it on this direction,
you'll see it now controls,
grab this a drag this out,
that direction.
If I move the compass off of that curve, you'll notice
that the surface goes right along with it, dynamically.
Once I select OK,
the surface is no longer called an Extrude,
it's just simply a NURBS surface.
So the big differences here are the end result,
the end result in the Freestyle Extrude is a NURBS surface.
