Edit grading groups

00:04

We're now going to use the grading creation tools to edit our grading groups.

00:09

We've created grading groups for each of our house slabs.

00:14

If I review the grading surface for house seven,

00:18

you can see that it has created a surface across the whole of the slab

00:23

including a margin around it.

00:27

However,

00:28

if I review has four,

00:30

we can see that there is a hole where the foundation slab should be.

00:35

We need to fix this by adding some grading to the group

00:40

from the home tab create design panel,

00:43

click on grading and select the grading creation tools

00:48

in the tool bar. Ensure the site is set to house plots

00:51

and set the group to house four

00:55

from the crate grading, pull down slit crate infill

01:01

in the model. Pick a point in the middle of the house floor slab,

01:05

you'll see that it places a grading marker in the center of the area

01:09

to show that grading has been created.

01:13

Now, if we review the house for surface,

01:16

we can see that it is filled in the area of upgrading feature light.

01:23

Now let's review the pond grading

01:26

looking at the pond contours. We can see that they overlap the road surface.

01:31

Clearly, we need to make sure the pond grading doesn't interfere with the road.

01:37

We can do this by editing the gradient of the embankment nearest the road,

01:42

open the grading creation tools and set the sight to balancing pond

01:46

and the grading group to pond.

01:49

Click on the edit grading, pull down and select delete grading

01:55

in the model. Pick a point in the outside embankment grading to delete it

02:02

from the grading criteria. Choose grade to surface

02:06

and then click on great grading.

02:10

Pick the outside grading feature line

02:14

on the command line for apply to entire length slate. Note

02:19

it will then prompt for a start point.

02:22

Select a point on the embankment area at the south east corner as shown

02:26

and press enter to accept the station value,

02:29

then move to the west side of the pond and pick a similar position and press

02:36

for the cut format. Select slope

02:39

then type three for a one in three slope.

02:43

Repeat this for the fill format.

02:46

You'll see a fan shape of grading has been created on the north side of the pond

02:51

from the tool bar, select crate grading again

02:54

and picked the same feature line

02:57

for the start point. Pick the end of the southern straight segment on the left

03:01

and press enter,

03:04

pick the other end of the strait for the end point,

03:09

set the cup format to slope

03:11

and enter two for a one in two slope

03:15

then repeat this for the fill format.

03:18

Now, we need to fill in the gaps between these two gradings

03:23

on the crate grading, pull down s select crate transition,

03:28

pick the feature line again. And then for the location,

03:32

pick a point between the two gratings.

03:35

This will create a transition between the one in three and one in two slopes.

03:40

Repeat this for the other side of the pond

03:44

for us escape to end the command and update the grading.

03:48

Now,

03:48

review the pond surface in the object viewer to see the result of the grading edits.

03:54

From this example,

03:56

we can see that the grading group is made up of

03:57

individual gradings that we can adjust to suit our design constraints.

04:03

Editing a grading updates the entire grading group.
