Codes can be associated with the point, link, and shape components of a subassembly.
Codes allow you to apply simple or complex rules governing the offset and elevation behavior of subassemblies. You can choose to add codes to certain subassembly components to implement presentation or annotation features to a corridor design.
A typical subassembly is comprised of the following components, which can have codes associated with them:
- Point. Define the basic subassembly structure.
- Link. Connect points to form planar structural surfaces of a corridor.
- Shape. Defined from links and define a closed region that represents materials used in a corridor model.
For a set of point, link or shape components, you can define a set of display characteristics and assign them to a code set style. You can then assign a code set style to a subassembly, assembly, corridor, or section view.
You can assign appropriate label styles to various code sets in the code set styles.

- Pavement Structure of Paved Sections
The AutoCAD Civil 3D Corridor Modeling subassemblies that model paved components of a roadway, such as travel lanes and shoulders, allow multiple material layers to be defined.
- Understanding Point, Link, and Shape Codes
The optional codes associated with a subassembly point, link, or shape components determine some of the behavior you will see in corridor modeling.
- Standard Point Codes
A set of standard codes define the display and behavior of the point components used in the AutoCAD Civil 3D Corridor Modeling subassemblies.
- Standard Link Codes
A set of standard codes define the display and behavior of the link components used in the AutoCAD Civil 3D Corridor Modeling subassemblies.
- Standard Shape Codes
A set of standard codes define the display and behavior of the shape components used in the AutoCAD Civil 3D Corridor Modeling subassemblies.
- Adding Codes to a Subassembly
Add codes to a subassembly created from a polyline.
- Using Code Set Styles
Use code set styles to control the visual appearance of a code set (link, point, and shape codes). You can create specific styles to use for the different aspects of an assembly or corridor.
- Localizing or Modifying Subassembly Codes
For localization purposes, the AutoCAD Civil 3D stock subassemblies use an external codes file to define the point, link, and shape codes referenced in the subassemblies.
