This tutorial demonstrates how to use Autodesk Civil 3D objects to build a basic corridor model.
This tutorial uses the corridor assembly that you built in the Creating an Assembly exercise.
A corridor can be used to model a variety of features, such as highways, channels, and runways. In this tutorial, you will model a residential road.
A corridor model builds on and uses various Autodesk Civil 3D objects and data, including subassemblies, assemblies, alignments, feature lines, surfaces, and profiles.
Corridor objects are created along one or more horizontal baselines by placing a 2D section (assembly) at incremental locations and creating matching slopes that reach a surface model at each incremental location.
Specify the basic corridor information
- Open Corridor-1a.dwg, which is located in the tutorials drawings folder.
- Click Home tab >> Create Design panel >> Corridor Find.
- In the Create Corridor dialog box, specify the following parameters. Alternatively, you can use the buttons to pick the objects from the drawing.
- Name: First Street
- Baseline Type: Alignment and Profile
- Alignment: First Street
Profile: Finished Grade Centerline – First Street
(Profile view grid lines removed for clarity)
Assembly: Primary Road Full Section
Target Surface: EG
Set Baseline and Region Parameters: Selected
- Click OK.
Specify the baseline and region parameters
- In the Baseline and Region Parameters dialog box, in the RG-Primary Road Full Section – (1) row, in the End Station cell, enter 0+440.00.
- In the Frequency cell, click .
- In the Frequency To Apply Assemblies dialog box, under Apply Assembly, for Along Curves, verify that At An Increment is selected.
- For Curve Increment, enter 3.000. Click OK.
- Click OK.
- In the Corridor Properties – Rebuild task dialog box, click Rebuild the Corridor.
Note: If the task dialog box is not displayed, the corridor is still built.
The corridor model is built and looks like this:
