- [Narrator] As you're working with
your curves and surfaces,
you want to make sure that they look good.
One great way to do that
is to visualize the control points.
Now, the control points that we use here
for manipulating the surface
can be displayed using a tool called Apply Dress Up.
I can show control points and segmentation.
I'll turn both of those on, select okay,
and as we can see,
I have my control points displayed in this blue frame.
These dashed lines that you see
are just the isoparms across the surface.
Go ahead and hide that.
Now, I'm going to do the same thing
with this corner surface here.
Pick my corner surface.
Turn on the display, control point segmentation,
and hit apply.
Now this is a very complex surface and I know this
because as I visualize it,
I have a lot of control points.
I also have these solid font lines across the surface.
These solid font lines are the segmentation,
or they're invisible patches on the surface
across those boundaries.
So this is a very complex surface.
If you're seeing a little bit too much,
you can turn off that segmentation and hit apply,
and now you just see the actual control points.
If you just want to get rid of the control points
and turn on segmentation,
you can do the same as well.
Once I have a dress up applied,
you'll notice it doesn't put anything in the tree for me.
So, one way I can turn those off
is just to pick the surface
and turn off the applied dress up or remove dress up.
So it's like a switch, on and off.
Let me go ahead and show this surface.
So now if I go back in, I have those control points.
If I click on the control point icon
and look at those control points,
you can see what ends up happening is
they turn green and these are now active
for me to pull or push the surface as I see fit.
I select okay and that display now comes back and returns.
So, this is a really good way to verify
that the surface you're looking at
is nice and smooth and clean.
'Cause if you see any odd interruptions
in that control point display,
you'll know that there's something weird going on
with the surface.
