Add labels to profile views and alignments

00:06

In this video, we're going to discuss the different types of labels associated with alignments and profiles.

00:12

So in order to talk about the labels that we're going to be using for alignments and profiles,

00:17

first, we need to navigate to the Annotation tab and then click on the Add Labels button.

00:23

Once you've done that, we're going to dropdown our feature, first to alignments.

00:27

Inside of alignments, there are multiple different label types you have.

00:30

The types you have are station offset-fixed point, station offset, single segment, multiple segment,

00:35

point of intersection, and multiple points of intersection.

00:38

So what I'm going to go ahead and do is I'm going to do a multiple segment and a single point of intersection.

00:44

In the next video, we're going to talk about station offsets, the difference between station offset-fixed point, station offset.

00:50

I'll go ahead and place one station offset fixed point as well, so that we can talk about how these relate to our alignments.

00:56

So I'm going to start with station offset-fixed point.

00:58

You have this station offset label style, I'm going to go ahead and select station offset and coordinates.

01:05

And then I'm going to leave this marker style as basic circle with cross.

01:10

I'm going to go ahead and click "Add",

01:12

and Civil 3D is going to now ask me to select the alignment that I want to place this label to be associated with.

01:17

I'm going to select my center line alignment,

01:19

and then what Civil 3D is now going to ask me is to select the location of the point that I want to place a station and offset label for.

01:27

So what I'm going to do is I'm going to place it out here into this Property 22, and then I'm going to hit "Escape" to get out of that label command.

01:36

So what you'll see here is we have a label, and if I've got it into a dragged state, it'll be more easy to read.

01:43

You'll see that it tells us the alignment name, the station, the offset, and then the location of that point.

01:50

So moving on from here, we're going to go ahead and place a multiple segment labels,

01:56

so that we can label the entire alignment in one fell swoop, instead of doing single segments one at a time.

02:03

So I'm going to go ahead and display my label for my line style as a line label style of bearing over distance.

02:12

I'm going to have my curve settings for delta over length and radius, and then I'm going to have my spiral settings as length station and A value.

02:21

But we don't have any spirals, so we don't need to worry about that.

02:24

I'm going to go ahead and click "Add" and then Civil 3D is going to ask me to specify the alignment that I want these labels to be placed on.

02:31

I'm going to select my main alignment and you'll see that if I zoom out, I have multiple alignment labels placed,

02:37

I have curves and line segments, all placed along my alignment here.

02:43

So moving on from there, I'm going to go ahead and place a single point of intersection, and I'm going to leave it as just the station label style.

02:51

So I'm going to go ahead and click "Add" and what Civil 3D is going to ask me to do is to select the tangent in or curve of PI to label.

02:60

So if I selected this curve, it would choose the PI associated with that curve or I can select the tangent associated with this PI.

03:07

So I'm going to select this tangent and then it pulls a label out of that PI.

03:10

So I'm going to go ahead and close.

03:12

And now we're going to talk about how each of these labels interacts with our alignment.

03:17

So in the case of VPI and the segment labels, these are linked to a specific location in the alignment.

03:26

So if you make a modification to that alignment, those labels will move and change based on the modifications that are made to that drawing.

03:33

So if I go ahead and I select this tangent triangle here and I select this grip edit here and I move my whole alignment out,

03:45

what you'll notice is that my label for my curve changes, my segment labels change, and my PI station northing and easting label also moves with it.

03:56

So if I then go look at, I'm going to go ahead and do "Ctrl+z" to move my alignment back.

04:02

If I go look at my station offset label and I do that same movement, you're going to notice that the northing and easting is not going to change,

04:12

but my station and my offset are going to change because what is happening here is this label is a label that is looking to the alignment,

04:21

but it's a label of information based on this specific space in the drawing.

04:27

So I have this point and what its relation is to the alignment, but it will not modify that location.

04:33

So I'm going to go ahead and move my alignment out.

04:35

And what you'll notice is the station and the offset changed, but the northing and easting never changed.

04:42

Moving on from here, I'm going to go back into the Add Labels, I'm going to dropdown and I'm going to select from my features, my Profile View.

04:50

You'll notice inside of here, there's no option for a profile, it's just profile view.

04:57

So we're going to go ahead and label our profile view.

04:60

We're going to navigate over to our profile view.

05:02

And the important thing to note about all of these labels inside of this are that we are labeling the profile view itself,

05:09

we aren't labeling anything associated to our actual profiles inside of that profile view.

05:15

So if there's an edit made to the profiles inside of the profile view, these labels will not update themselves based on those changes.

05:23

So we'll place a couple of these and then I'll show you an example by moving our profile.

05:29

So I'm going to go ahead and dropdown and choose station and elevation,

05:32

and I'm going choose the station and elevation label style, and then I'm going to leave my marker style as basic.

05:38

I'm going to click "Add" and Civil 3D is going to say, select a profile view.

05:41

I'm going to select this profile view and then I'm going to find a point, I'm going to label what the midpoint of this profile is.

05:51

So I pick the midpoint for the station, now I'm going to pick the midpoint again for the elevation.

05:57

And I have a station elevation label that tells me that the midpoint of my profile is at station,

06:04

or the midpoint of this tangent section of my profile is station 7+71.98 and an elevation of 191.98.

06:12

Now if I go ahead and I do a depth, I can do depths on certain objects inside of this profile view window.

06:20

So if I drop a line and I trim this line out, and I do a depth command and add it in,

06:29

and I select the profile view window that I want to work in and I set this point and this point,

06:38

then what Civil 3D is going return is really what is the distance between that point and this point,

06:43

because what I can do is I can take this and I can go over here, and I can go up here.

06:48

And so it has retained the depth, so I can find the depth.

06:56

Basically it's just the y-component of this triangle that would be created.

07:00

So this is the horizontal, this is the vertical, and this is returning my vertical component of that.

07:06

But what you'll notice is, so if I'm supposedly labeling between this profile and this alignment, or this profile and this profile,

07:14

when I modify these, this is going to stay exactly where it is.

07:18

Again, you also have an option for labeling projections.

07:22

We don't have any projections in our profile right now, so I can't label one.

07:25

But what I'm going to go ahead and do is I'm going to take this profile,

07:29

I'm going to grab this point of vertical intersection and I'm going to drag it up.

07:35

So clearly, those two labels are no longer residing on that profile.

07:41

And so with our alignments, all of our labels would've updated because these aren't related to a profile,

07:46

they're related to a profile view window, they're not going to auto-update.

07:50

So I'm going go ahead and move it, and you'll notice I still have a station, elevation label here and a depth label here,

07:57

but they don't actually apply to anything.

07:58

So I'm going to go ahead and hit "z" so I don't have that modification to my profile.

08:02

And then I'm going to go ahead and delete out these labels,

08:07

because they don't mean anything to specifically anything that I'm trying to call at my profile.
