These topics describe the construction and behavior for each subassembly included in the AutoCAD® AutoCAD Civil 3D® Corridor Modeling catalogs. For more information on subassemblies, see Assemblies and Subassemblies in the AutoCAD Civil 3D Help.
The subassemblies in this subassembly reference are organized alphabetically into the following sections:
AutoCAD Civil 3D subassemblies are preconfigured AutoCAD drawing objects that let you design three-dimensional sections of roadways and other corridor-type structures.
Review this topic to determine which subassemblies you may want to use in your designs when building corridor assemblies.

This subassembly creates a a simple curb at the edge of roadway. It can be attached to either outside edge of pavement or to the edge of a median on the inside.
This subassembly creates a a simple curb and gutter structure at the inside or outside edges of roadway.
This subassembly creates a simple guardrail shape on the assembly.

This subassembly automatically applies various subassemblies, such as generic links, widening, ditching, or daylighting subassemblies, to an assembly based on whether a cut or fill condition exists.
This subassembly automatically applies various subassemblies, such as widening, curb and gutter, ditching, or daylighting, to an assembly based on whether an offset target is found at the corridor station.
This subassembly creates a crowned lane that has separate subbase slope control, as well as the ability to control the subbase crown location by specifying a target alignment.
This subassembly inserts links to create a basin and cut daylight slope for a cut condition, or a basin, berm, and fill slope for a fill condition.
This subassembly is similar to the DaylightBasin subassembly with the following additional behaviors:
This subassembly inserts links to create cut or fill catch slopes with repeating benches as needed.
This subassembly is a generalized solution to closing the sections from the outside edge of roadway to cut or fill intercept point.
This subassembly inserts a daylight solution that will use a typical slope as long as the daylight is within the ROW limits.
This subassembly inserts a link that extends to a target surface at a user-defined cut or fill slope.
This subassembly inserts a link that daylights to a target surface at a user-defined cut or fill slope.
This subassembly inserts a link that daylights to a target surface at a user-defined cut or fill slope.
This subassembly inserts a link that daylights to a target surface at a user-defined cut or fill slope.
This subassembly is used when a cut or fill daylight slope may have more than one intersection with the target surface.
This subassembly lets you specify three surface layers and cut slopes for each material type.
This subassembly lets you select both an existing ground surface and a rock surface as targets.
This subassembly creates corridor-side daylighting links with user-defined slope configurations, such as flat, medium, and maximum slopes for cut and fill situations.
This subassembly inserts a daylight link from the attachment point to a given offset from the baseline.
This subassembly inserts a daylight link from the attachment point to a given offset from the right-of-way limit on a target surface.
This subassembly inserts a flat or V-shaped ditch with user-defined horizontal and vertical control parameters.
This subassembly creates a simple pavement structure with user-definable point, link, and shape codes.
This subassembly creates a cross-sectional representation of travel lanes for a broken-back roadway, where the inside and outside lanes have different downward slopes.
This subassembly inserts one or more travel lanes outward at a constant grade from an alignment that defines the edge of a median that tapers to allow for left-turn lanes.
This subassembly inserts one or more travel lanes outward from an alignment that defines the edge of a median.
This subassembly creates a cross-sectional representation of finish grade, base layer, and subbase layer for a travel lane, applying the Inside Lane superelevation slope value for the corridor model’s baseline alignment.
This subassembly creates a cross-sectional representation of a lane comprised of multiple layers. The layers can be of varying widths. It also applies the Outside Lane superelevation slope value for the corridor model's baseline alignment.
This subassembly is similar to the LaneInsideSuper subassembly. However, there are additional layers within this subassembly, and the bottom layer does not follow the same slope as the finished grade. Instead it is controlled by an inside height and outside height.
This subassembly creates a cross-sectional representation of a travel lane, applying the Outside Lane superelevation slope value for the corridor model’s baseline alignment.
This subassembly creates a cross-sectional representation of a lane comprised of multiple layers. The layers can be of varying widths. It also applies the Inside Lane superelevation slope value for the corridor model's baseline alignment.
This subassembly is similar to the LaneOutsideSuper subassembly. However, there are additional layers within this subassembly, and the bottom layer does not follow the same slope as the finished grade. Instead it is controlled by an inside height and outside height.
This subassembly inserts a travel lane, applying the Outside Lane superelevation slope value, and widens the pavement at superelevated regions.
This subassembly creates a cross-sectional representation of finish grade, pavement, and subbase for urban, parabolic lanes between the left and right edges of traveled way.
This subassembly creates a cross-sectional representation of a travel lane, applying the Outside or Inside Lane superelevation slope value for the corridor model’s baseline alignment.
This subassembly creates a cross-sectional representation of a travel lane that is being inserted from the inside edge of pavement towards the crown point.
