- [Instructor] Alright, so in a previous movie I showed you
what happens if you combine strokes
along with the extrude and bevel effect.
In this movie, I'll show you what happens
when you combine strokes with 3D revolve.
And just to give you a sense
for what this looks like before it's revolved,
I'll select the object and then here inside
the appearance panel I'll turn off the 3D revolve effect.
And so what we have is a handful of bars
that have been cut into the shape of a half circle.
And so just for laris, I'm going to show you
how I put together this entire project.
I'll switch back over to the layers panel
and I'll turn off that top layer.
And I'll turn on this layer called blend.
So what we have here is a circle, quite obviously.
And then we have a bunch of rectangles.
And so I drew the top rectangle.
I went ahead and copied it to create the bottom one
and then I created an object blend between them
with a total of five steps.
And so what we need to do is take these rectangles
and cut them into the shape of a half circle.
And so I'll start by selecting the rectangles
and then going up to the object menu and choosing
the expand command.
The default settings are just fine, at which point
I'll click okay.
And now we have a total of seven rectangles,
combined into a single group.
Alright now I'll select the big circle,
we need to turn it into a half circle
by switching to the white arrow tool,
which you can do by pressing the A key.
And then I'll select that left-hand point right there
and I'll press the backspace key
or the delete key on the Mac, to get rid of it.
Now, if we wanted to non-destructively crop the rectangles,
we would turn this whole thing into a clipping mask.
But while you can technically apply 3D commands
to clipping masks, it's not a fun experience.
It takes forever.
So the better way to work is to press the V key
to switch back to the black arrow tool.
And shift click on any of the rectangles to select them.
And then go up to the window menu
and choose the pathfinder command to bring up
the pathfinder panel.
And then go ahead and click on the divide icon,
which is the first one in the second row,
in order to divide all the shapes apart.
Alright, now you can hide the pathfinder panel.
That ends up giving us a group,
which is not something we want.
So go up to the object menu and choose the ungroup command
in order to break everybody apart.
And then I'll partially marquis these right-hand shapes
and press the backspace key or the delete key
to get rid of them.
And then I'll grab these left-hand shapes
and get rid of them too.
And finally, I'll select any one of the light gray shapes
and then I'll click on this icon up in the control panel
select similar objects, to select all the light gray shapes.
And then I'll press the backspace key
or the delete key on the Mac, to get rid of them.
Alright, now let's just grab all the dark gray bars.
And I'm going to change their fill colors to
this darker shade of pink that begins R=158.
Alright, now let's revolve the shapes
by going up to the effect menu,
choosing 3D and then choosing revolve.
And now I'll go ahead and turn on the preview checkbox
so we can see what we're doing.
And at this point, it's a little bit difficult to tell
what's going on.
So I'm going to reposition the light source here.
And I'm going to adjust a few settings.
I'll leave the light intensity at 100%.
I'll take the ambient light down to 20%
so that we have a little bit of extra contrast.
I'll change the highlight intensity to 100%.
I'll also change the highlight size to 100%.
And then, just so we get smoother results,
I'll change the blend steps to 100.
At which point we end up with something
that's still pretty darn messy.
And so I'm just going to dial in some positioning values here.
I'm going to change that X axis value,
which represents the pitch, to 12%.
I'll change the YA to -30.
And then I'll change the roll to 10
and finally, I'll increase
the perspective value to 50 degrees.
At which point you can see that we're ending up
with a pretty weird looking effect.
And we might be able to make more sense of it,
if we weren't seeing the wire frames.
And so I'm just going to press the down arrow key
to reduce the angle value to 359.
And then I'll press the up arrow key
to take it back up to 360 degrees
which is ultimately what we want.
Now the reason our strange object
is sort of caving in on itself,
is that every one of these shapes,
is an independent path outline.
So it's being affected differently than its neighbor.
We'll take care of that in a moment.
But first, I'm going to change the shading color
from black to custom.
And then I'll go ahead and click
on that color swatch there.
A hue value of 0 degrees is fine.
Same with the saturation value of 100%.
But I'm going to take the brightness value down to 20%.
And click okay.
At which point, we'll see the effect applied.
Alright now go ahead and click okay.
Now, the wonderful thing about this
is we can fix this effect.
Not by grouping the paths together,
but rather, by going to the object menu,
choosing compound path, and choosing make.
At which point, the 3D effect survives beautifully.
And you can see that over here in the appearance panel.
Notice that the 3D revolve effect is still intact.
Alright, but not quite loving the lighting at this point.
So I'm going to click on 3D revolve to revisit my settings.
Turn on the preview checkbox
so I can tell what the heck I'm doing.
And then I'll add another light
by clicking on the little page icon.
And I'll drag this guy down to right about here,
I think is going to work,
and then I'll send it to back
by clicking on this first icon.
And we end up with this effect here,
which is pretty cool.
But I'm not liking the fact
that the areas underneath the slabs are a bright pink.
I want them to be black instead.
So, we'll go ahead and click okay,
in order to accept what I have so far.
And what I'm going to do, is apply a stroke.
So I'll go ahead and select the stroke
here inside the appearance panel
and I'll change it to black.
And that's going to change everything to black, by the way.
Because the stroke is wrapped around the fill.
Now one way to make things a little bit better here
is to drag the stroke down below the fill.
So that we're not entirely covering up the fill.
The problem is, the stroke is still wrapped around
each one of these objects.
And the only reason, incidentally,
that we're seeing some brighter areas that are not black,
is because I set my shadow color to something brighter
than the stroke.
Alright so we need to make a few adjustments.
First of all, we want to reduce the stroke value
to something very, very low.
Such as 0.05 points, which is going to work out.
And this is stuff I figured out just by trial and error.
And notice that that helps a bunch of the slabs,
but not quite all of them.
The next thing you want to do is, with the stroke selected,
go up to the effect menu, choose distort and transform,
and choose the transform command.
Or if you loaded D keys, you can press control E
or command E on the Mac.
And then go ahead and turn on the preview checkbox.
Click in the horizontal move value right there
and just press the down arrow key.
In order to scoot the strokes 1 point to the left.
And that ends up moving them away from the edges
of the path outlines.
At which point, you can go ahead and click okay
to accept that change.
So again, I really want you to understand
what's going on here
because it's a little bit obscure.
I'm going to go zoom in, way in, on the artwork
and I'll turn off the 3D revolve effect right there
and I'll press control H or command H on the Mac
to hide the edges.
And we're still not zoomed in far enough,
so I'll press control and space bar
or command and space bar on the Mac.
And then I'll just drag to zoom in.
And now, I think you can begin
to see the stroke right there.
Notice it's very tiny, but it's moved away from
the edge of the fill.
And as a result, it's covering up the top of the shape.
And if I scroll down here quite a bit,
because I'm zoomed in beyond 10,000%,
it's also showing up along the bottom of the path outline.
And as a result, it's covering up that bottom edge.
Alright, I'll press control 0 or command 0 on the Mac
to zoom back out.
And then I'll turn on 3D revolve.
Now, I'm not very happy with the fact that the bottoms
are kind of this dark gray,
instead of being absolutely black.
And so to fix that I'll click on 3D revolve,
I'll turn on the preview checkbox
and this is ultimately a lighting problem, by the way.
I'm guessing that this bottom light
is catching the bottom of each one of these slabs.
And so I'm going to grab this guy and drag him farther down.
And notice that it's caught on my cursor.
That happens sometimes.
And you're not going to see the effect previewed
until you manage to click
and get that thing off your cursor.
So I don't know if that's a problem you're going to run
into or not, but it's definitely a problem
that I've been experiencing.
As you can see, as soon as you drag that guy
far enough down, the bottoms of your slabs
end up turning absolutely black.
At which point, I'll click okay to accept that change.
Now the other thing I want you to notice here,
I'm going to go ahead and zoom in a little bit,
is these edges right here.
They look a little bit scrapy when you're zoomed out,
but if you zoom in, you'll see that they're actually
very smooth, but they are going to be there.
And that's because this stroke, is moved away 1 point
from the edge of the fill.
Now, you could try to fix that problem
by clicking on the word transform
and trying out different values,
but no matter what you do, you're going to have
some degree of edge right there.
That's just something I want you to be aware of.
Alright, I'm going to deselect my artwork
by pressing control shift A.
And then I'll press the F key a couple of times
to switch to the full screen mode.
And I'll zoom into my artwork.
And that, folks, is at least one example
of how you might combine a stroke
along with a 3D revolve effect, here inside Illustrator.
