1
00:00:09,000 --> 00:00:12,000
So next up, we're going to look at hatching.

2
00:00:12,000 --> 00:00:20,000
Hatching can be well, it can look complex, but there's some basic principles to stick to.

3
00:00:20,000 --> 00:00:22,000
And that covers all hatching, really.

4
00:00:22,000 --> 00:00:25,000
So we're going to create a basic rectangle.

5
00:00:25,000 --> 00:00:26,000
Okay.

6
00:00:26,000 --> 00:00:27,000
And I'm just going to do it by eye.

7
00:00:28,000 --> 00:00:30,000
Let's say something like that.

8
00:00:30,000 --> 00:00:30,000
Okay.

9
00:00:30,000 --> 00:00:31,000
And.

10
00:00:32,000 --> 00:00:34,000
And to create a hatch.

11
00:00:34,000 --> 00:00:37,000
We have this icon here under the draw command.

12
00:00:37,000 --> 00:00:38,000
Okay.

13
00:00:39,000 --> 00:00:42,000
And we have some some different options underneath.

14
00:00:42,000 --> 00:00:43,000
For now, we're just going to concentrate on Hatch.

15
00:00:43,000 --> 00:00:46,000
This is the one you'll use most, just this hatch command.

16
00:00:46,000 --> 00:00:49,000
And it can also be done by just typing h return.

17
00:00:49,000 --> 00:00:53,000
That's the kind of shortcut key but that's the icon there.

18
00:00:53,000 --> 00:00:54,000
Hatch Okay.

19
00:00:54,000 --> 00:01:02,000
And now you get a new toolbar with a whole load of options, but they're pretty basic, first of all.

20
00:01:02,000 --> 00:01:12,000
There's these two options to choose a hatched area and you'll use, depending on what your object looks

21
00:01:12,000 --> 00:01:18,000
like and how crowded your drawing is, you might use one or the other, but we'll look at those later.

22
00:01:18,000 --> 00:01:20,000
For now, I'm going to just select.

23
00:01:21,000 --> 00:01:22,000
I'm just going to choose a select command.

24
00:01:22,000 --> 00:01:23,000
Okay.

25
00:01:26,000 --> 00:01:28,000
So here we have a boundary.

26
00:01:28,000 --> 00:01:29,000
So it's a clear boundary.

27
00:01:29,000 --> 00:01:32,000
It's a rectangle, which means it's closed.

28
00:01:32,000 --> 00:01:32,000
Okay.

29
00:01:33,000 --> 00:01:34,000
There's no openings in it.

30
00:01:34,000 --> 00:01:35,000
It's a closed line.

31
00:01:36,000 --> 00:01:39,000
So we we can automatically fill this.

32
00:01:39,000 --> 00:01:42,000
If you imagine it's a bit like the paint bucket tool.

33
00:01:42,000 --> 00:01:48,000
If you've ever used any of things like Photoshop and things, you want to fill this with a pattern or

34
00:01:48,000 --> 00:01:49,000
a color or both.

35
00:01:49,000 --> 00:01:50,000
Okay.

36
00:01:50,000 --> 00:01:56,000
If there's any gaps in this line, then that fill is going to leak out and you're going to get some

37
00:01:56,000 --> 00:02:00,000
if it's going to fail or you're going to get some kind of crazy behavior.

38
00:02:00,000 --> 00:02:04,000
So you want to be always using these closed lines with a hatch.

39
00:02:04,000 --> 00:02:08,000
And we'll look at again, we'll look a bit more about that later.

40
00:02:08,000 --> 00:02:11,000
But for now, let's just create a basic hatch.

41
00:02:11,000 --> 00:02:16,000
So we've got our select command, which means select an object to hatch.

42
00:02:18,000 --> 00:02:19,000
A man.

43
00:02:19,000 --> 00:02:21,000
We can choose our pattern.

44
00:02:21,000 --> 00:02:23,000
So.

45
00:02:26,000 --> 00:02:31,000
You can click this little button here to bring it out a bit more, give you a better view.

46
00:02:31,000 --> 00:02:39,000
AutoCAD comes with all these kind of standard hatches which go back to some of them, the old hand-drawn

47
00:02:39,000 --> 00:02:44,000
days where different things would represent different types of brickwork and blockwork and that kind

48
00:02:44,000 --> 00:02:44,000
of thing.

49
00:02:45,000 --> 00:02:47,000
So it includes all those basic hatches.

50
00:02:47,000 --> 00:02:50,000
And generally these are good enough to get you through most things.

51
00:02:52,000 --> 00:02:55,000
You can have concrete, you can have brick, all that kind of thing.

52
00:02:55,000 --> 00:03:01,000
So if I wanted to make this into just some diagonal lines, we'll choose that one.

53
00:03:01,000 --> 00:03:02,000
Okay.

54
00:03:03,000 --> 00:03:04,000
And we're already on select.

55
00:03:04,000 --> 00:03:09,000
So now I select that object and you'll see if we zoom in, we get all these diagonal lines.

56
00:03:09,000 --> 00:03:10,000
Okay.

57
00:03:12,000 --> 00:03:18,000
The thing is, I know looking at this, it's just going to look like a kind of solid hatch because the

58
00:03:18,000 --> 00:03:20,000
lines are too close together.

59
00:03:20,000 --> 00:03:22,000
So it's no good at the moment.

60
00:03:22,000 --> 00:03:26,000
And that's where our properties panel comes in, which is the next kind of box.

61
00:03:26,000 --> 00:03:27,000
Okay.

62
00:03:27,000 --> 00:03:28,000
And here we have different things.

63
00:03:28,000 --> 00:03:31,000
We've got pattern which will change between this kind of pattern.

64
00:03:31,000 --> 00:03:36,000
So where it says pattern, it means we're using an actual design like this, a diagonal lines.

65
00:03:36,000 --> 00:03:41,000
We could change it to a solid hatch, which is just a full, solid color.

66
00:03:42,000 --> 00:03:49,000
Which is it's also the pattern, but you can change it here or a gradient, which is basically a it

67
00:03:49,000 --> 00:03:50,000
will change.

68
00:03:50,000 --> 00:03:53,000
It will blend gradually from one color to the other.

69
00:03:53,000 --> 00:03:54,000
And you've got different types of gradients.

70
00:03:54,000 --> 00:03:57,000
You can have it going back to the same color.

71
00:03:57,000 --> 00:03:59,000
So you've got these different gradients here.

72
00:03:59,000 --> 00:04:00,000
You could have circular ones.

73
00:04:02,000 --> 00:04:03,000
Okay.

74
00:04:03,000 --> 00:04:04,000
The.

75
00:04:05,000 --> 00:04:07,000
But we're going to stick with pattern at the moment.

76
00:04:07,000 --> 00:04:11,000
And this pull down, really, that's the three main types of hatch.

77
00:04:11,000 --> 00:04:13,000
So you've got solid hatches which are just solid.

78
00:04:13,000 --> 00:04:19,000
You've got the gradients and the patterns and they're all you can just choose them all on here.

79
00:04:19,000 --> 00:04:24,000
Okay, so if we wanted solid, we could have just selected solid instead of a diagonal lines.

80
00:04:26,000 --> 00:04:28,000
If we want to gradients, we could have selected those here.

81
00:04:28,000 --> 00:04:33,000
To be honest, this is the way I usually choose my the pattern.

82
00:04:33,000 --> 00:04:35,000
I want to just select it in this pattern box.

83
00:04:35,000 --> 00:04:36,000
Okay.

84
00:04:36,000 --> 00:04:37,000
And that will be left there.

85
00:04:37,000 --> 00:04:43,000
So we'll go back to these diagonal lines and we've got this pattern here.

86
00:04:43,000 --> 00:04:46,000
And now the next line is a color.

87
00:04:46,000 --> 00:04:48,000
So what color do you want this hatch?

88
00:04:49,000 --> 00:04:52,000
And you've got all these kind of index colors here.

89
00:04:52,000 --> 00:04:55,000
We can click on more colors and you get even more.

90
00:04:55,000 --> 00:04:57,000
You can click on True Colors.

91
00:04:57,000 --> 00:05:02,000
If you know the actual code, you could type that in.

92
00:05:02,000 --> 00:05:05,000
Okay, You've got all different ways of selecting colors.

93
00:05:05,000 --> 00:05:10,000
Generally, I use this index color and there's usually enough here for us.

94
00:05:10,000 --> 00:05:13,000
Okay, It's usually enough for you to choose from.

95
00:05:13,000 --> 00:05:16,000
So let's make this red, okay?

96
00:05:18,000 --> 00:05:19,000
And this option here.

97
00:05:22,000 --> 00:05:23,000
Is the background color.

98
00:05:23,000 --> 00:05:27,000
So by default, the background color is just empty.

99
00:05:27,000 --> 00:05:30,000
It's kind of transparent, it's whatever is in the background.

100
00:05:31,000 --> 00:05:33,000
But we could change that.

101
00:05:33,000 --> 00:05:37,000
So it's a blue kind of solid with red lines.

102
00:05:37,000 --> 00:05:42,000
Again, we can't it's hard to see unless we zoom in because our our lines are too close together.

103
00:05:43,000 --> 00:05:44,000
I don't use that much, to be honest.

104
00:05:44,000 --> 00:05:47,000
I usually have no background.

105
00:05:47,000 --> 00:05:55,000
And the main thing to change for us here is this the distance between the lines and that can be done

106
00:05:55,000 --> 00:05:58,000
using this hatch pattern scale.

107
00:05:58,000 --> 00:06:00,000
Okay, so it's set to one.

108
00:06:01,000 --> 00:06:03,000
And that's too close together.

109
00:06:03,000 --> 00:06:05,000
Let's change that to ten.

110
00:06:06,000 --> 00:06:11,000
And now you can see we're getting nicer kind of pattern which will actually print as a pattern.

111
00:06:11,000 --> 00:06:12,000
It's not too close together.

112
00:06:12,000 --> 00:06:14,000
It won't just merge into one mess.

113
00:06:14,000 --> 00:06:20,000
So you can see these diagonal lines, but supposing we wanted them to run the other way, That's this

114
00:06:20,000 --> 00:06:21,000
option here angle.

115
00:06:21,000 --> 00:06:26,000
If we change that to 90, we can now have them running the other way.

116
00:06:26,000 --> 00:06:31,000
If we wanted to in vertical, we could change it to 45.

117
00:06:31,000 --> 00:06:34,000
Okay, 135 will be horizontal.

118
00:06:34,000 --> 00:06:38,000
So maybe you wanted to represent something like wooden, kind of boring.

119
00:06:38,000 --> 00:06:43,000
You could with a combination of scales and angles.

120
00:06:43,000 --> 00:06:45,000
You can make it look however you want.

121
00:06:45,000 --> 00:06:46,000
Really.

122
00:06:46,000 --> 00:06:50,000
So these are the main two properties are change the angle and the scale.

123
00:06:50,000 --> 00:06:53,000
And the angle is only really on these diagonal lines.

124
00:06:53,000 --> 00:06:57,000
You wouldn't change the angle really on brickwork usually or anything like that.

125
00:06:57,000 --> 00:07:05,000
But scale, certainly every hatch, if it's a pattern, it will require a certain scale and then we've

126
00:07:05,000 --> 00:07:06,000
got transparency.

127
00:07:06,000 --> 00:07:06,000
So.

128
00:07:08,000 --> 00:07:10,000
Let's say we had a solid hatch.

129
00:07:11,000 --> 00:07:13,000
And we had something underneath it.

130
00:07:13,000 --> 00:07:19,000
We wanted to fill in a room, maybe just to show, just to specify that any room highlighted in red

131
00:07:20,000 --> 00:07:22,000
needs a carpet, for instance.

132
00:07:22,000 --> 00:07:22,000
Okay.

133
00:07:22,000 --> 00:07:24,000
But we still want to see the things in the room.

134
00:07:24,000 --> 00:07:29,000
If it was furniture in the room, text in the room, this solid hatch would overpower it.

135
00:07:29,000 --> 00:07:33,000
You won't be able to see well, you can set a transparency, okay?

136
00:07:33,000 --> 00:07:37,000
And that allows you to actually see through the hatch.

137
00:07:38,000 --> 00:07:39,000
So you can use it.

138
00:07:39,000 --> 00:07:44,000
It's more of a kind of indicative reference kind of thing, but it does come in handy.

139
00:07:45,000 --> 00:07:46,000
I do use that.

140
00:07:46,000 --> 00:07:52,000
It can also with solid hashes, there can be a bit overpowering when you print them by putting transparency.

141
00:07:52,000 --> 00:07:56,000
It just kind of blurs them out a bit and makes them less overpowering.

142
00:07:56,000 --> 00:08:00,000
So that's the main options in terms of properties.

143
00:08:00,000 --> 00:08:01,000
Okay.

144
00:08:01,000 --> 00:08:01,000
So.

145
00:08:02,000 --> 00:08:05,000
We will ignore these for a moment.

146
00:08:05,000 --> 00:08:07,000
These are more advanced commands.
