Work in the profile grid view

00:05

In this video, we're going to get into the last editing method in the Profile Creation toolbar.

00:10

So again, we're going to navigate into the Profile Creation toolbar by selecting our Profile and selecting Geometry Editor.

00:16

Inside of here, we're going to go ahead and look at the profile grid view for our design profile.

00:24

So in order to populate that window, you're going to go over here to the Profile Grid View, you're going to select it.

00:29

And what you have in here is you have the information for all of your PVIs and any of the curves associated with those PVIs.

00:37

So we have stations, elevations, grades, and profile curve lengths, K values, and curve radiuses.

00:45

We can modify any of these to give us a better design profile and better mimic what we want to have going on inside of our drawing here.

00:54

So what we're going to do first is we're going to go ahead and modify some of the grades.

01:00

So I'm going to make the assumption in my Profile View window that I want that design profile to be coming off the road at -1.5%.

01:13

So I'm going to modify this to -1.5%,

01:15

and so when I update that, you're going to see this PVI dropped because I changed the grade out from here and into this PVI.

01:22

So moving on from there, I'm going to say that I don't want my road to be at a 0.1% slope.

01:27

I probably want to have it at a minimum of 1%.

01:30

So I'm going to go ahead and change this 0.1% to 1%.

01:33

So I'm going to hit "Enter" in there.

01:35

Then what I'm going to see happening here is I'm going to see a pretty big hump in here,

01:39

so maybe 1% is not the best choice, maybe I want to go ahead and go with a 0.8%.

01:46

So I'm going to go ahead and go 0.8% and hit "Enter".

01:49

It's getting a little closer, still a little high, but I'm ok with that.

01:53

So I'll go ahead and leave it there.

01:55

Maybe I want to go to a 0.5% knowing that I have got a depression here and the drainage will work out ok.

02:03

So I'll go ahead and leave at as 0.5% and move on to the next one.

02:15

so I'll go ahead and put -2% in there and see how that affects my vertical intersection right here.

02:23

And then from there, what you can see is I want to maintain this point here tying to the end point on my surface.

02:29

So I don't want to modify my grade coming out of my second to last PVI.

02:36

So if I wasn't happy with this and I wanted to modify this grade here, this 1.34%, I would go ahead and modify this grade right here.

02:44

So the next options that we have available to us, if you wanted to change some profile curve length information, which I do,

03:02

That looks a little bit better, it's bringing my profile down a little bit more.

03:06

Maybe you want to even go test out and see if 150 foot curve looks good.

03:10

And so I've now placed a 150 foot curve, we're getting even closer to mimicking the existing conditions.

03:15

I think I'm going to go ahead and leave it at 150 foot vertical curve.
