1
00:00:10,000 --> 00:00:17,000
So another modify command we have available to us is the array tool and the array tool.

2
00:00:18,000 --> 00:00:24,000
It's good for when you want to create multiple copies of of something in a particular pattern.

3
00:00:25,000 --> 00:00:28,000
So I'm going to just draw out something here.

4
00:00:28,000 --> 00:00:32,000
This is going to be a floor plan and it's going to be

5
00:00:34,000 --> 00:00:35,000
50mm.

6
00:00:37,000 --> 00:00:44,000
Let's just make it 50mm by 50m, side by 50m, just to keep things easy.

7
00:00:44,000 --> 00:00:46,000
And up here.

8
00:00:50,000 --> 00:00:51,000
I'm going to go.

9
00:00:52,000 --> 00:00:53,000
I'm going to draw a column.

10
00:00:54,000 --> 00:00:54,000
Okay.

11
00:00:55,000 --> 00:01:01,000
And again, to make it easy, it's 500mm by 500mm.

12
00:01:01,000 --> 00:01:03,000
So that's a column in the corner.

13
00:01:03,000 --> 00:01:05,000
Now, I want to space these columns out.

14
00:01:05,000 --> 00:01:10,000
I want columns in a kind of a grid pattern all the way over this building.

15
00:01:11,000 --> 00:01:14,000
So you could copy and.

16
00:01:14,000 --> 00:01:19,000
And let's say there are five meters apart.

17
00:01:19,000 --> 00:01:23,000
I could copy it and kind of go five metres and do it that way.

18
00:01:23,000 --> 00:01:26,000
And then it's a long winded way of doing it.

19
00:01:26,000 --> 00:01:31,000
And as always, without covers, usually easy ways of doing things like that.

20
00:01:31,000 --> 00:01:36,000
So the easy way in this case is the array command.

21
00:01:38,000 --> 00:01:44,000
So if we click on that, we now get asked to select the objects and I'm going to select that one and

22
00:01:44,000 --> 00:01:46,000
right click and now it comes up.

23
00:01:47,000 --> 00:01:51,000
With all these options and a new toolbar and a kind of visual.

24
00:01:54,000 --> 00:01:57,000
And display of what's going on here.

25
00:01:57,000 --> 00:02:03,000
So already it's done four columns and three rows.

26
00:02:03,000 --> 00:02:04,000
Okay, So rows are going up that way.

27
00:02:04,000 --> 00:02:05,000
Columns are this way.

28
00:02:06,000 --> 00:02:10,000
And you can see that up here, it's done four columns and three rows.

29
00:02:10,000 --> 00:02:14,000
And if I was to change this to six columns and.

30
00:02:15,000 --> 00:02:17,000
It updates here to six.

31
00:02:19,000 --> 00:02:20,000
The spacing.

32
00:02:22,000 --> 00:02:23,000
It's got.

33
00:02:23,000 --> 00:02:27,000
So the space between them is 750.

34
00:02:27,000 --> 00:02:30,000
Now, bear in mind that's from the same similar points.

35
00:02:30,000 --> 00:02:37,000
It's not when it says space between it doesn't mean this space, it would mean the space from.

36
00:02:37,000 --> 00:02:42,000
But top left corner of the square to that top left corner of the square.

37
00:02:42,000 --> 00:02:45,000
And you can see it's 500, which we know plus 250.

38
00:02:45,000 --> 00:02:52,000
So it's it's the distance between similar points and then it's got the total distance, which would

39
00:02:52,000 --> 00:02:54,000
be the distance from here all the way along.

40
00:02:55,000 --> 00:03:00,000
Now, we can also drag it out here and do it with the arrows.

41
00:03:02,000 --> 00:03:03,000
And we could do it that way.

42
00:03:03,000 --> 00:03:10,000
Maybe we knew the distance between was five meters and same that way.

43
00:03:12,000 --> 00:03:13,000
Now it's going.

44
00:03:13,000 --> 00:03:16,000
Now we can just use these arrows.

45
00:03:21,000 --> 00:03:21,000
Okay.

46
00:03:21,000 --> 00:03:26,000
And it's not going to quite reach the end because it's 50 divided by five.

47
00:03:26,000 --> 00:03:28,000
So we could move this.

48
00:03:28,000 --> 00:03:31,000
Maybe I'm just going to do it by eye.

49
00:03:33,000 --> 00:03:35,000
Maybe it was something like that.

50
00:03:36,000 --> 00:03:36,000
Okay.

51
00:03:36,000 --> 00:03:37,000
And that's our columns.

52
00:03:38,000 --> 00:03:39,000
And we can set distances.

53
00:03:39,000 --> 00:03:40,000
Maybe it's changed.

54
00:03:40,000 --> 00:03:44,000
So we're actually four meters separation.

55
00:03:51,000 --> 00:03:54,000
And that means we get an extra couple of rows.

56
00:03:54,000 --> 00:03:57,000
Extra couple of columns and rows.

57
00:03:57,000 --> 00:04:07,000
So it's so easy to create multiple instances of the same object and you can edit arrays.

58
00:04:07,000 --> 00:04:13,000
Once you've done an array, if you click on it, you get options to edit it to replace items and all

59
00:04:13,000 --> 00:04:15,000
that kind of thing.

60
00:04:16,000 --> 00:04:18,000
So arrays can be really powerful.

61
00:04:18,000 --> 00:04:24,000
They can save you loads of time if you're doing something like anytime you're doing things uniformly

62
00:04:24,000 --> 00:04:27,000
spaced like that, you want to be thinking of arrays.

63
00:04:28,000 --> 00:04:30,000
But maybe.

64
00:04:31,000 --> 00:04:35,000
Maybe I add a circle and.

65
00:04:38,000 --> 00:04:39,000
Something like that.

66
00:04:39,000 --> 00:04:46,000
And I wanted to put these around this circle here.

67
00:04:47,000 --> 00:04:48,000
It's the same thing.

68
00:04:48,000 --> 00:04:49,000
It's still an array.

69
00:04:49,000 --> 00:04:52,000
So with arrays, there's there's three types.

70
00:04:53,000 --> 00:04:56,000
There's rectangular path array and polar array.

71
00:04:56,000 --> 00:04:58,000
And the next one we'll look at is polar array.

72
00:04:58,000 --> 00:05:00,000
Okay, so we've looked at rectangular array.

73
00:05:01,000 --> 00:05:04,000
So if you pull that down and go to polar array.

74
00:05:05,000 --> 00:05:09,000
Now, this is when you want things in degrees rather than rows and columns.

75
00:05:09,000 --> 00:05:11,000
And again, it will say select objects.

76
00:05:11,000 --> 00:05:13,000
So I want that one right click.

77
00:05:13,000 --> 00:05:15,000
And now it needs a center point.

78
00:05:15,000 --> 00:05:18,000
So where is the rotation around?

79
00:05:18,000 --> 00:05:20,000
And it's going to be the center of that circle.

80
00:05:20,000 --> 00:05:24,000
And now again, you'll see it's already done a visual kind of display.

81
00:05:25,000 --> 00:05:28,000
It's giving it a guess, but I can change that.

82
00:05:28,000 --> 00:05:29,000
So.

83
00:05:30,000 --> 00:05:35,000
We have a number of items which in this case it's given us six items with 60.

84
00:05:35,000 --> 00:05:36,000
This is in degrees now.

85
00:05:36,000 --> 00:05:41,000
So 60 degrees between each item and it's filling the whole 360 degrees.

86
00:05:42,000 --> 00:05:44,000
Well, maybe I wanted many.

87
00:05:44,000 --> 00:05:46,000
Maybe I wanted like a clock face.

88
00:05:46,000 --> 00:05:48,000
I wanted 12 items.

89
00:05:48,000 --> 00:05:48,000
Okay.

90
00:05:51,000 --> 00:05:52,000
Now it's going to update.

91
00:05:52,000 --> 00:05:59,000
It's going to change the the angle between because obviously, if 360 divided by 12 is 30.

92
00:05:59,000 --> 00:06:01,000
So now we've got our items there.

93
00:06:01,000 --> 00:06:04,000
We don't have to go over three full, 360.

94
00:06:04,000 --> 00:06:05,000
We could go just 180.

95
00:06:07,000 --> 00:06:09,000
But something's always got to change.

96
00:06:09,000 --> 00:06:11,000
One of these has always got to change.

97
00:06:11,000 --> 00:06:17,000
If you go down to 180 and you keep 12 items, it's going to now be 16 degrees between the two.

98
00:06:17,000 --> 00:06:23,000
Or you could keep it as six items and now it'll go back and it'll you see, you can fiddle around with

99
00:06:23,000 --> 00:06:23,000
these.

100
00:06:23,000 --> 00:06:24,000
Okay.

101
00:06:28,000 --> 00:06:30,000
And you can change what you want.

102
00:06:32,000 --> 00:06:33,000
You can also have rows here.

103
00:06:34,000 --> 00:06:39,000
So maybe you wanted six rows going out there.

104
00:06:39,000 --> 00:06:40,000
You can do that kind of thing.

105
00:06:40,000 --> 00:06:42,000
Let's put that back to 360.

106
00:06:43,000 --> 00:06:46,000
And so you can do these kind of patterns here and you can have levels.

107
00:06:46,000 --> 00:06:50,000
You can change things, so you can replace items and reset.

108
00:06:50,000 --> 00:06:55,000
Again, it's fun to just play around with and you work out what exactly how you can use it.

109
00:06:55,000 --> 00:06:58,000
But that's the basic method behind it.

110
00:06:59,000 --> 00:07:03,000
And you can use these arrows to change settings as well.

111
00:07:03,000 --> 00:07:07,000
So you can actually snap to points on existing drawings, for instance.

112
00:07:07,000 --> 00:07:12,000
So that's a polar array and this is a rectangular array.

113
00:07:12,000 --> 00:07:14,000
Let me just make that smaller.

114
00:07:17,000 --> 00:07:19,000
Now we have a type of array.

115
00:07:19,000 --> 00:07:20,000
I'm going to do a polyline.

116
00:07:23,000 --> 00:07:24,000
I'd imagine this was a fence.

117
00:07:25,000 --> 00:07:31,000
Maybe it goes up and it's got, let's say, an arc and then a line.

118
00:07:32,000 --> 00:07:41,000
Maybe you've got for some reason you've got a line like that and you want to put something along it.

119
00:07:41,000 --> 00:07:43,000
So this is a fence.

120
00:07:43,000 --> 00:07:46,000
It's a weird looking fence, but it's a fence and this is a fence post.

121
00:07:46,000 --> 00:07:49,000
And I want fence posts all the way along this line.

122
00:07:50,000 --> 00:07:52,000
Then we use this path array.

123
00:07:53,000 --> 00:07:57,000
So we click that and again we select the objects, right click.

124
00:07:57,000 --> 00:08:03,000
And now we select the path and we click that and same thing comes up here, gives us a guess about what

125
00:08:03,000 --> 00:08:04,000
we want.

126
00:08:06,000 --> 00:08:10,000
And usually I'd say in this case you would have something like a distance between.

127
00:08:11,000 --> 00:08:16,000
So maybe you've got ten meters between.

128
00:08:16,000 --> 00:08:22,000
And so you can set out these fence posts along this line and you could change that.

129
00:08:22,000 --> 00:08:26,000
So maybe you just knew the total number of items or the total number.

130
00:08:29,000 --> 00:08:32,000
Again, you can have rows, so you can do that kind of thing.

131
00:08:32,000 --> 00:08:37,000
Levels, which is more a 3D thing going up in height and associative.

132
00:08:37,000 --> 00:08:41,000
You can change base points, you can change directions measurement, you can align them.

133
00:08:41,000 --> 00:08:43,000
So in this case, it was a circle.

134
00:08:45,000 --> 00:08:46,000
If I can do that.

135
00:08:49,000 --> 00:08:56,000
Suppose we now draw drawn a rectangle and I'll do a suppose I've drawn a rectangle.

136
00:08:57,000 --> 00:08:58,000
Okay.

137
00:08:59,000 --> 00:09:03,000
And I'm just going to put that rectangle there.

138
00:09:04,000 --> 00:09:06,000
Suppose I've done a rectangle along here.

139
00:09:06,000 --> 00:09:07,000
I do that array again.

140
00:09:07,000 --> 00:09:08,000
I'll select the object.

141
00:09:10,000 --> 00:09:11,000
Select the path.

142
00:09:12,000 --> 00:09:20,000
Now you can see what happens is the rectangle rotates and it follows a curve and the angle of a line.

143
00:09:20,000 --> 00:09:23,000
And that's because it has this line items on.

144
00:09:23,000 --> 00:09:29,000
If that was turned off now you'll see the rectangle remains in its same position all the way around,

145
00:09:29,000 --> 00:09:31,000
so there's different options you can use.

146
00:09:31,000 --> 00:09:33,000
Again, play about with it.

147
00:09:33,000 --> 00:09:35,000
There's times when this comes in very handy.

148
00:09:36,000 --> 00:09:39,000
It's another of those commands that you don't use all the time.

149
00:09:39,000 --> 00:09:42,000
It depends what you're doing, but I don't use it all the time.

150
00:09:42,000 --> 00:09:44,000
But every now and then when I use it, I really do need it.

151
00:09:44,000 --> 00:09:48,000
You can see it's a massive time saver and that's arrays.

152
00:09:48,000 --> 00:09:58,000
So yeah, have a play about with them and fairly self-explanatory the old versions of AutoCAD, it doesn't

153
00:09:58,000 --> 00:10:03,000
have as much of a kind of previewing and dragging with grips, so it was harder to see what was going

154
00:10:03,000 --> 00:10:03,000
on.

155
00:10:03,000 --> 00:10:09,000
Now with these new versions, the way it gives you that preview straight away and lets you drag things

156
00:10:09,000 --> 00:10:12,000
around, it makes it so much easier to visualize.

157
00:10:12,000 --> 00:10:13,000
But that's arrays.
