INSTRUCTOR: As I come in here, I realize that InfraWorks did not

00:17

fill in underneath the jersey barrier here in the center.

00:21

It just left a gap.

00:22

Also, in much of our design here, we

00:26

will want more than just the pavement level.

00:28

We will want different materials down below that.

00:31

So I am going to go over to my Home tab of the ribbon,

00:35

and open up my tool palette, so that I can

00:38

get to my sub-assembly tools.

00:41

And one of the things that I did InfraWorks was I

00:43

made this lane 15 feet.

00:45

And I was kind of setting up for this step

00:47

here, because I want a 12 foot wide lane.

00:51

My jersey barrier is 3 feet to the right, 3 feet to the left.

00:54

So if I select all of these sub-assembly parts,

00:59

right-click and go to Move To, I can

01:02

select on the assembly marker, that line that

01:05

marks the center of it, and move it over.

01:07

And that way the lane is now underneath the barrier

01:11

that is in the center.

01:12

I'm going to repeat those steps for the left-hand side.

01:15

Just right-click, move to select the assembly, and drop that in.

01:21

Now, I'm also going to go over to our tool palette

01:24

and pick the LaneSuperelevationAOR.

01:29

Come in and make sure, first of all, our lanes--

01:32

I'm going to make this lane 15 feet

01:34

to mirror what I have here.

01:36

But now I'm also going to give myself pavement depth.

01:39

I'm going to four inches on top,

01:44

of base depth, and

01:47

I am not working with an AOR here,

01:50

in this case, for super elevations.

01:53

So I'm going to turn the potential pivot off.

01:57

And this first lane, the inside point

01:59

will be Crown and the outside point will be Edge of Lane.

02:02

I'm going to select this dropdown

02:04

and choose Edge of Lane.

02:05

Now, as I come in here generally in Civil 3D,

02:09

you would be adding this to the area.

02:11

I want to replace a part that's there

02:14

with this new definition, this new dimension.

02:17

I'll right-click and choose Replace as an option,

02:21

select this lane and replace that.

02:23

Now I'm going to hit Enter, and it goes back

02:26

into the replace function.

02:27

I'll select on the left-hand center lane,

02:30

and that drops that in.

02:32

I'm going to hit Escape once.

02:34

I'm going to come back over here and make

02:36

this 12 feet, because these lanes are 12 feet.

02:38

I do have to reset these.

02:46

And actually, this one, the inside point, I'm going to say

02:49

is Edge of Lane, and the outside point is Edge of Pavement.

02:52

So I will do an 'r' for replace.

02:54

I did right-click before, but you

02:56

can do r for replace here, select this lane,

03:01

and over here I'll hit Enter to restart the command

03:05

and drop that in there.

03:08

Now, technically, this is a shoulder

03:10

but I am going to use that same LaneSuperelevation.

03:14

I'm going to make it a 5 foot width,

03:16

at a 5% slope, and the same depths

03:23

that I did for the lanes.

03:28

And I am going to give it a [? nun ?] point in the center

03:31

there.

03:31

And again, I'll type r at the command line,

03:35

select that, and Enter again, select that lane,

03:40

and drop that in.

03:42

I can't express how important the simplicity of that

03:47

is, being able to move from an InfraWorks component roadway

03:52

into Civil 3D and make quick adjustments to rebuild

03:56

the roadway.

03:57

We basically have built the alignment, the profile, and now

04:00

the assembly for our roadway from our preliminary design

04:05

discussions with our road designer

04:07

and our bridge designer, and brought it in here

04:10

and very quickly turned it around to something

04:13

that we can build in for our roadway to our bridge.

04:17

I'll select on my corridor, go to Rebuild Corridor,

04:22

and now all of that information is being added in.

04:25

I am going to have to reassign the daylights.

04:28

I forgot that that is going to wait for me there.

04:32

So I'm going to move over here to the targets

04:35

for the first region and pick the existing ground.

04:40

I'll pick the target area for the third region

04:44

and pick the existing ground.

04:45

I don't want to do the middle region because that

04:47

is the bridge way and we don't want

04:48

daylight going down to the valley floor

04:52

from that location.

04:53

So I say, OK, rebuild that corridor,

04:58

and it's going to rebuild that and give us the daylights

05:01

out to the sides again.

05:02

I'm going to close the assembly out there, and hit Escape

05:06

to let go of that roadway.
