- [Instructor] All right. Let's talk about the Mesh Tool.

2

So the Mesh Tool can be found in your toolbox over here.

3

And so let's double-click and kind of look at what this is.

4

So the mesh is a multi-faceted element

5

that can represent the ground plane

6

and you can use it to kind of delineate

7

the surface of your project.

8

And it can be shown in a couple of different ways

9

so you can have a solid internally

10

and a skirt around it and the surface of it.

11

It can just have the skirt and the surface,

12

or it can just have the surface.

13

And you can change what kind of material it's made out of,

14

and you can change the location of where it is.

15

Sometimes I put this on a story

16

that's below the first story.

17

You'll start to figure that out

18

once you get a little bit more into this.

19

So if I do put it on a story that's below my first floor

20

I will just have it show up on the story above it

21

and we can adjust what the surfaces are of that mesh.

22

And then finally, we can adjust the layer.

23

So I'm going to put this on L Site 3D and say okay.

24

And because that layer is off, right when I click,

25

it's going to ask me "Do you want to show that layer

26

"or do you want to choose another layer?"

27

So I'm going to say "Show that layer."

28

And I can create this in a couple of different ways.

29

I can create it by the poly method

30

that we've been using before,

31

I can do just a rectilinear method

32

and then I can also do it so that it's creating the slopes

33

through its own settings.

34

And so what I'm going to do,

35

I'm going to use a technique that we've been using before.

36

This just saves me some time.

37

I'm just going to push the spacebar.

38

I have the tool selected.

39

I have the settings that I want,

40

and I'm just going to click on the edge of the zone

41

that I created earlier.

42

And now I have this mesh

43

but what I really want to do is I'm going to hide this zone.

44

So here's the mesh

45

and what I'm going to do is I want to create

46

the actual mesh of the site.

47

So I'm just turning back on the trace

48

of the site survey that we have

49

and what I could do to create this is I'm going to

50

take my pen line tool

51

and I'm just going to choose a different layer for this.

52

So let's put this on the drafting layer,

53

'cause I'm just using this to

54

kind of create some information.

55

So I could do it this way.

56

So I can go around and kind of click through

57

and get like kind of a best fit.

58

And these are the contours that I'm following.

59

So I could do it that way.

60

Another way I could do it is I'm going to go

61

to the survey itself.

62

So I'm going to use this changed my reference.

63

So now I'm going to go back to the reference to this.

64

And so I'm going to select that but I need to ungroup these.

65

And so I'm going to take these groupings,

66

I'm going to suspend groups.

67

That's leaving me with just this survey line.

68

And what I'm going to do is I'm going to hide others

69

so it leaves me with most of the surveys,

70

not sure what that line is,

71

but I'm not worried about it right now.

72

And then I'm going to invert my survey

73

or I'm going to go back to the floor plan.

74

And so nothing's showing up.

75

So I just want to turn on

76

the mesh itself that I was working with.

77

So that was found on L Sites,

78

so let me just turn that one on.

79

And so there's the outline of our site.

80

And what I can do is if I push the alter option button

81

and click on the mesh, that highlights the mesh.

82

And so this allows me to do something really unique.

83

It allows me to push the spacebar

84

and depending on what I'm selecting,

85

so I'm going to do one thing before I do that.

86

I'm going to just remove all my guidelines.

87

So I can go in here and click on that line

88

that's the reference

89

and I'm just going to save, Fit to User Ridges and say okay.

90

And so that's giving me the contours.

91

And so if I could do that again, I can go through

92

and it's going to allow me to quickly go through this.

93

The only caveat to this is that

94

sometimes when things like this happen,

95

it can mess you up a little bit.

96

So I'm just going to go back, just Command + Z or Control + Z,

97

and I'm going to show you a different way to do this.

98

So I still have the tool selected

99

and so if I wanted to start to follow these contours

100

I can click the line and start to trace it around

101

and that'll allow me to follow the contours.

102

Once you start to get comfortable with this

103

now you need to elevate the contours.

104

And so I fit to user ridges.

105

And so let's look at this look closer.

106

So this is saying it's at 97 feet

107

and so what's my lowest one?

108

So these are at, this is 97. This looks like it's 96.

109

So 96, 95, 94, 93 92

110

and it looks like there's like a 91 there.

111

So what I can do is I can elevate this.

112

So this is one, two, three, four, five, six feet higher.

113

So I grab that node

114

and if I click the Z button, elevate mesh,

115

and I say apply to all of the pieces of that line

116

or everything that's connected to that one contour,

117

I can raise that 6 feet

118

and then I'm going to raise this one

119

and it's already selected in that elevate.

120

So just put 7 feet and let's just make this 8 feet

121

and this one is 8 feet

122

because it's not connected through around that.

123

And let's make this 10 feet.

124

So let's look at that in 3D.

125

And so show selection in 3D, I just right-click on it.

126

And you can see pretty quickly here,

127

I can start to get a little bit of a contour or a Topo map.

128

And so it looks like one of these lines didn't really get

129

to the right height.

130

So let's just elevate that and so I'm going to elevate it

131

and I can do it individually.

132

And then I can slide over

133

and start to fix the little anomalies that are happening.

134

So it looks like there's a few extra points

135

that got created there.

136

So that's one thing to be cognizant of

137

as you start to create these meshes

138

but this gives you a good idea

139

of how quickly you can create a mesh.

140

There are a few other ways,

141

and we'll talk about that later in the course,

142

how you can quickly bring in a mesh.
