Create a corridor for your 3D road model in Civil 3D, and create a surface for the road.
Transcript
00:03
A Civil 3D corridor combines horizontal alignments, vertical profiles,
00:08
and cross-sectional assemblies to create a 3D representation of your project.
00:14
This enables you to visualize the entire design
00:17
and ensure that all components work together seamlessly.
00:21
Advantages to corridors include integrated design and visualization,
00:26
dynamic and parametric design capabilities,
00:29
and accurate earthwork calculations.
00:32
You can also use a corridor to easily create a surface for your model.
00:37
To create a corridor for a 3D road model in Civil 3D,
00:42
first, you must have a horizontal alignment, a vertical profile,
00:46
and an assembly already designed, as in the drawing for this example.
00:51
From the ribbon, Home tab, Create Design panel, expand Corridor, and select Corridor.
00:59
In the Create Corridor dialog, specify a Name, add a Description,
01:05
choose the Corridor style, and select the Code set style.
01:09
By default, Alignment, Profile, and Assembly are all set to None.
01:15
To select an alignment, in the Alignment column, click the Select icon.
01:21
You are prompted to pick an alignment in the drawing.
01:25
Since the selected alignment has an associated profile, in the Select Profile list,
01:30
select the appropriate profile.
01:34
Back in the table, click Select in the Assembly column.
01:38
In the drawing, zoom in to locate the marker, then click it to select the assembly.
01:45
Your alignment, profile, and assembly are now set.
01:50
Click OK.
01:52
The Baseline and Region Parameters dialog opens,
01:56
where you can set the targets for your corridor.
01:59
Note that in this example, the selected assembly has daylight lines that need to know what to target,
02:05
so there is an exclamation point indicating that this region is out of date.
02:10
To resolve this issue, select Set all Targets.
02:14
The Target Mapping dialog appears, allowing you to set Offset, Elevation, and Surface targets.
02:21
From the Surface tab, set the target to the existing ground, or EG,
02:26
for both the right and left sides of the Daylight Basin subassembly.
02:32
For each Target Surface Row, expand the Target drop-down and select EG.
02:38
Click OK, then click OK again to rebuild the corridor.
02:44
If prompted that the corridor is out of date, select Rebuild the corridor.
02:50
In the drawing, notice that the corridor model now overlays the alignment.
02:56
To view the model in 3D, select the corridor, then right-click and select Object Viewer.
03:04
Review the 3D model and 2D line work, and then close the Object Viewer.
03:12
You currently have a road model, but with no surface,
03:16
so the next step is to create a surface from the corridor.
03:21
In the drawing, select the corridor model.
03:24
Then, on the contextual ribbon, in the Modify Corridor panel, click Corridor Surfaces.
03:31
In the Corridor Surfaces dialog, expand the Specify code drop-down to choose an option for creating the surface.
03:39
For example, if you want it to represent where you need to grade down to
03:43
before building up the road with base and subbase materials,
03:47
choose Datum elevation.
03:49
Here, you just want the top surface, so select Top.
03:54
Click Create a Corridor Surface,
03:56
and then click Add surface item to add the chosen codes to the surface.
04:02
Click OK.
04:04
Back in the drawing, notice that since the road in this example is U-shaped,
04:08
there is an issue with the contours crossing through the middle area.
04:12
To avoid this, return to the Corridor Surface dialog.
04:17
On the Boundaries tab, right-click the boundary and select Add corridor extents as boundary, then click OK.
04:27
In the confirmation dialog, select Rebuild the corridor.
04:32
As you can see, the contours are now corrected.
04:37
Select the surface and open the Object Viewer
04:40
again to see the surface and corridor model together.
04:43
Now you can combine a horizontal alignment, a vertical profile,
04:48
and a cross-sectional assembly to create a 3D corridor model in Civil 3D.
