Create surface labels

00:06

In this video, we're going to create and apply spot elevation and slope labels based on our Civil 3D surface.

00:14

So to create labels for our Civil 3D surface, we're going to go to the Annotate tab in the ribbon bar,

00:19

and we're going to go to Add Labels and we are going to go to Surface and we are going to Add Surface Labels.

00:27

Under the Add Labels window, we're going to make sure we have Surface selected and we are going to first do a spot elevation label.

00:34

There are many surface elevation or surface labels that you can create.

00:38

You can create slope labels, spot elevation labels, spot elevations on a grid, contour single, contour multiple, and contour multiple at interval.

00:47

For this video, we are going to discuss spot elevations and slope labels.

00:51

So I'm going to select Spot Elevation first.

00:54

Then you have the option of what your spot elevation label style is going to be.

00:58

These label styles, you can either go with what is currently provided for inside of Civil 3D or you can create a new one.

01:07

And when you create a new label, it's just like all the other labels that we've created so far.

01:12

You have an Information tab, you have your general text information,

01:16

you have how you want it to be displayed in layout with your contents going into the content manager window,

01:22

where you select the information you want to provide for that label,

01:26

and then you can create additional components - lines, blocks, or reference text.

01:32

You can work on your dragged state and then you can find out the summary of your label style.

01:37

So I am not going to create a new label style, I'm going to use the Elevation Only,

01:42

and then you have the marker style for how you're going to display that specific point elevation label.

01:51

So I'm going to go ahead and click "Add".

01:53

I'm going to select the surface, so I can either click on the surface that I want to add the label to, or I can hit "Enter" and a list comes up.

02:01

And so I can say, I want to add a spot elevation label to my EG surface.

02:05

So I'm going to go ahead and click "OK".

02:08

Then I'm going to zoom in and I'm going to pick a spot in this flat area right here.

02:13

And as you can see, that spot elevation was placed at an elevation of 186.56.

02:19

So then I'm going to move on and we're going to talk about slope labels.

02:22

There are two types of slope labels.

02:26

And what we have available to us in the slope labels is a single-point slope label and a two-point slope label.

02:33

So what we're going to go ahead and do is we're going to choose the type of label we want to select.

02:39

Again, I'm not going to create a new one, but I am going to choose one of the ones that are available for us inside of this current drawing.

02:46

So I'm going to go with Percent slope.

02:48

I'm going to click "Add", Civil 3D is going to ask me to select a surface, I'm going to hit "Enter" and select EG.

02:54

I'm going to click "OK" and then it's going to ask me what type of slope label I want to do.

02:59

I can choose one-point or two-point.

03:00

So at first, I'm going to choose one point, so I'm going to say "o" for one-point,

03:04

and then I'm going to select a point on my surface to place that label.

03:08

And so I selected that point and it created a slope label that says negative 6.2%.

03:15

Now place another slope label and this time I'm going to select a two-point slope label.

03:20

So I'm going to select my EG surface, I'm going to hit "t" for two-point,

03:26

and then Civil 3D is going to ask me for my first point and it's going to ask me for my second point.

03:32

And so as you can see, the slope is different across these and the reason the slope is different across these is,

03:38

because what Civil 3D is doing in the single-point slope label is, it is telling me what the slope of the triangle at that point is on the surface.

03:49

And what Civil 3D is doing in the two-point label style is that it is coming up with an average slope across,

03:57

from this point elevation to this point elevation and what is the slope across that length.
