Create a finished ground model

00:03

We have created feature lines for our house positions and set their elevations.

00:09

We have also added feature lines from the adjacent road corridors

00:14

at the back of the highway boundaries.

00:19

Additional feature lines have been added to enable us to control the site levels

00:23

and we can use these to modify the grades if we need to.

00:28

We're going to create a surface from these features that

00:30

we can then add to a finished ground model.

00:33

We can use the finished ground model to

00:36

design our drainage and utilities for the site

00:40

in prospector. Right, click on the surfaces collection and choose create surface.

00:45

We'll call this surface plot grading

00:49

for the surface style,

00:51

use contours, 1 ft and 5 ft design,

00:56

expand the surfaces collection

00:58

and expand the plot grading surface and its definition.

01:03

We want to add our feature lines to the surface as brake lines

01:07

but picking them in the drawing is tedious.

01:11

The feature lines all belong to the house plots site.

01:15

So expand the site,

01:16

select feature lines and right click

01:21

on the right click menu. There are two select options.

01:24

Use the first one to select all of the feature lines in the site,

01:29

scroll back up to the plot grading surface

01:31

and right click on brake lines and choose at

01:35

these will be standard brake lines as they're in 3d.

01:39

We don't need to weed or supplement the vertices on these brake lines.

01:43

Click OK. To add them to the surface.

01:47

You can see in the model that the surface has been created.

01:51

If we look at this in the object viewer,

01:53

you can see the surface is very flat and quite even

01:56

with no major changes in great.

02:01

We're now ready to create our finished ground surface.

02:06

We'll want to add our pond,

02:08

our road top surfaces

02:10

and our new house plot surface

02:15

in prospector select the surfaces collection

02:18

right click and choose create surface

02:23

name the surface finished ground,

02:27

use the style contours, 1 ft and 5 ft design and click. OK.

02:33

Expand the surface and its definition

02:36

right? Click on edits and choose paste surface.

02:40

We'll start by adding the existing ground.

02:43

Our design surfaces will be added on top of this,

02:48

repeat the pace surface command.

02:49

But this time select all the corridor top surfaces.

02:53

These represent the finish levels of our roads

02:57

finally paste in the pond and plot grading surfaces,

03:05

select the new finish ground surface and review it using the object viewer.

03:09

The resulting surface is the same as the existing ground

03:12

except where our design surfaces have been pasted over it.

03:19

We'll want to use the finished ground surface in other models to design upon.

03:23

So we'll create a data shortcut for it in our project.

03:28

In prospector,

03:29

select data shortcuts,

03:31

right click and choose create data shortcuts,

03:35

select the finish ground surface and click. OK.

03:41

Save the sight grading drawing and then create a new drawing

03:46

use save as

03:47

and save the new drawing

03:49

in the project design models. Folder

03:53

name the drawing, drainage desire

03:55

from the data shortcuts in prospector expand the surfaces collection

03:60

and select the finish ground surface

04:03

right. Click on it and choose create reference,

04:07

change the style of the reference surface to contour's 1 ft and 5 ft background.

04:13

Use zoom extents to see the surface.

04:18

We have now completed our site grading and have a finished ground model

04:22

that we can use to design our drainage and utilities.
