00:00:00.03 --> 00:00:01.02

- [Instructor] In this movie,



2

00:00:01.02 --> 00:00:03.00

we're going to bevel the edges of the note



3

00:00:03.00 --> 00:00:06.01

in order to convert this

relatively staid version



4

00:00:06.01 --> 00:00:07.00

of the artwork



5

00:00:07.00 --> 00:00:09.09

into this more compelling effect here.



6

00:00:09.09 --> 00:00:11.04

All right, now as before,



7

00:00:11.04 --> 00:00:12.07

my notes are still selected.



8

00:00:12.07 --> 00:00:14.04

It's just that my edges are hidden.



9

00:00:14.04 --> 00:00:15.04

And you can see that's the fact



10

00:00:15.04 --> 00:00:18.07

if I press Control + H or

Command + H on the Mac.



11

00:00:18.07 --> 00:00:20.00

I'm going to leave them hidden,



12

00:00:20.00 --> 00:00:23.05

and then I'll go ahead and

click 3D Extrude and Bevel



13

00:00:23.05 --> 00:00:25.07

here inside the appearance panel,



14

00:00:25.07 --> 00:00:27.08

and I'll turn on the preview checkbox



15

00:00:27.08 --> 00:00:29.07

so I can see what I'm doing.



16

00:00:29.07 --> 00:00:33.03

Now, notice this Extrude

and Bevel area right here.



17

00:00:33.03 --> 00:00:35.09

We've already seen what

happens if you raise



18

00:00:35.09 --> 00:00:38.05

or lower the extrusion depth,



19

00:00:38.05 --> 00:00:41.05

but let's say that I take

it up just a little bit here



20

00:00:41.05 --> 00:00:44.05

and I switch to one of the many bevels



21

00:00:44.05 --> 00:00:46.02

which are available to me.



22

00:00:46.02 --> 00:00:48.01

And notice if you look very closely here



23

00:00:48.01 --> 00:00:52.01

you can see these little

cross-sections of the bevels.



24

00:00:52.01 --> 00:00:53.04

And so the classic bevel



25

00:00:53.04 --> 00:00:55.08

is just going to bend the edges inward,



26

00:00:55.08 --> 00:00:57.07

both along the front edges



27

00:00:57.07 --> 00:01:00.04

and the back edges, as well.



28

00:01:00.04 --> 00:01:03.05

Well, we've got a lot of

different options to choose from,



29

00:01:03.05 --> 00:01:06.04

some of which are pretty

darn entertaining.



30

00:01:06.04 --> 00:01:08.07

And so notice in the case of rolling



31

00:01:08.07 --> 00:01:11.02

that we're rolling that bevel



32

00:01:11.02 --> 00:01:13.08

along the entire extruded edge.



33

00:01:13.08 --> 00:01:16.05

So if I were to increase

that extrude depth value,



34

00:01:16.05 --> 00:01:20.00

then I will distribute that rolling edge



35

00:01:20.00 --> 00:01:23.07

across the Z surface of the notes.



36

00:01:23.07 --> 00:01:26.01

All right, but just for the

sake of demonstration here,



37

00:01:26.01 --> 00:01:27.07

I'm going to switch to this guy,



38

00:01:27.07 --> 00:01:28.09

Complex 1.



39

00:01:28.09 --> 00:01:30.07

It's not necessarily my favorite effect,



40

00:01:30.07 --> 00:01:33.08

but it does give us a

sense of what's going on.



41

00:01:33.08 --> 00:01:34.08

So once again,



42

00:01:34.08 --> 00:01:37.02

if I change the extrude depth value,



43

00:01:37.02 --> 00:01:41.00

I am changing the depth of that bevel.



44

00:01:41.00 --> 00:01:43.08

You also have control over the height,



45

00:01:43.08 --> 00:01:45.02

which to my way of thinking



46

00:01:45.02 --> 00:01:47.03

seems more like the width of the bevel.



47

00:01:47.03 --> 00:01:50.00

But notice as I increase that height value



48

00:01:50.00 --> 00:01:53.06

that I am increasing the size of the bevel



49

00:01:53.06 --> 00:01:55.05

all the way around.



50

00:01:55.05 --> 00:01:57.09

Now, you may end up seeing

this little warning down here,



51

00:01:57.09 --> 00:02:00.09

bevel self-intersection may have occurred,



52

00:02:00.09 --> 00:02:02.01

and what that's telling you



53

00:02:02.01 --> 00:02:05.07

is that your bevel has

probably gone very wrong,



54

00:02:05.07 --> 00:02:08.00

and you should just keep

an eye on that preview



55

00:02:08.00 --> 00:02:10.07

in order to try to fix things.



56

00:02:10.07 --> 00:02:13.02

All right, we also have

this option right here



57

00:02:13.02 --> 00:02:16.09

which allows you to

either set the bevel out



58

00:02:16.09 --> 00:02:20.02

or to set it inside the path outlines.



59

00:02:20.02 --> 00:02:22.08

I'm going to leave it outside

the outlines for a moment



60

00:02:22.08 --> 00:02:25.08

so that I can show you

this final option, Cap,



61

00:02:25.08 --> 00:02:28.07

which determines whether

you're seeing a face



62

00:02:28.07 --> 00:02:31.09

to your 3D object or not.



63

00:02:31.09 --> 00:02:33.08

Notice if I select the second icon,



64

00:02:33.08 --> 00:02:36.07

then the face of my objects go away



65

00:02:36.07 --> 00:02:40.04

and all I'm left with is

the extrude and bevel.



66

00:02:40.04 --> 00:02:42.03

All right, I'm going

to bring the caps back



67

00:02:42.03 --> 00:02:44.02

and I'm going to switch to classic



68

00:02:44.02 --> 00:02:46.05

because I think it looks best.



69

00:02:46.05 --> 00:02:48.03

I'm going to go ahead and

take that height value



70

00:02:48.03 --> 00:02:49.09

down to 10 points,



71

00:02:49.09 --> 00:02:52.09

and I'll set the bevel

inside the path outline,



72

00:02:52.09 --> 00:02:54.02

like so.



73

00:02:54.02 --> 00:02:56.06

All right, now there's just

one more change I want to make



74

00:02:56.06 --> 00:02:59.04

just to light some of these

edges a little differently.



75

00:02:59.04 --> 00:03:01.03

I'm going to add yet another light



76

00:03:01.03 --> 00:03:03.03

by clicking on the little page icon.



77

00:03:03.03 --> 00:03:06.03

Then I'm going to drag this

guy all the way down here



78

00:03:06.03 --> 00:03:08.03

to the bottom of the sphere



79

00:03:08.03 --> 00:03:10.09

and move it around until I come up



80

00:03:10.09 --> 00:03:13.00

with a high degree of contrast.



81

00:03:13.00 --> 00:03:15.03

And so something like this



82

00:03:15.03 --> 00:03:17.03

might end up looking pretty darn good.



83

00:03:17.03 --> 00:03:18.02

And if you like,



84

00:03:18.02 --> 00:03:20.06

you can go ahead and

modify the intensity value.



85

00:03:20.06 --> 00:03:23.06

I'm going to take it

down to 80%, let's say,



86

00:03:23.06 --> 00:03:26.04

in order to achieve this effect here.



87

00:03:26.04 --> 00:03:29.00

And now I'll take my extrude depth value



88

00:03:29.00 --> 00:03:30.08

back down to 60



89

00:03:30.08 --> 00:03:35.01

and I'll go ahead and click

OK to accept that change.



90

00:03:35.01 --> 00:03:36.04

And that, my friends,



91

00:03:36.04 --> 00:03:38.01

is how you add beveled edges



92

00:03:38.01 --> 00:03:41.01

to your extruded 3D objects



93

00:03:41.01 --> 00:03:43.01

here inside Illustrator.
