- [Instructor] All right, welcome back.

2

So we're going to talk about the slab tool now.

3

So the slab tool is similar to the fill tool

4

in a lot of ways, especially in the floor plan view,

5

but let's go into that setting.

6

So in the toolbox, I just double-click

7

on this little flat plane object and that's the slab tool.

8

So when I open it up, it gives me a few different options.

9

So we have the composite style or the structure of the slab.

10

And so we have either basic

11

which means that there is no composite associated with it.

12

And so that means that there's no different materials

13

that are sandwiched together

14

to kind of make the element itself.

15

Or we can select the composite

16

which is the sandwich of different materials

17

that make it up.

18

I'm going to use the composite.

19

So let's select the floor generic 10 inch F01.

20

And you can also select where the reference plane is.

21

So that means like if you're placing this

22

onto the first floor

23

and zero is the reference plane

24

then the top of that slab will be at zero,

25

versus if you select the bottom of that reference plane

26

then the bottom of that slab will be at zero.

27

Or you can select the top of the structure of the slab.

28

So if you had like carpet or some other material

29

that wasn't actually something that needed to be at zero

30

but your not finished floor

31

but your slab or your wood deck was at zero,

32

then you might want to choose this.

33

I'm going to choose this one just because for me

34

that makes the most sense.

35

I'm not measuring necessarily the finished floor zero.

36

I'm probably going to manage to structure

37

as the core of the structure at zero.

38

And then you can select which floor it goes on.

39

So if you wanted it to be on a different floor

40

than the one you're working on for some reason

41

you could select there.

42

And then you could also adjust the height.

43

So if you wanted it to be two feet above your current floor,

44

so say if you had a mezzanine

45

or some transition in the horizontal plane,

46

then you could adjust it there.

47

And then you can also adjust how it shows up.

48

So if you want it to show up on multiple different stories

49

even though its home story is the first floor

50

you could do that here.

51

So you could say show on all stories.

52

So for instance, again, if you had a mezzanine

53

or some interstitial floor that was between two floors

54

but it needed to show up on three different floors

55

then you could do that here.

56

And then you can override the cut fill.

57

So if you wanted it to look differently

58

than what the element itself

59

or the building materials were showing, you'd do that here.

60

You can also give it a cover fill.

61

If you want it to show up with concrete or carpet

62

or something of that nature, you could do that here.

63

So for now I think what I'll do is I'll choose concr,

64

well, it's actually wood.

65

So since it is wood, it would be a little confusing.

66

I'm just going to not use a cover fill at this moment.

67

I'm going to deselect that.

68

And then it already, with the model,

69

the surface elements itself

70

you can adjust what the top surface is,

71

you can adjust what the side surface is

72

or the bottom surface is.

73

So that's helpful if you're creating a rendering

74

and you wanted it to show up as carpet

75

but it was actually this generic floor material.

76

So it just gives you a little bit more options.

77

Then you can select the layer.

78

So I'm going to choose, I think this makes sense.

79

So it is a floor, so I'm going to choose floor

80

and then we'll say okay.

81

Up here it has a few different geometry methods.

82

So you can use the polygon method,

83

which we talked about before.

84

You can use a rectilinear construction method

85

or you can use an angular rectilinear method.

86

I'm going to use the polygon method

87

because I don't think that this is a perfect rectangle.

88

And again, similar to what we had worked on before

89

with the fill and the zone, we can just go over

90

and I can select my space bar

91

and I can use the space bar or the magic wand,

92

and I can click and let's see here.

93

So there it is.

94

Just by selecting, using the magic wand

95

by pushing the space bar, I'm able to create that slab.

96

And let's look at it in 3D.

97

So if I go to view and let's look at show all in 3D,

98

and there it is.

99

So that is the slab that we just created.

100

So let's go back to the floor plan.

101

So if I just click up here and go back to the floor plan.

102

So that works, let's create a slab for this sidewalk.

103

So I already have my slab tool selected, or I did.

104

And so let's put this on a actual slab instead of a floor

105

'cause that's more appropriate.

106

And now let's change it from this composite

107

and let's just choose a simple volume

108

and let's just give it a concrete site work.

109

So I'm just going to choose the building material

110

concrete site work, and I'm going to do the polygonal method

111

but I could also just use the space bar.

112

And one thing to be cognizant of

113

is if you push the space bar and you see

114

that blue line around,

115

that is where it's to create the slab.

116

But if I move it up, I'm still holding the space bar,

117

I can see that if I get on the edge

118

that it's going to make a slab

119

around the entire fill itself versus inside of this area

120

because this line here is causing it to want to stop.

121

So let's just quickly make that sidewalk.

122

So I'm clicking each of the edges

123

or the nodes or the intersections there.

124

And I'm just going to make a mistake on purpose here.

125

Whoops, I just, nope,

126

that's not exactly what I wanted to do.

127

So what do I do to get back without losing

128

all of the work that I just did?

129

I just push the delete button and it allows me

130

to go back one node.

131

And maybe I made two mistakes.

132

I could push delete again and I've just gone back again.

133

So very useful, very helpful.

134

Especially when you're doing things

135

that have lots of clicks to execute.

136

And now I can just finish that and click and there we go.

137

So let's look at that again in 3D.

138

So if I go to view, elements in 3D view,

139

and then I go show all in 3D

140

and now I have my sidewalk and I have my first floor plate.

141

So that's slabs.
