- [Instructor] So, it looks like

2

we're getting a pretty good handle

3

on creating this schematic design for our project.

4

Let's talk about composites.

5

As we progress through this process

6

of girly design development.

7

And we're laying it out,

8

trying to figure out what the materials are.

9

And where the project is oriented.

10

It's good for us to understand what composites are.

11

So, I'm going to open up this section.

12

So, I'm going to right click on this.

13

And I'm going to open with current view settings.

14

And click on that.

15

And so, let's hide our site.

16

And let's just get a better look at these walls

17

and some of these floors.

18

So, these walls and floors

19

are made up of a composite material.

20

And where we can find that is up here options.

21

And if I go to composites, I can click on this here.

22

But let's say I want to make a change,

23

specifically, to this composite here.

24

And I don't necessarily want to change the type of wall it is,

25

I just want to change the composite

26

that makes this wall up.

27

So, if I use my Alt and click.

28

Now, I have absorbed the properties of that wall.

29

And so, if I go to options and then I go to composites,

30

it should bring up that same wall.

31

So, it looks like we have the W07 wall.

32

It's pretty generic.

33

That's kind of what it was designed for.

34

But I want to make it a little bit more complex.

35

Maybe I've figured out some more about what the client wants

36

or what I want to implement in the design.

37

Maybe it's actually going to be five

38

and a half inch exterior walls.

39

So, I can change that there.

40

And maybe I know what the exterior skin is going to be.

41

So let's insert a skin.

42

Let's insert a couple real quick.

43

So what it's doing is duplicating our skins

44

from the previous one that we had.

45

And what I want to do

46

is I want to create a waterproofing membrane.

47

So, I can click in here and I can go and click here.

48

And these are the building materials.

49

So, we talked about this earlier in the course,

50

the building materials.

51

And this is where understanding what the building materials

52

are and how they're used is going to be critical.

53

So, I'm just going to put a waterproofing layer.

54

And I like to make my composite

55

as close to the real world situation as they would.

56

So, let's just make this roughly about an 16th

57

of an inch thick.

58

And let's make this an air barrier.

59

And let's see here.

60

So, if I type in air barrier,

61

let's just use air space.

62

And let's make that about an inch.

63

And let's put some siding on it.

64

So, let's try to find some siding.

65

So, we have siding right there.

66

So, I'm going to select that.

67

And let's make it like a three quarter of an inch siding.

68

And so, there's kind of our composite.

69

And this is two different views you're looking at.

70

So you're looking at what it will look like

71

when you cut through.

72

Like we're looking at in here.

73

And what the surface materials will look like.

74

So this is if you were cutting through it in 3D.

75

So let's look at both of those really quickly.

76

And so, just pushing OK.

77

And there you go.

78

So, it has changed all of the instances

79

of that wall composite throughout the project.

80

So, this is a powerful way to make adjustments.

81

It can be kind of risky because if you have made adjustments

82

to a wall that occurs in different locations,

83

you just have to be cognizant

84

of where those occurrences are.

85

So, let's go back to the floor plan.

86

And I just want to show you what it looks like in 3D.

87

So we're going to use a tool called the marquee tool.

88

For me, the shortcut command is two.

89

And so we're going to use the dark marquee.

90

And the marquee allows us to marquee an area.

91

And so I'm just go up to that section line

92

that we're just looking at.

93

And I can click.

94

And this will allow me to marquee areas

95

throughout all the elevations of the building.

96

And so if I right click, I can say

97

show selection or marquee area in 3D.

98

And then let me hide that again.

99

And let me just show you how you could do this differently.

100

I'm coming back to a view where I'm seeing that mesh again.

101

And I don't really want to see it right now.

102

I can right click.

103

Pick up the settings for my section.

104

And then I inject the settings here.

105

So, it's taking the settings that I've was using

106

to look at the section and it just injected those.

107

So the layer combinations that I was looking at.

108

So let's look at this composite.

109

So that's the composite.

110

So we can see that there's this little airspace

111

between the siding and then we have our chip.

112

And so, maybe we want to make another change to this.

113

So again, if I click on it,

114

I push the eyedropper.

115

And I go to options.

116

I go to composites.

117

And so picks up that same one.

118

I can duplicate this and I can recreate it.

119

But let's make it, instead of it being wood siding.

120

Maybe we want to make it stucco.

121

So, I'm just going to type stucco and beige.

122

And let's give that an inch and a quarter setting.

123

So I just type 1.25 and forward slash.

124

And I have an inch and a quarter.

125

And let's say OK.

126

And there you go.

127

You can see that it's adjusting that.

128

But I'm seeing one thing that is happening with this wall.

129

What I'm noticing

130

is that it's being pushed back from the slab.

131

And it's using that reference line on the edge there.

132

And I don't know if that's exactly what I want.

133

So, let me go back to the composites.

134

And let me just check one thing.

135

So go to options and composites.

136

And so what's happened is when I duplicated those settings

137

or when I inserted skins above it, I didn't change this.

138

And so, each of these elements above it,

139

(indistinct) think it's a core, when it's not.

140

Really, these elements are other things than the core.

141

So, this is an other.

142

This is the core.

143

And so, it wants me to make adjustments from the outside in.

144

So I want to make this the finish.

145

I'm going to make this an other.

146

I'll make this an other.

147

And now I have one core and this internal buildup is other

148

and then I have two finishes.

149

So now let me push OK.

150

And what it does is it pushes the edge of that core

151

back out so that it meets or aligns with the slab.

152

And that's exactly what I want.

153

So that's composites.

154

I recommend looking at some of the composites

155

that ArchiCAD has already provided.

156

And you'll get an idea of how to build up your systems

157

in a way that reflects real world conditions.
