1
00:00:09,000 --> 00:00:09,000
Right.

2
00:00:09,000 --> 00:00:12,000
So now we can start adding these internal walls.

3
00:00:12,000 --> 00:00:18,000
And when you're creating things in AutoCAD, it's always good to be thinking to yourself, what's the

4
00:00:18,000 --> 00:00:21,000
easiest way to to do this?

5
00:00:21,000 --> 00:00:28,000
When you get more experienced as you're actually modeling or drawing a line, your brain will be kind

6
00:00:28,000 --> 00:00:34,000
of one step ahead and it will already be thinking how you're going to create the next object.

7
00:00:34,000 --> 00:00:37,000
You won't even be thinking about the object you're actually drawing at that point.

8
00:00:37,000 --> 00:00:40,000
But that's further down the line when you get more advanced.

9
00:00:40,000 --> 00:00:46,000
For now, let's just have a look at this and think what would be the easiest way to create it?

10
00:00:46,000 --> 00:00:48,000
So we can see these lines.

11
00:00:48,000 --> 00:00:52,000
We have a main corridor here, which is basically two lines.

12
00:00:52,000 --> 00:00:59,000
If we ignore the doors for a minute and then we look at these rooms, these lines dividing the room,

13
00:00:59,000 --> 00:01:02,000
the rooms are actually the same length either side of a corridor.

14
00:01:03,000 --> 00:01:07,000
So I'm already thinking I don't want to draw things twice.

15
00:01:07,000 --> 00:01:14,000
I could just put these walls in right the way across and then I can add the two walls for the corridor.

16
00:01:14,000 --> 00:01:19,000
And with some trimming and filleting and things, I can just kind of cut all those out.

17
00:01:19,000 --> 00:01:19,000
So that's.

18
00:01:20,000 --> 00:01:24,000
That's the way I'd like to go and that's the way we'll look at doing it in this course.

19
00:01:24,000 --> 00:01:31,000
So first thing I'm going to do is set out these walls that are running north to south on this plan,

20
00:01:31,000 --> 00:01:38,000
and the first one is going to be 4100mm or 4.1m across in our millimeters.

21
00:01:40,000 --> 00:01:45,000
Example, fate is 13ft six millimetres, 4100.

22
00:01:45,000 --> 00:01:46,000
So I'm going to set that out first.

23
00:01:46,000 --> 00:01:51,000
And also the thickness of these walls There they are, 100mm.

24
00:01:51,000 --> 00:01:51,000
Okay.

25
00:01:51,000 --> 00:01:57,000
So all these internal walls are 100mm or 4in for the Imperial guys.

26
00:01:57,000 --> 00:01:58,000
So.

27
00:02:01,000 --> 00:02:02,000
Let's look at that.

28
00:02:02,000 --> 00:02:07,000
We want a line, first line, first internal war line is going to run down here.

29
00:02:07,000 --> 00:02:14,000
It's going to be 4.1m or 4100mm off of this line and it's going to run all the way down and then be

30
00:02:14,000 --> 00:02:15,000
100mm thick.

31
00:02:15,000 --> 00:02:17,000
So how can we do that?

32
00:02:17,000 --> 00:02:21,000
We could offset a line here, but this is a this is a polyline, okay?

33
00:02:21,000 --> 00:02:27,000
So it would end up offsetting the whole rectangle if I clicked on offset and try to offset that, it

34
00:02:27,000 --> 00:02:29,000
would offset the whole rectangle there.

35
00:02:29,000 --> 00:02:39,000
Now I could draw a line there and then I could offset that and it would just offset that line.

36
00:02:39,000 --> 00:02:43,000
But then we're adding geometry and it can get messy later on if we forget to delete it.

37
00:02:43,000 --> 00:02:47,000
There's an easy way to start your line.

38
00:02:47,000 --> 00:02:53,000
To start this line at a point that is 4.1m from there.

39
00:02:53,000 --> 00:02:58,000
So what we do, we turn on this down here, this step in reference line.

40
00:02:58,000 --> 00:03:06,000
Okay, we turn that on and that will let us kind of select a start point without creating any extra

41
00:03:06,000 --> 00:03:07,000
geometry.

42
00:03:07,000 --> 00:03:08,000
And I'll show you what I mean.

43
00:03:08,000 --> 00:03:14,000
Now I'm going to go to polyline and I'm going to hover over this corner, make sure you've got your

44
00:03:14,000 --> 00:03:17,000
oh snaps on as we did in the Snaps chapter.

45
00:03:17,000 --> 00:03:26,000
And you've got at least I would say for this one, let's put on end point midpoint perpendicular and.

46
00:03:31,000 --> 00:03:32,000
Intersection.

47
00:03:33,000 --> 00:03:36,000
So hover over this corner.

48
00:03:36,000 --> 00:03:37,000
Don't click anything and you'll see.

49
00:03:37,000 --> 00:03:40,000
When we first hover over it, we get our normal.

50
00:03:41,000 --> 00:03:42,000
Dimension Square.

51
00:03:42,000 --> 00:03:46,000
But then it kind of changes and it will say end point.

52
00:03:46,000 --> 00:03:53,000
Okay, so hover your cursor over it until it changes and it says end point when you get this.

53
00:03:54,000 --> 00:03:59,000
Move your mouse along the wall that you want to measure along.

54
00:03:59,000 --> 00:03:59,000
Okay.

55
00:04:01,000 --> 00:04:07,000
So you go endpoint and make sure when you do it, you get this kind of green dashed.

56
00:04:07,000 --> 00:04:11,000
If you can see there's a green dashed horizontal line following my wall where I am.

57
00:04:12,000 --> 00:04:20,000
What's happening here is it's allowing me to put in a start point a lot like when we put type in a length,

58
00:04:20,000 --> 00:04:25,000
when we create in geometry, we can also now doing this, we can just put in a distance for our start

59
00:04:25,000 --> 00:04:25,000
point.

60
00:04:25,000 --> 00:04:35,000
So I'm going to type in 4100 and I'm going to press enter and you'll see now it's moved the start point

61
00:04:35,000 --> 00:04:37,000
of that line.

62
00:04:37,000 --> 00:04:37,000
Okay.

63
00:04:37,000 --> 00:04:41,000
And if I turn off the one with F8, it's moved it.

64
00:04:42,000 --> 00:04:46,000
To this point here, which is four files on 100mm long.

65
00:04:46,000 --> 00:04:52,000
And I'm just going to go down and because we've got perpendicular on, it will allow us to snap perpendicular

66
00:04:52,000 --> 00:04:55,000
and I can left click and right click to finish.

67
00:04:55,000 --> 00:04:56,000
Okay.

68
00:04:56,000 --> 00:05:04,000
And if I do a distance measurement from here to here, you can see it's 4100.

69
00:05:04,000 --> 00:05:09,000
So I'm just going to show you that again because it can be a bit difficult to follow.

70
00:05:09,000 --> 00:05:15,000
Make sure you've got your oh, snap on with at least end point and perpendicular and make sure you've

71
00:05:15,000 --> 00:05:17,000
got this highlighted here.

72
00:05:17,000 --> 00:05:19,000
Click on your polyline.

73
00:05:19,000 --> 00:05:25,000
Don't click, but hover over the corner until it changes to just say End Point, move it along the line.

74
00:05:25,000 --> 00:05:27,000
You wish to measure along.

75
00:05:27,000 --> 00:05:29,000
Make sure you've got the green dashed line.

76
00:05:29,000 --> 00:05:31,000
You don't have to move it in any.

77
00:05:31,000 --> 00:05:34,000
Just move it to the correct kind of direction you want to go.

78
00:05:34,000 --> 00:05:39,000
You don't have to try and get the dimension correct for 4100 just in the general direction.

79
00:05:39,000 --> 00:05:42,000
You want to measure along, you could move it right out here if you want.

80
00:05:42,000 --> 00:05:45,000
As long as you've got this green dashed line, then put in the dimension.

81
00:05:45,000 --> 00:05:46,000
You want to move along.

82
00:05:47,000 --> 00:05:49,000
4100 press enter.

83
00:05:49,000 --> 00:05:53,000
And now it's moved the start point to that position.

84
00:05:53,000 --> 00:05:59,000
Then using the perpendicular stamp, you can left click right click to finish that command.

85
00:05:59,000 --> 00:06:00,000
And there you go.

86
00:06:01,000 --> 00:06:03,000
And now we can use the offset command.

87
00:06:03,000 --> 00:06:09,000
And I'm going to type in 100, which is the thickness of our internal wall, and I'm going to offset

88
00:06:09,000 --> 00:06:11,000
and make sure you offset to the right side.

89
00:06:13,000 --> 00:06:14,000
There we go.

90
00:06:15,000 --> 00:06:22,000
So that is our first wall and that is the wall here running all the way down.

91
00:06:22,000 --> 00:06:26,000
The next one is going to be exactly the same process, but six meters.

92
00:06:26,000 --> 00:06:28,000
So let's do that again.

93
00:06:28,000 --> 00:06:29,000
Polyline.

94
00:06:29,000 --> 00:06:31,000
Hover over this corner.

95
00:06:32,000 --> 00:06:33,000
Wait for it to change.

96
00:06:33,000 --> 00:06:35,000
Move along.

97
00:06:35,000 --> 00:06:37,000
Make sure you get your green dashed line.

98
00:06:37,000 --> 00:06:44,000
Type in 6000, enter and then snap perpendicular.

99
00:06:44,000 --> 00:06:45,000
Now, right.

100
00:06:45,000 --> 00:06:46,000
Offset.

101
00:06:46,000 --> 00:06:47,000
It's already set to 100.

102
00:06:47,000 --> 00:06:52,000
So we can just right click because because it remembers the last offset you did.

103
00:06:52,000 --> 00:06:53,000
And we've got another wall.

104
00:06:55,000 --> 00:06:59,000
And again, our next one is another six.

105
00:06:59,000 --> 00:07:08,000
Now we've, we've offset this one six metres and now we want to offset this one six metres so we can

106
00:07:08,000 --> 00:07:16,000
do it the same way or we can just go copy and I'm going to window select both those lines right click

107
00:07:16,000 --> 00:07:21,000
and for the base point I'm going to click here and drop it to that point there.

108
00:07:21,000 --> 00:07:27,000
And because I basically copied this wall using that base point, I know that this is 6000 as well as

109
00:07:27,000 --> 00:07:28,000
that 6000.

110
00:07:28,000 --> 00:07:28,000
Okay?

111
00:07:28,000 --> 00:07:29,000
It's the same dimension.

112
00:07:29,000 --> 00:07:32,000
If you're doing the same dimension, you can just do it that way.

113
00:07:32,000 --> 00:07:35,000
Or you could have done it the same way we did the others.

114
00:07:35,000 --> 00:07:36,000
It's completely up to you.

115
00:07:38,000 --> 00:07:42,000
So now we've got these three walls running this way.

116
00:07:42,000 --> 00:07:43,000
We're going to put.

117
00:07:44,000 --> 00:07:49,000
Two walls running horizontal and this is going to be 3600 down.

118
00:07:50,000 --> 00:07:51,000
So same process.

119
00:07:51,000 --> 00:07:53,000
Polyline hover over there.

120
00:07:53,000 --> 00:07:55,000
Wait for it to change.

121
00:07:55,000 --> 00:07:56,000
Move it down.

122
00:07:56,000 --> 00:08:00,000
We've got our green line type in 3600.

123
00:08:00,000 --> 00:08:01,000
Enter.

124
00:08:01,000 --> 00:08:03,000
And I'm going to go right the way across.

125
00:08:04,000 --> 00:08:05,000
Get perpendicular, snap.

126
00:08:05,000 --> 00:08:06,000
Right click.

127
00:08:06,000 --> 00:08:07,000
Done.

128
00:08:07,000 --> 00:08:07,000
Sorry.

129
00:08:07,000 --> 00:08:10,000
Left click to place it, then right click done.

130
00:08:10,000 --> 00:08:11,000
Offset that.

131
00:08:12,000 --> 00:08:16,000
100 saved right click offset.

132
00:08:17,000 --> 00:08:17,000
There we go.

133
00:08:18,000 --> 00:08:23,000
And now I'm going to just offset this 2000 here.

134
00:08:23,000 --> 00:08:34,000
So I'll go offset type in 2000, offset that one right click to finish command, right click to repeat

135
00:08:34,000 --> 00:08:35,000
command.

136
00:08:35,000 --> 00:08:40,000
This time it's 100 enter and I'll offset that.

137
00:08:41,000 --> 00:08:49,000
And just as a check, I'm going to make sure that this distance here is 3600, which it is.

138
00:08:50,000 --> 00:08:52,000
So we've got our internal walls now.

139
00:08:55,000 --> 00:08:56,000
We just need to tidy it up.

140
00:08:57,000 --> 00:08:57,000
Okay.

141
00:08:57,000 --> 00:09:01,000
If you look on our drawing where our walls cross, we've got these crossing lines.

142
00:09:01,000 --> 00:09:03,000
We don't want any walls across the corridor.

143
00:09:03,000 --> 00:09:05,000
We don't want a wall here.

144
00:09:05,000 --> 00:09:10,000
Most of that can be done or all of it can be done with just trim, extend and maybe some fillets.

145
00:09:10,000 --> 00:09:12,000
So let's look at trimming first.

146
00:09:16,000 --> 00:09:24,000
I'm going to select Trim Left Click Trim, and I'm going to click on these kind of in the corridor walls.

147
00:09:24,000 --> 00:09:31,000
But on the room side, I'm going to right click to complete the selection, and now it's going to ask

148
00:09:31,000 --> 00:09:32,000
us what we want to trim.

149
00:09:32,000 --> 00:09:38,000
So I'm going to just left click in the space here and draw a window right the way down the corridor,

150
00:09:38,000 --> 00:09:41,000
left click right click to finish Command.

151
00:09:42,000 --> 00:09:43,000
And that's taken all those out.

152
00:09:45,000 --> 00:09:50,000
I don't want these little pieces here because these walls are kind of I just want the internal walls

153
00:09:50,000 --> 00:09:53,000
to be one complete kind of flowing section.

154
00:09:53,000 --> 00:09:54,000
So we're hatch.

155
00:09:54,000 --> 00:09:55,000
It will fill them all in.

156
00:09:56,000 --> 00:09:58,000
We can do the same command.

157
00:09:58,000 --> 00:10:00,000
I'm going to select Trim.

158
00:10:00,000 --> 00:10:02,000
I'm going to left click in this space.

159
00:10:02,000 --> 00:10:05,000
I'm going to select all these lines with a window going this way.

160
00:10:05,000 --> 00:10:07,000
Remember, if we went the other way, we'd have to complete.

161
00:10:08,000 --> 00:10:10,000
We'd have to cover the whole line this way, we just touch them.

162
00:10:10,000 --> 00:10:12,000
So I want to trim.

163
00:10:12,000 --> 00:10:20,000
I'm going to right click and now I'm going to just left click and select these objects here to trim

164
00:10:20,000 --> 00:10:21,000
them out.

165
00:10:22,000 --> 00:10:23,000
And there we go.

166
00:10:23,000 --> 00:10:25,000
Same again down here.

167
00:10:32,000 --> 00:10:33,000
Okay.

168
00:10:36,000 --> 00:10:38,000
Now, this one is a bit different.

169
00:10:38,000 --> 00:10:42,000
Here we wanted this corner.

170
00:10:42,000 --> 00:10:44,000
We don't want the wall and we want this corner.

171
00:10:44,000 --> 00:10:46,000
This is our open reception area.

172
00:10:46,000 --> 00:10:53,000
So what I'll do here, I'll click on fill it, I'm going to click R for radius type R enter and it's

173
00:10:53,000 --> 00:10:55,000
already set to zero, but I like to just do that.

174
00:10:55,000 --> 00:10:58,000
Make sure we haven't got a curved radius on there.

175
00:10:58,000 --> 00:11:03,000
Sometimes you could have a very, very small curved radius and you don't know about it.

176
00:11:03,000 --> 00:11:09,000
So I've set that to zero and now I can select these two lines and give it a radius and all I need to

177
00:11:09,000 --> 00:11:13,000
do is delete that one and we're done.

178
00:11:13,000 --> 00:11:16,000
And that is our internal walls.

179
00:11:17,000 --> 00:11:17,000
Easy.

180
00:11:17,000 --> 00:11:18,000
So.

181
00:11:21,000 --> 00:11:22,000
Already.

182
00:11:22,000 --> 00:11:26,000
We've got our main building layout and our room separations done.

183
00:11:26,000 --> 00:11:29,000
Just using those few commands.

184
00:11:29,000 --> 00:11:36,000
So you probably seen now already what I've spoken about in the basic modules section, although AutoCAD

185
00:11:36,000 --> 00:11:40,000
is really powerful and it's got lots of commands for different things.

186
00:11:40,000 --> 00:11:46,000
The main kind of tool belt that you use is just a very small selection of commands that allow you to

187
00:11:46,000 --> 00:11:47,000
do quite a lot of things.

188
00:11:49,000 --> 00:11:55,000
So in the next chapter, we're going to look at putting the doors in so you can actually get into these

189
00:11:55,000 --> 00:11:55,000
rooms.
