1
00:00:08,000 --> 00:00:09,000
Okay.

2
00:00:09,000 --> 00:00:13,000
So we're getting through it now, getting through these basics, and we're just going to look in more

3
00:00:13,000 --> 00:00:15,000
detail at lines now.

4
00:00:15,000 --> 00:00:17,000
So I'm going to draw a window.

5
00:00:17,000 --> 00:00:17,000
Window Select.

6
00:00:17,000 --> 00:00:20,000
Remember left, click left, click again, press delete.

7
00:00:21,000 --> 00:00:24,000
And let's look at a basic line.

8
00:00:24,000 --> 00:00:30,000
So we left, click the line and you'll see it's asking us to specify the first point.

9
00:00:30,000 --> 00:00:34,000
Again, if you don't have this these boxes and this text, it's f 12 to turn it on and off.

10
00:00:35,000 --> 00:00:42,000
So you can see it's asking for a point and we're going to look at coordinates a bit later.

11
00:00:42,000 --> 00:00:47,000
For now, just left click anywhere in the screen and the options here.

12
00:00:48,000 --> 00:00:51,000
We're confronted with these boxes again and you'll see.

13
00:00:54,000 --> 00:00:57,000
It's asking you for two things.

14
00:00:57,000 --> 00:01:02,000
Okay, so the highlighted box in this case is the length.

15
00:01:03,000 --> 00:01:10,000
Let's say we wanted to draw a line which was 1000mm and it was drawn at 45 degrees.

16
00:01:10,000 --> 00:01:11,000
So it was kind of like that.

17
00:01:11,000 --> 00:01:18,000
Okay, so we type in a thousand and then again, not don't press enter.

18
00:01:18,000 --> 00:01:23,000
If we press the tab key, we've now switched to the other box and you can see this is locked.

19
00:01:23,000 --> 00:01:28,000
Now we've told it the line is 1000mm long, so it's not going to let us change that.

20
00:01:30,000 --> 00:01:32,000
What it does need to know is the angle.

21
00:01:32,000 --> 00:01:32,000
Okay.

22
00:01:32,000 --> 00:01:35,000
With that there being zero.

23
00:01:35,000 --> 00:01:45,000
So we can type in here 45 and then press return and it's created our line 1000mm long at 45 degrees

24
00:01:45,000 --> 00:01:46,000
and it's continuing the command.

25
00:01:46,000 --> 00:01:49,000
It will continue the line command until we say different.

26
00:01:49,000 --> 00:01:56,000
So if our next line wants to be 500, we type that in tab and maybe this is zero degrees.

27
00:01:56,000 --> 00:01:59,000
Okay, press enter and there we go.

28
00:01:59,000 --> 00:02:01,000
And we can carry on doing that.

29
00:02:03,000 --> 00:02:04,000
Until we've finished.

30
00:02:05,000 --> 00:02:07,000
Maybe we just want to draw a line by eye.

31
00:02:07,000 --> 00:02:07,000
You can just do that.

32
00:02:07,000 --> 00:02:10,000
You don't need to type anything in.

33
00:02:10,000 --> 00:02:10,000
Okay.

34
00:02:10,000 --> 00:02:12,000
Maybe we knew the length.

35
00:02:12,000 --> 00:02:15,000
The length of this line was going to be a thousand.

36
00:02:16,000 --> 00:02:17,000
You can press tab, but we don't know the angle.

37
00:02:17,000 --> 00:02:19,000
We can put any angle we want.

38
00:02:19,000 --> 00:02:22,000
We can just and it will tell you what the angle is, but you don't have to type it in.

39
00:02:23,000 --> 00:02:25,000
So maybe we just want to do it by eye there.

40
00:02:25,000 --> 00:02:25,000
Okay.

41
00:02:26,000 --> 00:02:30,000
And you can carry on going like that until you're finished.

42
00:02:30,000 --> 00:02:34,000
Or you can go back to the start and do right click.

43
00:02:34,000 --> 00:02:42,000
Now, one thing you may notice here, if I go back to the start, when I get near the end of this line

44
00:02:42,000 --> 00:02:49,000
here, I get this little kind of green box and it'll come up with a piece of text and end point.

45
00:02:49,000 --> 00:02:50,000
Okay.

46
00:02:51,000 --> 00:02:52,000
And that's called a no snap.

47
00:02:52,000 --> 00:02:55,000
We're going to look at that in a in a chapter coming up.

48
00:02:55,000 --> 00:02:56,000
So don't worry about that for now.

49
00:02:56,000 --> 00:02:59,000
I'm just going to end it there by right clicking.

50
00:03:00,000 --> 00:03:02,000
And there we have a line.

51
00:03:02,000 --> 00:03:08,000
But as I said before, if we select any points on this line now, they're going to be individual.

52
00:03:09,000 --> 00:03:15,000
So I'm going to left click and draw a window all around that and delete it.

53
00:03:15,000 --> 00:03:16,000
And we're going to do the same with polyline.

54
00:03:16,000 --> 00:03:20,000
So left click, polyline again, exactly the same.

55
00:03:20,000 --> 00:03:24,000
We're just going to start anywhere and it's exactly the same.

56
00:03:24,000 --> 00:03:29,000
You can see it's asking us for a length and an angle and we could type in those if we want this one.

57
00:03:29,000 --> 00:03:31,000
Maybe a thousand tab.

58
00:03:32,000 --> 00:03:35,000
45, enter.

59
00:03:35,000 --> 00:03:35,000
Okay.

60
00:03:35,000 --> 00:03:36,000
And you'll see.

61
00:03:38,000 --> 00:03:40,000
Before when I typed in 45.

62
00:03:40,000 --> 00:03:42,000
In fact, let me show you this again.

63
00:03:42,000 --> 00:03:47,000
If I type in a thousand for the length and then I do tab.

64
00:03:47,000 --> 00:03:48,000
Okay.

65
00:03:50,000 --> 00:03:52,000
As well as actually typing in the angle.

66
00:03:52,000 --> 00:03:55,000
You can you can you can tell AutoCAD which side you want to go.

67
00:03:55,000 --> 00:04:02,000
So obviously, with 45 degrees, we could be 45 degrees up here or we could be 45 degrees here.

68
00:04:03,000 --> 00:04:03,000
Okay.

69
00:04:03,000 --> 00:04:07,000
Now what I can do, I can move my mouse and I could kind of do it by eye like that.

70
00:04:07,000 --> 00:04:10,000
You can see it's telling me that's 45.

71
00:04:10,000 --> 00:04:11,000
I could left click there.

72
00:04:11,000 --> 00:04:12,000
Okay.

73
00:04:14,000 --> 00:04:17,000
If I go 1000 tab, I could do it down here.

74
00:04:17,000 --> 00:04:17,000
I can.

75
00:04:18,000 --> 00:04:19,000
I can do it anywhere.

76
00:04:19,000 --> 00:04:21,000
So I could do 45 down here.

77
00:04:22,000 --> 00:04:22,000
Okay.

78
00:04:23,000 --> 00:04:26,000
But you'll see 45 that way and 45 that way.

79
00:04:26,000 --> 00:04:28,000
It's basically seeing it as the same.

80
00:04:28,000 --> 00:04:39,000
So you can do that as a kind of a mixture of your of by doing it by eye and typing it in.

81
00:04:39,000 --> 00:04:42,000
Let's say I knew, I knew it was 47 degrees.

82
00:04:42,000 --> 00:04:45,000
I didn't want to kind of try and be exact like this.

83
00:04:45,000 --> 00:04:47,000
I'm going to type in 47.

84
00:04:47,000 --> 00:04:48,000
Okay.

85
00:04:50,000 --> 00:04:51,000
With my mouse up here.

86
00:04:51,000 --> 00:04:54,000
It's locked it to that.

87
00:04:54,000 --> 00:04:59,000
And you can see if I press tab, it's locked it now if I delete that.

88
00:05:05,000 --> 00:05:10,000
Okay if I do that again, type in 1000 and then tab.

89
00:05:11,000 --> 00:05:19,000
If I move my mouse down this way, as long as it's in the on the correct side and type in 45 tab, it's

90
00:05:19,000 --> 00:05:19,000
gone 45.

91
00:05:20,000 --> 00:05:21,000
So it depends which side your mouse is.

92
00:05:21,000 --> 00:05:24,000
You can just move your mouse.

93
00:05:24,000 --> 00:05:24,000
Okay.

94
00:05:25,000 --> 00:05:26,000
And that goes with length as well.

95
00:05:26,000 --> 00:05:27,000
If.

96
00:05:28,000 --> 00:05:35,000
So if I wanted my line, say 3000mm in this direction, I just move my mouse over here.

97
00:05:35,000 --> 00:05:36,000
Again, I'm not trying to.

98
00:05:36,000 --> 00:05:37,000
I'm not trying to get it to free.

99
00:05:38,000 --> 00:05:39,000
I'm just moving it in this direction.

100
00:05:39,000 --> 00:05:41,000
Letting go of the mouse, leaving it there.

101
00:05:41,000 --> 00:05:49,000
Type in 3000 tab and it knows that you want three files in that direction because it's moving it towards

102
00:05:49,000 --> 00:05:50,000
your mouse cursor.

103
00:05:51,000 --> 00:05:51,000
Okay.

104
00:05:51,000 --> 00:06:01,000
Now if I wanted it 40 kind of 45 degrees out there, I'd have to put in 135 because it is still taking

105
00:06:01,000 --> 00:06:03,000
it from the same zero point.

106
00:06:03,000 --> 00:06:03,000
Okay.

107
00:06:03,000 --> 00:06:07,000
So you have 45 degrees that way, 45 that way.

108
00:06:07,000 --> 00:06:13,000
But over here, it would be the kind of one, three, five either direction because there is zero.

109
00:06:13,000 --> 00:06:20,000
So you would put you would move your mouse up here generally in that direction, type in one, three,

110
00:06:20,000 --> 00:06:25,000
five and may go into and you can carry on doing that again.

111
00:06:25,000 --> 00:06:27,000
You can just do it by eye.

112
00:06:27,000 --> 00:06:29,000
If you wanted.

113
00:06:29,000 --> 00:06:31,000
And I'm going to right click to finish.

114
00:06:32,000 --> 00:06:36,000
And now when I click that, I actually did it in two different stages.

115
00:06:36,000 --> 00:06:38,000
So we've ended up with two polylines.

116
00:06:38,000 --> 00:06:43,000
Okay, now the thing with Polylines, we don't need to be straight lines at all.

117
00:06:43,000 --> 00:06:51,000
So if I left click Polyline again and I'm just going to click anywhere, you will see this bit of text

118
00:06:51,000 --> 00:06:52,000
next to my cursor.

119
00:06:52,000 --> 00:06:57,000
It actually says Specify next point or and then it's got a pull down arrow.

120
00:06:57,000 --> 00:07:00,000
And what that's saying is there are other options.

121
00:07:00,000 --> 00:07:03,000
You don't have to just specify the next point and the other options are down here.

122
00:07:03,000 --> 00:07:09,000
So we can do an arc half width length.

123
00:07:11,000 --> 00:07:12,000
On the width.

124
00:07:12,000 --> 00:07:15,000
Now the main thing you do here is the arc.

125
00:07:15,000 --> 00:07:19,000
Okay, so if you wanted a curved line, you could select Arc.

126
00:07:19,000 --> 00:07:23,000
And when you get these options down here, you might notice one letter.

127
00:07:23,000 --> 00:07:26,000
It's usually the first letter, but not always.

128
00:07:26,000 --> 00:07:29,000
But one of them is in blue and it's a higher case.

129
00:07:29,000 --> 00:07:33,000
That's giving you a clue to the shortcut, the keyboard shortcut.

130
00:07:33,000 --> 00:07:37,000
So if you want to do Arc, it's a return.

131
00:07:37,000 --> 00:07:40,000
If you wanted to do length, it's l return.

132
00:07:40,000 --> 00:07:40,000
Okay.

133
00:07:41,000 --> 00:07:42,000
So I'm going to do that again.

134
00:07:42,000 --> 00:07:43,000
I'm going to click Polyline.

135
00:07:43,000 --> 00:07:49,000
I'm going to left click anywhere, and this time I'm going to click with the left button arc.

136
00:07:49,000 --> 00:07:50,000
And now.

137
00:07:51,000 --> 00:08:00,000
We get the option to draw a curved line and it will carry on doing arcs until we tell it either to end

138
00:08:01,000 --> 00:08:03,000
the command or we can go back down here.

139
00:08:04,000 --> 00:08:07,000
And quit lying and go about two straight lines.

140
00:08:07,000 --> 00:08:08,000
Okay.

141
00:08:09,000 --> 00:08:13,000
And then and you can carry on swapping between the two as much as possible.

142
00:08:13,000 --> 00:08:15,000
Now with Axe, polyline, Axe.

143
00:08:15,000 --> 00:08:20,000
When you draw them, generally you draw the end point of the arc.

144
00:08:20,000 --> 00:08:24,000
You'll see it puts its own kind of curving based on the previous one.

145
00:08:26,000 --> 00:08:33,000
Just click to the endpoint and then right click to finish and what you can do, you can edit these later,

146
00:08:33,000 --> 00:08:34,000
but that's grips.

147
00:08:34,000 --> 00:08:38,000
We're going to look at grips in another chapter basically.

148
00:08:38,000 --> 00:08:38,000
For now.

149
00:08:38,000 --> 00:08:42,000
I wanted to show you again when we click on that, it selects the whole thing.

150
00:08:42,000 --> 00:08:43,000
We can delete that.

151
00:08:44,000 --> 00:08:47,000
So Polylines come with this a line.

152
00:08:47,000 --> 00:08:49,000
You cannot just say a line.

153
00:08:49,000 --> 00:08:50,000
There is no other options.

154
00:08:50,000 --> 00:08:51,000
With polyline.

155
00:08:51,000 --> 00:08:54,000
You get these options for arcs and things like that.

156
00:08:54,000 --> 00:08:54,000
Okay?

157
00:08:54,000 --> 00:09:01,000
And you can click left, click that, or you can just type in a return and that will do the same thing.

158
00:09:02,000 --> 00:09:06,000
It depends whether you prefer clicking or keyboard shortcuts.

159
00:09:10,000 --> 00:09:11,000
In this course.

160
00:09:11,000 --> 00:09:17,000
We're not going to use keyboard shortcuts much just because it's harder for me to show them to you.

161
00:09:17,000 --> 00:09:22,000
Sometimes you do a course and people are using shortcuts and you don't understand how they've done a

162
00:09:22,000 --> 00:09:24,000
command because you missed the shortcut.

163
00:09:24,000 --> 00:09:28,000
Or you you see as a command change because you can't see the mouse.

164
00:09:28,000 --> 00:09:30,000
That can sometimes confuse people.

165
00:09:30,000 --> 00:09:30,000
So.

166
00:09:30,000 --> 00:09:36,000
Okay, so we're not going to use that many keyboard shortcuts in this course just for that reason you

167
00:09:36,000 --> 00:09:37,000
wouldn't see what I'm doing.

168
00:09:38,000 --> 00:09:43,000
Okay, so with Polylines, you can do polyline, edits and more advanced things.

169
00:09:43,000 --> 00:09:44,000
We'll look at those later.

170
00:09:44,000 --> 00:09:49,000
But that's a basic overview of the lines, the line and the polyline.

171
00:09:50,000 --> 00:09:52,000
We also have this line here, which is arc.

172
00:09:52,000 --> 00:09:53,000
So.

173
00:09:54,000 --> 00:09:59,000
Whereas with a polyline we had the option to do lines and arcs within the same line if you were doing

174
00:09:59,000 --> 00:10:00,000
it separately.

175
00:10:01,000 --> 00:10:06,000
So let's just say you drew a random line like that and you wanted a curve without being a polyline for

176
00:10:06,000 --> 00:10:07,000
whatever reason.

177
00:10:08,000 --> 00:10:10,000
You can do an arc and an arc.

178
00:10:11,000 --> 00:10:13,000
As it hints to here, it's going to ask you for three points.

179
00:10:13,000 --> 00:10:14,000
So.

180
00:10:15,000 --> 00:10:21,000
Start a middle and an end, and that's the best way to get used to these.

181
00:10:21,000 --> 00:10:27,000
That, we've just learned, is to just click them, play about them, Just start creating some basic

182
00:10:27,000 --> 00:10:27,000
shapes.

183
00:10:27,000 --> 00:10:32,000
With or without dimensions and just get used to using them again.

184
00:10:32,000 --> 00:10:40,000
Because we set up our mouse with the left click and the right click to finish the command is right click.

185
00:10:40,000 --> 00:10:41,000
Okay.

186
00:10:41,000 --> 00:10:45,000
But what we can also do if we now wanted to draw that line again.

187
00:10:45,000 --> 00:10:50,000
So let me show you if we selected polyline, okay, And we left click left, click left, click right

188
00:10:50,000 --> 00:10:51,000
click to end.

189
00:10:51,000 --> 00:10:53,000
And now I want another polyline.

190
00:10:54,000 --> 00:10:59,000
We can right click and it will repeat the last command.

191
00:10:59,000 --> 00:11:05,000
So anytime whatever command we use, whether it's move copy, any of these rectangle, if you then want

192
00:11:05,000 --> 00:11:12,000
to do it again, all you need to do is right click mouse and it will repeat the last command.

193
00:11:12,000 --> 00:11:16,000
That's one of the reasons we set it up that way and it really does speed things up.

194
00:11:16,000 --> 00:11:18,000
But you'll see me doing that in this course.

195
00:11:20,000 --> 00:11:25,000
And so I'll do a command and then I'll do it again.

196
00:11:25,000 --> 00:11:27,000
And you might think, Well, mine's not repeating.

197
00:11:27,000 --> 00:11:29,000
It needs me to click up here.

198
00:11:29,000 --> 00:11:29,000
What I'm.

199
00:11:29,000 --> 00:11:32,000
All I'm doing is right clicking the mouse to repeat the last command.

200
00:11:32,000 --> 00:11:33,000
Okay.

201
00:11:33,000 --> 00:11:35,000
So if you see me doing that, that's why.

202
00:11:41,000 --> 00:11:41,000
Okay.

203
00:11:41,000 --> 00:11:43,000
In the next chapter, we're going to look at.

204
00:11:43,000 --> 00:11:45,000
Oh, snaps and object snaps.
