1
00:00:10,000 --> 00:00:10,000
Okay.

2
00:00:10,000 --> 00:00:11,000
Welcome back.

3
00:00:11,000 --> 00:00:16,000
So now we're going to look at just a bit more about how we use our mouse and how we view and things

4
00:00:16,000 --> 00:00:16,000
like that.

5
00:00:16,000 --> 00:00:20,000
So first thing we want to talk about is the mouse.

6
00:00:20,000 --> 00:00:24,000
And most people will have a mouse of some sort.

7
00:00:24,000 --> 00:00:31,000
Now, I recommend for this course you have a kind of basic three button mouse.

8
00:00:31,000 --> 00:00:36,000
And by free button I mean a left button, a right button and a middle wheel stroke button.

9
00:00:36,000 --> 00:00:36,000
Okay.

10
00:00:36,000 --> 00:00:42,000
So if you can get those, if you don't already have them, it will make following along with this course

11
00:00:42,000 --> 00:00:43,000
much, much easier.

12
00:00:43,000 --> 00:00:45,000
I think most people have that.

13
00:00:45,000 --> 00:00:49,000
What tends to happen is people have more advanced mouse with buttons everywhere.

14
00:00:50,000 --> 00:00:55,000
Later on, when you get used to the software, you can program commands to the extra buttons.

15
00:00:56,000 --> 00:01:02,000
But for so much variety in mice out there, it'd be impossible for me to go through various settings

16
00:01:02,000 --> 00:01:03,000
and it'd be very confusing.

17
00:01:03,000 --> 00:01:07,000
So we're just going to go back to basics for this and we're going to use a left button, a right button

18
00:01:07,000 --> 00:01:11,000
and a middle button with the middle button also being a wheel.

19
00:01:11,000 --> 00:01:12,000
Okay?

20
00:01:12,000 --> 00:01:16,000
And I'll show you how how you can use that.

21
00:01:16,000 --> 00:01:21,000
Now, in the previous chapter, we set up the right click, if you remember, and that's all about this

22
00:01:21,000 --> 00:01:23,000
kind of right clicking, which we're going to do.

23
00:01:23,000 --> 00:01:27,000
And throughout the course you're going to see me do that early on in the course.

24
00:01:27,000 --> 00:01:29,000
I'm going to point out what I'm doing.

25
00:01:29,000 --> 00:01:34,000
Then as we progress, you should know what I'm doing, whether I'm right clicking, left clicking,

26
00:01:34,000 --> 00:01:36,000
and it's a very intuitive way of working.

27
00:01:36,000 --> 00:01:38,000
So you'll you'll be able to follow along.

28
00:01:38,000 --> 00:01:38,000
Okay.

29
00:01:40,000 --> 00:01:41,000
Right.

30
00:01:46,000 --> 00:01:53,000
So in order for me to demonstrate the viewing and the zooming and things, I need something on my screen.

31
00:01:53,000 --> 00:01:56,000
So I'm going to draw a basic rectangle.

32
00:01:56,000 --> 00:01:56,000
Okay.

33
00:01:59,000 --> 00:02:02,000
We're going to in the next couple of chapters, we're going to go over in more detail creating objects.

34
00:02:02,000 --> 00:02:07,000
So you don't necessarily need to follow on with creating these objects yet.

35
00:02:07,000 --> 00:02:11,000
But I do need something on my screen just to demonstrate the zooming and things.

36
00:02:11,000 --> 00:02:16,000
So up here we have our draw commands and we have one which is Rectangle which is here.

37
00:02:16,000 --> 00:02:22,000
So I'm going to left click that and I'm just going to select anywhere on my screen.

38
00:02:22,000 --> 00:02:28,000
I'm going to left click and it's going to ask me for another corner and I'm going to left click again.

39
00:02:28,000 --> 00:02:29,000
Simple as that.

40
00:02:29,000 --> 00:02:32,000
Okay, now I've got a rectangle on my screen.

41
00:02:33,000 --> 00:02:34,000
So.

42
00:02:35,000 --> 00:02:38,000
The way I'm doing this, I'm kind of moving that about.

43
00:02:38,000 --> 00:02:39,000
This is called panning.

44
00:02:39,000 --> 00:02:40,000
Okay.

45
00:02:40,000 --> 00:02:43,000
And you may know this from other software, so I'm sorry.

46
00:02:43,000 --> 00:02:46,000
I'm going I am going back to the beginning, just so we're all on the same page.

47
00:02:47,000 --> 00:02:50,000
And I'm doing this by holding down that middle wheel on my mouse.

48
00:02:50,000 --> 00:02:56,000
So if you press that middle wheel and hold it down, you'll see the cursor turns into a hand and with

49
00:02:56,000 --> 00:03:01,000
it held down, when you move your mouse, you will kind of pan that along.

50
00:03:02,000 --> 00:03:04,000
Okay, now you're not moving that rectangle.

51
00:03:04,000 --> 00:03:06,000
What you're doing is you're moving the view.

52
00:03:06,000 --> 00:03:11,000
So if you imagine the camera's pointing at the rectangle, you're panning the camera around.

53
00:03:11,000 --> 00:03:17,000
So if there was other objects here and again, don't worry so much about what I'm doing, it's just

54
00:03:17,000 --> 00:03:19,000
a demonstration.

55
00:03:19,000 --> 00:03:24,000
So if I was to pan, I'm not moving the individual rectangle.

56
00:03:24,000 --> 00:03:26,000
If I was moving it.

57
00:03:27,000 --> 00:03:29,000
It would be doing that and the other.

58
00:03:29,000 --> 00:03:35,000
So so what I'm doing is I'm panning the view again, Don't worry about these, what I'm doing with the

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

60
00:03:35,000 --> 00:03:36,000
We're going to get into that in a minute.

61
00:03:36,000 --> 00:03:37,000
I'm just demonstrating the view.

62
00:03:37,000 --> 00:03:43,000
So I'm panning that view now with a middle wheel, you can also roll the wheel and that will allow you

63
00:03:43,000 --> 00:03:44,000
to zoom in and out.

64
00:03:46,000 --> 00:03:46,000
Okay.

65
00:03:46,000 --> 00:03:54,000
So it's that mixture of panning and zooming in and out that we use all the time to move around our drawing.

66
00:03:54,000 --> 00:03:55,000
And they used to be.

67
00:03:55,000 --> 00:03:58,000
Well, there still is of a view command viewing windows and viewing.

68
00:03:59,000 --> 00:04:03,000
We do use those not as much as we used to these days with the mice.

69
00:04:03,000 --> 00:04:05,000
It's mainly done with the wheel.

70
00:04:05,000 --> 00:04:10,000
And if you see someone doing CAD experience user, you'll see them panning and zooming all day long.

71
00:04:10,000 --> 00:04:11,000
Okay.

72
00:04:12,000 --> 00:04:17,000
The only other main one is if let's say you got something down here and you've been working away down

73
00:04:17,000 --> 00:04:18,000
here.

74
00:04:18,000 --> 00:04:19,000
Okay.

75
00:04:20,000 --> 00:04:21,000
And you pan along.

76
00:04:21,000 --> 00:04:23,000
Oh, and now you're a bit lost where you are.

77
00:04:23,000 --> 00:04:24,000
You're panning around.

78
00:04:24,000 --> 00:04:25,000
Where's my drawing?

79
00:04:25,000 --> 00:04:26,000
Okay.

80
00:04:27,000 --> 00:04:30,000
What you can do if you double click that middle wheel quite fast.

81
00:04:31,000 --> 00:04:38,000
It zooms out to extents and zoom extents just means I'm going to zoom out to the extent of your model,

82
00:04:38,000 --> 00:04:38,000
your drawing.

83
00:04:38,000 --> 00:04:44,000
So everything in this file on this screen, it will zoom out to encompass all of that.

84
00:04:44,000 --> 00:04:45,000
Okay.

85
00:04:45,000 --> 00:04:46,000
And that's great.

86
00:04:46,000 --> 00:04:51,000
If ever you do get kind of lost, you know, sometimes you can end up down here and you're looking for

87
00:04:51,000 --> 00:04:54,000
your you can just double click and that will zoom there.

88
00:04:54,000 --> 00:05:02,000
So that's so you've got zoom, pan and extents and that's all controlled by that same middle wheel.

89
00:05:02,000 --> 00:05:03,000
Okay.

90
00:05:05,000 --> 00:05:11,000
One thing you may notice on my screen and you may or may not have it on yours, is you can see these

91
00:05:11,000 --> 00:05:14,000
faint kind of grid lines here.

92
00:05:14,000 --> 00:05:18,000
This is it's known as grid for obvious reasons.

93
00:05:18,000 --> 00:05:23,000
It's AutoCAD way of helping you work out what the measurements of units are.

94
00:05:23,000 --> 00:05:28,000
If you see the more you zoom in, the more your grid kind of separates down into smaller grids.

95
00:05:29,000 --> 00:05:31,000
Some people like it, some people don't.

96
00:05:31,000 --> 00:05:37,000
To be honest, it's one of those things that used to be used a lot more than it's used now.

97
00:05:38,000 --> 00:05:39,000
It is quite faint.

98
00:05:39,000 --> 00:05:43,000
Sometimes I work away without even registering it.

99
00:05:43,000 --> 00:05:44,000
Okay.

100
00:05:44,000 --> 00:05:49,000
If it gets in your way or you don't like it, you can turn it on and off with this here.

101
00:05:49,000 --> 00:05:55,000
So that's probably how most people work now with the grid off again, because it's so faint sometimes

102
00:05:55,000 --> 00:05:57,000
I just don't forget it's even there.

103
00:05:57,000 --> 00:05:58,000
And don't turn it off.

104
00:05:58,000 --> 00:06:00,000
So you'll see me working with it on.

105
00:06:00,000 --> 00:06:03,000
It's just because I don't actually I don't mind it.

106
00:06:03,000 --> 00:06:04,000
I just kind of block it out.

107
00:06:04,000 --> 00:06:08,000
But it has no use really for me.

108
00:06:08,000 --> 00:06:12,000
So you can turn it off when you start working in paper.

109
00:06:14,000 --> 00:06:18,000
Then it can get in the way because you're working with a white background.

110
00:06:18,000 --> 00:06:21,000
When I do turn it off because it's much more noticeable.

111
00:06:21,000 --> 00:06:26,000
But if you don't know what I mean by working in paper space, just don't worry about that.

112
00:06:26,000 --> 00:06:27,000
That's something you'll do later in your course.

113
00:06:27,000 --> 00:06:30,000
The main thing I would say is.

114
00:06:31,000 --> 00:06:34,000
If I turn it off, I'll just get used to it being there and ignoring it.

115
00:06:34,000 --> 00:06:35,000
And that's the grid.

116
00:06:38,000 --> 00:06:42,000
And that's basically it with views at the moment.

117
00:06:42,000 --> 00:06:43,000
There is a view cube up here.

118
00:06:43,000 --> 00:06:44,000
We're going to look at that.

119
00:06:44,000 --> 00:06:45,000
That's a bit complicated for now.

120
00:06:46,000 --> 00:06:53,000
This will get you through 90% of what you need in terms of views, just zooming, panning and zooming

121
00:06:53,000 --> 00:06:54,000
extents.

122
00:06:54,000 --> 00:06:54,000
Okay.

123
00:06:54,000 --> 00:06:58,000
So in the next chapter, we'll look more on selecting objects.
