1
00:00:00.05 --> 00:00:02.03
- [Voiceover] Alright, let's
take a look at object blending

2
00:00:02.03 --> 00:00:04.05
where Illustrator automatically creates

3
00:00:04.05 --> 00:00:07.04
a bunch of intervals between two shapes.

4
00:00:07.04 --> 00:00:08.09
And so the first thing I'm gonna do is

5
00:00:08.09 --> 00:00:11.05
go up to file menu and
choose "New from Template"

6
00:00:11.05 --> 00:00:13.00
or I could press "control shift n"

7
00:00:13.00 --> 00:00:14.06
or "command shift n" on the Mac

8
00:00:14.06 --> 00:00:15.08
then I'll go ahead and open up

9
00:00:15.08 --> 00:00:17.08
my center guides document there.

10
00:00:17.08 --> 00:00:21.04
And I'll start by drawing
just a plain old rectangle

11
00:00:21.04 --> 00:00:22.09
and of course you can
get the rectangle tool

12
00:00:22.09 --> 00:00:24.06
by pressing the "m" key.

13
00:00:24.06 --> 00:00:25.05
Now I'll actually go ahead

14
00:00:25.05 --> 00:00:27.01
and press the shift key as I drag

15
00:00:27.01 --> 00:00:29.00
in order to create a square.

16
00:00:29.00 --> 00:00:32.00
And now let's give this guy
a yellow fill, let's say,

17
00:00:32.00 --> 00:00:35.06
and I'll change the stroke to
this darker shade of orange.

18
00:00:35.06 --> 00:00:36.06
But it doesn't really matter,

19
00:00:36.06 --> 00:00:39.00
you can obviously go your own way.

20
00:00:39.00 --> 00:00:41.07
Alright, now I'm gonna
switch to the ellipse tool

21
00:00:41.07 --> 00:00:44.08
and I'll go ahead and draw a circle

22
00:00:44.08 --> 00:00:47.04
by pressing and holding
the shift key as I drag.

23
00:00:47.04 --> 00:00:49.07
And let's go ahead and change this guy

24
00:00:49.07 --> 00:00:51.06
to the shade of light blue here.

25
00:00:51.06 --> 00:00:54.04
And I'll change the stroke
to a darker shade of blue

26
00:00:54.04 --> 00:00:56.07
and also thicken up that
stroke to, let's say,

27
00:00:56.07 --> 00:00:59.08
something like 12 points
to make it pretty obvious.

28
00:00:59.08 --> 00:01:00.06
And that way you can see

29
00:01:00.06 --> 00:01:03.03
that blends work with
both fills and strokes.

30
00:01:03.03 --> 00:01:04.05
Alright, now I'll go ahead and switch back

31
00:01:04.05 --> 00:01:05.07
to the black arrow tool,

32
00:01:05.07 --> 00:01:07.06
which you can get by pressing the "v" key.

33
00:01:07.06 --> 00:01:10.06
And I'll shift click on this
square in order to select it.

34
00:01:10.06 --> 00:01:12.06
Now to blend between the two shapes.

35
00:01:12.06 --> 00:01:14.01
You go up to the object menu,

36
00:01:14.01 --> 00:01:17.08
you choose blend, and you
choose the make command,

37
00:01:17.08 --> 00:01:20.03
which has a keyboard
shortcut of "control alt b"

38
00:01:20.03 --> 00:01:22.09
or "command option b" on the Mac.

39
00:01:22.09 --> 00:01:25.01
And we end up with this effect here

40
00:01:25.01 --> 00:01:28.02
so we're essentially creating
a kind of custom gradient

41
00:01:28.02 --> 00:01:30.04
between the two strokes.

42
00:01:30.04 --> 00:01:31.03
And as a result,

43
00:01:31.03 --> 00:01:34.04
the gradient is progressing
from this medium shade of blue

44
00:01:34.04 --> 00:01:38.00
to orange over here in the
upper left hand corner.

45
00:01:38.00 --> 00:01:39.04
But if I were to zoom in,

46
00:01:39.04 --> 00:01:41.02
you can see that the strokes

47
00:01:41.02 --> 00:01:43.01
are growing incrementally thinner

48
00:01:43.01 --> 00:01:45.00
and as a result towards
the end we're seeing gaps

49
00:01:45.00 --> 00:01:47.02
between the strokes that appear yellow

50
00:01:47.02 --> 00:01:49.07
because that's the color
of the square's fill.

51
00:01:49.07 --> 00:01:51.07
Alright, I'm gonna go
ahead and zoom out here.

52
00:01:51.07 --> 00:01:53.02
Now let's say what you wanna do

53
00:01:53.02 --> 00:01:57.06
is change the number of
intervals between the two shapes.

54
00:01:57.06 --> 00:01:59.09
Then you would go up to the object menu,

55
00:01:59.09 --> 00:02:01.04
revisit the blend sub-menu,

56
00:02:01.04 --> 00:02:03.04
and choose blend options,

57
00:02:03.04 --> 00:02:05.04
which will bring up this dialogue box.

58
00:02:05.04 --> 00:02:06.07
Now notice by default,

59
00:02:06.07 --> 00:02:08.07
spacing is set to smooth color.

60
00:02:08.07 --> 00:02:11.02
And so what that does is
it instructs Illustrator

61
00:02:11.02 --> 00:02:13.07
to automatically choose
the number of intervals

62
00:02:13.07 --> 00:02:17.02
it needs in order to
create a smooth gradient.

63
00:02:17.02 --> 00:02:20.00
I want to change that
spacing to specified steps.

64
00:02:20.00 --> 00:02:22.00
You can, however, do distance.

65
00:02:22.00 --> 00:02:24.03
That's going to be the distance
between your intervals,

66
00:02:24.03 --> 00:02:26.03
but if you choose specified steps

67
00:02:26.03 --> 00:02:29.08
that's going to be the number
of intervals inbetween.

68
00:02:29.08 --> 00:02:32.00
And notice that Illustrator's telling me

69
00:02:32.00 --> 00:02:35.04
well right now you're
seeing 240 intervals.

70
00:02:35.04 --> 00:02:36.07
If you want to change that value

71
00:02:36.07 --> 00:02:39.00
presumably you'd want to
turn on the preview checkbox

72
00:02:39.00 --> 00:02:40.04
so that you can see what you're doing.

73
00:02:40.04 --> 00:02:42.09
And I'll go ahead and take
this value down to just two

74
00:02:42.09 --> 00:02:44.06
and press the tab key.

75
00:02:44.06 --> 00:02:48.01
And now you can see our
two intervals right there,

76
00:02:48.01 --> 00:02:51.08
which again Illustrator
refers to as steps.

77
00:02:51.08 --> 00:02:54.00
And so we have a first
object in the background,

78
00:02:54.00 --> 00:02:56.00
we have a second object in the foreground,

79
00:02:56.00 --> 00:02:58.04
and then two intervals inbetween.

80
00:02:58.04 --> 00:03:01.08
I'm gonna take that value
up to six, let's say,

81
00:03:01.08 --> 00:03:05.00
and then press the tab key
so we can see the effect.

82
00:03:05.00 --> 00:03:08.06
And now I'll click okay in
order to accept that change.

83
00:03:08.06 --> 00:03:11.00
Alright, now the great thing
about an object blend like this

84
00:03:11.00 --> 00:03:13.06
is that it's entirely dynamic.

85
00:03:13.06 --> 00:03:16.04
So if I make any changes
to the square or the circle

86
00:03:16.04 --> 00:03:19.06
those changes will be reflected
by the intervals inbetween.

87
00:03:19.06 --> 00:03:21.08
And so now that we've got live shapes,

88
00:03:21.08 --> 00:03:24.04
I'll go ahead and switch
to the ellipse tool

89
00:03:24.04 --> 00:03:26.05
so that I can see the specialized widgets.

90
00:03:26.05 --> 00:03:30.02
And notice now that I can drag
the center of this ellipse,

91
00:03:30.02 --> 00:03:32.06
assuming that you're seeing
your widgets on screen,

92
00:03:32.06 --> 00:03:35.00
and the ellipse will move
to a different location

93
00:03:35.00 --> 00:03:36.07
and all the intervals inbetween

94
00:03:36.07 --> 00:03:39.07
will move to a different location as well.

95
00:03:39.07 --> 00:03:42.04
The other option is to create a pie

96
00:03:42.04 --> 00:03:44.05
by dragging this guy right here

97
00:03:44.05 --> 00:03:46.05
and I'll go ahead and drag it all the way

98
00:03:46.05 --> 00:03:47.04
over to this location

99
00:03:47.04 --> 00:03:50.04
and I'll drag this guy over to
the right hand side as well.

100
00:03:50.04 --> 00:03:51.05
So that we can see

101
00:03:51.05 --> 00:03:54.04
the evolution of a square
turning into a pac-man.

102
00:03:54.04 --> 00:03:56.00
Alright, I'll go ahead
and drag this guy up

103
00:03:56.00 --> 00:03:57.08
just a little bit and
the same's gonna happen

104
00:03:57.08 --> 00:04:00.01
if I move over to the square

105
00:04:00.01 --> 00:04:03.03
and adjust its round
corner, which is like so.

106
00:04:03.03 --> 00:04:04.07
And at that point we're gonna start to see

107
00:04:04.07 --> 00:04:07.09
some rounding at the top
of these initial shapes.

108
00:04:07.09 --> 00:04:09.00
And incidentally, just in case

109
00:04:09.00 --> 00:04:10.09
you turned off your live shape widgets,

110
00:04:10.09 --> 00:04:13.03
just go ahead and switch
over to the white arrow tool,

111
00:04:13.03 --> 00:04:15.01
which you can get by pressing the "a" key.

112
00:04:15.01 --> 00:04:16.04
And then just go ahead

113
00:04:16.04 --> 00:04:18.05
and click off the shapes to deselect them

114
00:04:18.05 --> 00:04:21.06
and then click inside one
of the shapes to select it.

115
00:04:21.06 --> 00:04:25.01
For example, I've clicked
inside my pie-shaped circle

116
00:04:25.01 --> 00:04:26.04
and then you would go ahead and select

117
00:04:26.04 --> 00:04:29.09
either the rectangle
tool or the ellipse tool,

118
00:04:29.09 --> 00:04:32.05
in which point you can
see the shape widgets icon

119
00:04:32.05 --> 00:04:34.00
up here in the control panel,

120
00:04:34.00 --> 00:04:37.00
and you can either turn it off
to make the widgets go away

121
00:04:37.00 --> 00:04:40.08
or you can turn it on to
make those widgets come back.

122
00:04:40.08 --> 00:04:42.01
Alright, and the other thing I can do is

123
00:04:42.01 --> 00:04:44.00
switch back to the white arrow tool

124
00:04:44.00 --> 00:04:45.09
and drag the shape around

125
00:04:45.09 --> 00:04:47.02
and that's gonna cause the blend

126
00:04:47.02 --> 00:04:49.03
to update automatically as well.

127
00:04:49.03 --> 00:04:51.04
And last, I just want you to notice

128
00:04:51.04 --> 00:04:52.04
in case you haven't already,

129
00:04:52.04 --> 00:04:54.09
that each one of the intervals
is gradually progressing

130
00:04:54.09 --> 00:04:57.01
in terms of fill and stroke color

131
00:04:57.01 --> 00:04:58.07
as well as line weight.

132
00:04:58.07 --> 00:05:00.06
And so with the circle selected,

133
00:05:00.06 --> 00:05:02.06
if I was to take that line weight up to,

134
00:05:02.06 --> 00:05:05.04
let's say, 24 points
and press the enter key

135
00:05:05.04 --> 00:05:06.08
or the return key on a Mac,

136
00:05:06.08 --> 00:05:10.08
that's going to affect all the
intervals inbetween as well.

137
00:05:10.08 --> 00:05:11.09
And so that's how you create

138
00:05:11.09 --> 00:05:14.03
an object blend between two shapes

139
00:05:14.03 --> 00:05:15.08
and have an update dynamically

140
00:05:15.08 --> 00:05:17.06
in response to any modifications

141
00:05:17.06 --> 00:05:20.09
you might make here inside Illustrator.
