Edit layout profiles

00:05

In this video, we're going to talk about editing layout profiles using the profile creation tool.

00:11

In order to get back into the profile creation tool for our design profile,

00:15

what we need to do is we need to select the design profile that we're working with,

00:19

and go up to the contextual ribbon bar and click on the Geometry Editor.

00:23

Inside of the Geometry Editor, we're going to see that our Profile Layout Tools pops back up,

00:28

and it displays that we're working inside of our Dev-Prof again.

00:33

We already talked about the first half of the profile layout tools, what we're going to be dealing with now is this second part.

00:40

Specifically, the placement of PVIs using components or insertion of PVIs using the tabular summary.

00:48

So that option, if you select it, what you'll notice is that we get a option for inserting PVIs using a station and elevation number.

00:58

You can also if you want to place a curve because the placement of a PVI is just the two tangents coming into that point.

01:06

The creation of a curve would be selecting your curve option and then telling station, elevation, and curve length.

01:13

So I'm going to go ahead and do a station equation for a parabolic curve and we're going to place it in and see what happens.

01:22

So I'm going to give a station of 7+50, I'm going to give an elevation of 190, and I'm going to give a curve length of 50 feet.

01:30

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

01:31

And what you'll see happen here is that I've now added in a new point of vertical intersection with a parabolic curve between these two points here.

01:40

And you'll see the information showing that the length of that curve is 50 feet, the station is 7+50, and the elevation of the PVI is 190.

01:49

Moving on from there, you can raise or lower your PVIs using this button.

01:55

And then you can copy profiles using this button.

01:58

Moving on into the next section, this is where you get a majority of your editing done based on certain parameters.

02:05

The two parameters that you can edit profiles in on the toolbar here is PVI based editing and entity based editing.

02:13

So, with PVI based editing, you're going to be selecting the PVI that you want to modify, and then you will change information on it.

02:21

So I'm going to go ahead and select PVI.

02:25

And then what happens is the Profile Layout Parameters window shows up.

02:29

Sometimes when you're working inside of Civil 3D, if you close this window and you select your PVI button again, that window may not show back up.

02:40

Also it doesn't show up sometimes after you selected it and then clicked near the PVI you want to edit.

02:45

If this window doesn't show up and you feel like the drawing has been locked out, it may be as simple as having to click this window button again.

02:54

So if it's not displaying, you just click it and it will display again and then you can get into your PVI or entity based editing again.

03:02

So inside of this Profile Layout Parameters window, what you can have is you have the information for that one point.

03:11

So we have a grade in which is -2.33%, we have a grade out which is 0.81%.

03:18

We have a PVI Station which is contained right here, 4+97.28.

03:24

And then we have a PVI elevation which is 187.943.

03:28

When you're editing PVIs, what you have to understand is that if you edit the station or the elevation, you are going to be modifying the point,

03:38

and you will retain connection to the tailing PVI and the leading PVI.

03:44

If you modify the grade in or the grade out, you will retain your PVI's station and elevation,

03:50

and you will be modifying either in the case of grade in, you'll be modifying the tailing PVI.

03:56

And in the case of grade out, you will be modifying the leading PVI.

04:00

Moving on from there, I'm going to go ahead and, just as an example, change my grade in.

04:06

And so what you'll see happen is we will retain our station and elevation for our PVI.

04:11

And this PVI will end up getting lowered, because I'm going to modify my grade in to -1.5.

04:16

I'm going to hit "Enter" and what you see is the PVI lowered, our grid has changed, but our labels haven't updated.

04:23

What I have to do is hit "Enter" again to accept that change, and now all the labels update themselves.

04:28

Moving on from there, we can get into entity based modifying and so we can select our sub-entity.

04:35

So I'm going to select my sub-entity, I'm going to go into this curve here.

04:39

And what I'm going to go ahead and do is I am going to go into this and I'm going to change my curve length.

04:45

So my curve length, I'm going to change to 75.

04:49

And then from there, you'll see what happens to the change is it kind of widens the arc of this vertical curve,

04:58

and all of the rest of the information generally stays about the same, I believe there are a couple of objects changed within here.

05:07

But for the most part, your PVI station stays the same, your PVI elevation stays the same.

05:11

All your grades should remain the same.

05:13

You just change your curve radius and your K value.

05:17

You can also get additional information about your curve from here.

05:20

So you can get your passing sight distance, your stopping sight distance,

05:24

your grade in, your grade out, your PVI station, PVI elevation, and all of that information.

05:29

You just can't modify the ones that are gray.

05:31

So moving on from here, the last option that we're going to talk about is deleting objects.

05:37

So if you have a sub-entity that you don't like, that you don't want to have in your drawing anymore,

05:43

you can delete that sub-entity by going into the delete sub-entity option.

05:48

I'm going to go ahead and select it and then I'm going to navigate to this curve that I have here and I'm going to delete it.

05:53

And so when you click on it, it deletes that one sub-entity.

05:56

So you can delete individual pieces and parts of your profile and then draw them back in later.

06:02

I'm also going to delete this new PVI that we created by clicking delete PVI and then clicking near it and hitting "Enter" to accept that.
