1
00:00:00.06 --> 00:00:01.07
- [Instructor] In this
movie, we'll duplicate

2
00:00:01.07 --> 00:00:03.08
the two lines that we've drawn so far,

3
00:00:03.08 --> 00:00:05.07
in order to create these ridges

4
00:00:05.07 --> 00:00:08.06
along what will ultimately
be the top of the factory.

5
00:00:08.06 --> 00:00:09.07
And along the way,

6
00:00:09.07 --> 00:00:10.07
I'll show you a few different things

7
00:00:10.07 --> 00:00:13.07
that you can do with the
black and white arrow tools.

8
00:00:13.07 --> 00:00:15.08
So I'll go ahead and
switch over to these lines.

9
00:00:15.08 --> 00:00:17.04
You can see that they're both selected,

10
00:00:17.04 --> 00:00:18.06
but if you're working along

11
00:00:18.06 --> 00:00:20.02
and they're not selected for you,

12
00:00:20.02 --> 00:00:22.05
then you can just partially marquee them

13
00:00:22.05 --> 00:00:24.00
with the black arrow tool.

14
00:00:24.00 --> 00:00:25.04
And because I'm working
with the black arrow,

15
00:00:25.04 --> 00:00:29.01
no matter what, I'm going to
select the entire objects.

16
00:00:29.01 --> 00:00:31.03
Now what I want to do is move these lines,

17
00:00:31.03 --> 00:00:34.03
and you can do that by
dragging on either one of them,

18
00:00:34.03 --> 00:00:37.01
like so, and so of course
if you just drag them

19
00:00:37.01 --> 00:00:39.01
and then drop them into a new place,

20
00:00:39.01 --> 00:00:40.05
that's where they're going to land.

21
00:00:40.05 --> 00:00:42.00
There's other ways to work, however.

22
00:00:42.00 --> 00:00:45.04
Let's say for example, that you
want to duplicate the paths.

23
00:00:45.04 --> 00:00:48.05
In that case, instead of
just dragging and dropping,

24
00:00:48.05 --> 00:00:49.07
you would drag them,

25
00:00:49.07 --> 00:00:52.01
and then you would press
and hold the Alt key,

26
00:00:52.01 --> 00:00:53.07
or the Option key on the Mac,

27
00:00:53.07 --> 00:00:57.03
and notice at that point, I
get a double arrowhead cursor,

28
00:00:57.03 --> 00:01:00.01
which tells me that I'm
going to create a duplicate.

29
00:01:00.01 --> 00:01:02.06
So again, you go ahead
and press the Alt key

30
00:01:02.06 --> 00:01:05.09
or the Option key on the Mac
after you begin dragging,

31
00:01:05.09 --> 00:01:08.06
and then hold it until after you release,

32
00:01:08.06 --> 00:01:12.04
in order to duplicate those
paths' outlines, like so.

33
00:01:12.04 --> 00:01:14.00
I want a little more control, though,

34
00:01:14.00 --> 00:01:17.03
I want to go ahead and just
move these lines horizontally,

35
00:01:17.03 --> 00:01:19.08
so I will press Control-Z,
or Command-Z on the Mac,

36
00:01:19.08 --> 00:01:21.09
to once again undo that move.

37
00:01:21.09 --> 00:01:24.03
And then this time, as I drag,

38
00:01:24.03 --> 00:01:26.03
I'll press and hold the Shift key,

39
00:01:26.03 --> 00:01:29.00
which will constrain the angle of my drag

40
00:01:29.00 --> 00:01:32.00
to some multiple of 45 degrees.

41
00:01:32.00 --> 00:01:35.08
So that way, I can drag directly
up, I can drag diagonally,

42
00:01:35.08 --> 00:01:39.02
or I can drag horizontally, like, so.

43
00:01:39.02 --> 00:01:40.04
But what I really want to do

44
00:01:40.04 --> 00:01:42.07
is duplicate these lines horizontally,

45
00:01:42.07 --> 00:01:44.08
and I want them to snap into alignment.

46
00:01:44.08 --> 00:01:48.00
So I will once again press
Control-Z, Command-Z on a Mac,

47
00:01:48.00 --> 00:01:51.04
and this time, I will drag by
this anchor point right there,

48
00:01:51.04 --> 00:01:52.03
so again,

49
00:01:52.03 --> 00:01:55.01
your bounding box needs to
be off for this to work,

50
00:01:55.01 --> 00:01:56.09
otherwise, you're going
to scale your lines,

51
00:01:56.09 --> 00:01:58.02
which is not what we want.

52
00:01:58.02 --> 00:02:01.02
So go ahead and drag by
this lower anchor point,

53
00:02:01.02 --> 00:02:04.03
while pressing the Shift
key, until you see a snap,

54
00:02:04.03 --> 00:02:05.09
right there at that location,

55
00:02:05.09 --> 00:02:08.05
as indicated by that
white arrowhead cursor,

56
00:02:08.05 --> 00:02:11.01
and then you also want
to press the Alt key,

57
00:02:11.01 --> 00:02:12.09
or the Option key on the Mac,

58
00:02:12.09 --> 00:02:15.05
at which point you're going to
get a double white arrowhead,

59
00:02:15.05 --> 00:02:18.09
telling you that you're going
to snap a duplicate into place.

60
00:02:18.09 --> 00:02:20.07
So again, I've got the Shift and Alt keys

61
00:02:20.07 --> 00:02:22.02
down here on the PC,

62
00:02:22.02 --> 00:02:24.02
that would be Shift and Option on the Mac.

63
00:02:24.02 --> 00:02:27.01
Hold those keys down,
release your mouse button,

64
00:02:27.01 --> 00:02:29.02
and then release the keys.

65
00:02:29.02 --> 00:02:31.07
All right, now I want to
create yet another duplicate,

66
00:02:31.07 --> 00:02:34.06
and so, I could of course
replay that operation,

67
00:02:34.06 --> 00:02:36.03
but there's an easier way to work,

68
00:02:36.03 --> 00:02:38.04
and that's to go up to the Object menu,

69
00:02:38.04 --> 00:02:41.07
choose Transform, and then
choose this very first command

70
00:02:41.07 --> 00:02:44.08
at the top of the
sub-menu, Transform Again.

71
00:02:44.08 --> 00:02:47.02
Or, better yet, use the keyboard shortcut

72
00:02:47.02 --> 00:02:49.00
that makes a heck of a lot more sense,

73
00:02:49.00 --> 00:02:52.03
which is Control-D, or
Command-D on the Mac,

74
00:02:52.03 --> 00:02:54.03
the D being for duplicate.

75
00:02:54.03 --> 00:02:55.02
And so essentially,

76
00:02:55.02 --> 00:02:57.06
you're going to replay
your last duplication.

77
00:02:57.06 --> 00:03:01.04
Again, Control-D, or
Command-D on the Mac will do.

78
00:03:01.04 --> 00:03:03.02
All right, now I want
to draw a vertical line

79
00:03:03.02 --> 00:03:05.07
going downward from this point right here.

80
00:03:05.07 --> 00:03:08.00
So I'll go ahead and switch
to my line segment tool,

81
00:03:08.00 --> 00:03:09.03
which again, you can get

82
00:03:09.03 --> 00:03:12.00
by pressing the Backslash key if you like.

83
00:03:12.00 --> 00:03:14.05
And I want the line to start
at this point right there,

84
00:03:14.05 --> 00:03:17.06
but if you get this behavior
when you drag the line,

85
00:03:17.06 --> 00:03:20.05
that is to say you end up
moving that selected point,

86
00:03:20.05 --> 00:03:22.05
then just undo that movement,

87
00:03:22.05 --> 00:03:24.00
and then go up to the Select menu,

88
00:03:24.00 --> 00:03:26.03
and choose Deselect once again,

89
00:03:26.03 --> 00:03:29.09
or press Control-Shift-A or
Command-Shift-A on the Mac.

90
00:03:29.09 --> 00:03:33.03
And now, you should be able
to drag a line down, like so.

91
00:03:33.03 --> 00:03:35.04
I want this line to be
absolutely vertical,

92
00:03:35.04 --> 00:03:38.06
so I'm going to press and
hold the Shift key as I drag.

93
00:03:38.06 --> 00:03:40.09
And I'm looking for a distance value

94
00:03:40.09 --> 00:03:43.04
of about 300 points, let's say,

95
00:03:43.04 --> 00:03:45.06
so I've got a devalue of 300 points

96
00:03:45.06 --> 00:03:49.00
in that heads-up display, I
have an angle of 270 degrees,

97
00:03:49.00 --> 00:03:52.00
because I'm dragging down with
the Shift key down as well,

98
00:03:52.00 --> 00:03:54.02
and then, I'll go ahead and
release the mouse button,

99
00:03:54.02 --> 00:03:57.01
and then release the Shift key.

100
00:03:57.01 --> 00:03:58.04
All right, now what we want to do

101
00:03:58.04 --> 00:04:01.00
is extend this line right there,

102
00:04:01.00 --> 00:04:04.03
so it aligns to the bottom
of the line we just drew,

103
00:04:04.03 --> 00:04:07.04
and you can do that by switching
to the white arrow tool,

104
00:04:07.04 --> 00:04:09.02
which you can get either by selecting

105
00:04:09.02 --> 00:04:12.02
the second arrow up here
at the top of the toolbox,

106
00:04:12.02 --> 00:04:14.00
and don't worry if you don't see a tail

107
00:04:14.00 --> 00:04:15.08
on your white arrow icon,

108
00:04:15.08 --> 00:04:18.08
the tool still works
the same as it ever has.

109
00:04:18.08 --> 00:04:21.08
Or you can just press
the A key, for arrow.

110
00:04:21.08 --> 00:04:23.01
Then, go ahead and click

111
00:04:23.01 --> 00:04:25.03
on this so-called anchor
point right there,

112
00:04:25.03 --> 00:04:28.08
which is located at the bottom
of this right hand line.

113
00:04:28.08 --> 00:04:31.04
And notice, if you will,
if you look closely,

114
00:04:31.04 --> 00:04:34.02
that the selected point is now filled in,

115
00:04:34.02 --> 00:04:37.03
it happens to be red, because
we're working on a red layer,

116
00:04:37.03 --> 00:04:39.02
and the top point is hollow,

117
00:04:39.02 --> 00:04:41.04
indicating that it is not selected.

118
00:04:41.04 --> 00:04:44.06
So now, if I go ahead and
drag this point down like so,

119
00:04:44.06 --> 00:04:45.07
and I press the Shift key,

120
00:04:45.07 --> 00:04:47.02
just to make sure that I'm constraining

121
00:04:47.02 --> 00:04:50.05
the angle of my drag to exactly vertical,

122
00:04:50.05 --> 00:04:52.02
if you have smart guides turned on,

123
00:04:52.02 --> 00:04:54.05
you're going to see
these intersecting lines

124
00:04:54.05 --> 00:04:56.09
that are telling you
that you have a match.

125
00:04:56.09 --> 00:04:59.01
So you want to make sure
you're seeing that bottom,

126
00:04:59.01 --> 00:05:00.07
in my case, pink line.

127
00:05:00.07 --> 00:05:01.09
It might be green as well,

128
00:05:01.09 --> 00:05:04.05
depending on what version of
the program you're working on.

129
00:05:04.05 --> 00:05:06.06
But you want to see that intersection,

130
00:05:06.06 --> 00:05:08.07
at which point you can
go ahead and release,

131
00:05:08.07 --> 00:05:12.06
knowing that these two points
are absolutely aligned.

132
00:05:12.06 --> 00:05:13.09
All right, finally what I want to do

133
00:05:13.09 --> 00:05:16.00
is move these ridges downward,

134
00:05:16.00 --> 00:05:18.02
and I'm going to do so by marqueeing

135
00:05:18.02 --> 00:05:20.08
all of these top anchor points.

136
00:05:20.08 --> 00:05:22.07
So notice, whenever you drag

137
00:05:22.07 --> 00:05:24.08
in an empty area of your document,

138
00:05:24.08 --> 00:05:26.09
you're going to create a dotted marquee,

139
00:05:26.09 --> 00:05:29.08
and then anything that
falls inside that marquee

140
00:05:29.08 --> 00:05:32.04
is going to become
selected, because after all,

141
00:05:32.04 --> 00:05:33.08
unlike the black arrow tool,

142
00:05:33.08 --> 00:05:36.02
which always selects entire path outlines,

143
00:05:36.02 --> 00:05:38.04
the white arrow tool is going to allow you

144
00:05:38.04 --> 00:05:42.04
just to select those points
that fall inside the marquee.

145
00:05:42.04 --> 00:05:44.01
So make sure that you draw the marquee

146
00:05:44.01 --> 00:05:46.09
around all the top points, like so.

147
00:05:46.09 --> 00:05:50.05
And then, go ahead and drag
any one of them downward,

148
00:05:50.05 --> 00:05:52.00
while pressing the Shift key,

149
00:05:52.00 --> 00:05:53.09
just to make sure that
the angle of your drag

150
00:05:53.09 --> 00:05:55.05
is exactly vertical,

151
00:05:55.05 --> 00:05:57.05
until your cursor snaps into alignment

152
00:05:57.05 --> 00:05:59.04
with that horizontal guideline,

153
00:05:59.04 --> 00:06:00.07
and you'll know you have a snap,

154
00:06:00.07 --> 00:06:02.07
because for one thing, you can feel it,

155
00:06:02.07 --> 00:06:03.09
and then for another,

156
00:06:03.09 --> 00:06:06.03
your cursor will change
to a white arrowhead.

157
00:06:06.03 --> 00:06:08.07
At which point, go ahead and
release the mouse button,

158
00:06:08.07 --> 00:06:11.06
and then, release the Shift key.

159
00:06:11.06 --> 00:06:14.05
And that is how you
both move and duplicate

160
00:06:14.05 --> 00:06:18.06
entire path outlines, as well
as independent anchor points,

161
00:06:18.06 --> 00:06:20.06
here inside Illustrator.
