Perform a surface analysis

00:06

Now that we've specified our parameters for our slope analysis,

00:10

we're going to go ahead and go into our surface display settings and turn on that analysis so that it actually shows up inside of our drawing.

00:17

So I'm going to go ahead and go into my EG. I'm going to right click and choose Surface Properties.

00:21

Inside of Surface Properties, I'm going to navigate over to my Information tab and I'm going to go to my surface style.

00:28

I can edit the existing surface style if I want to, and turn on my slope analysis,

00:35

or I can create a new surface style and I can change it to call it Slope Analysis.

00:48

And I can go over to my display and I can make sure I have my border turned on.

00:52

And then I can turn on my slopes and I can hit "Apply" and hit "OK", and then hit "Apply" and hit "OK".

00:59

And what you'll see here is that my slope analysis has been performed.

01:03

However, when I did that slope analysis, I set my range for my lower end too wide.

01:12

Most of my slopes, as you could have seen from my last analysis when we applied the parameters, had everything in the range between 0% and 6%.

01:24

So what you see here is that a majority of them fall in between the 0% and 10%.

01:32

And that's defined under our Surface Properties, under our Analysis tab, if we go to slopes, you'll see I have at 0-10, 10-50.

01:42

And so most of the colors in here are in my 0-10 range, and I have a few in the 10-50.

01:48

So if I went to 5 and I hit the down arrow again, it would redistribute this information and it would change these ranges,

01:56

so that I get a better gradation of analyses inside of my specific surface.

02:01

So it's tailoring these numbers specifically to that surface.

02:05

So what I'm going to go ahead and do is I'm going to apply this now and you can see how if you did an incorrect range for your analysis,

02:14

then you can go ahead and apply it back and have a better range.

02:18

But this may not be a problem for you if you, for some reason, needed to have showing areas that were less than 10%,

02:26

and you didn't want to have a large gradation of ranges, then maybe you want to leave it as this.

02:32

But I'm just going to apply this so that you can see how it changes based on changing the range values.
