This subassembly lets you specify three surface layers and cut slopes for each material type.
When transitioning between types, a bench can also be inserted.
Attachment
The attachment point is at the inside edge of the initial cut or fill slope. This component can be attached to either the left or right side.
Input Parameters
Note: All dimensions are in meters or feet unless otherwise noted. All slopes are in run-over-rise form (for example, 4 : 1) unless indicated as a percent slope with a “%” sign.

Target Parameters
This section lists the parameters in this subassembly that can be mapped to one or more target objects, such as a surface, alignment, or profile object in a drawing. For more information, see To Specify Corridor Targets.
| Parameter | Description | Status |
|---|---|---|
| Surface1 | Top Existing Ground Surface. The following object types can be used as targets for specifying this surface: surfaces. | Required |
| Surface2 | First subsurface. The following object types can be used as targets for specifying this surface: surfaces. | Optional |
| Surface3 | Second subsurface. The following object types can be used as targets for specifying this surface: surfaces. | Optional |
Output Parameters
| Parameter | Description | Type | Default |
|---|---|---|---|
| Daylight Offset | Offset of the daylight point | Numeric | Daylight Offset |
| Daylight Elevation | Elevation of the daylight point | Numeric | Daylight Elevation |
Behavior
In a fill situation, a daylight link is inserted with a slope based on the fill slope input parameter to surface 1. In cut, the subassembly first checks to determine if it is below surface 3 by applying the surface 3 slope, and checking for intersection. This process repeats for each additional surface. Optionally, between the surfaces optional transitions can be added at the surface changes. The bench width and slope for the surface that was just intersected will be used.
In Autodesk Civil 3D 2010 and previous versions, the Material Thickness parameter was measured vertically. In Autodesk Civil 3D 2011 and later, this parameter is measured perpendicular to the link. Therefore, if you open a drawing containing these subassemblies that was created in Autodesk Civil 3D 2010 or prior in Autodesk Civil 3D 2011 or later, and then rebuild the corridor(s), this parameter will be changed to reflect the new behavior. Any volume reports that use this subassembly will be updated to reflect the new behavior.
Layout Mode Operation
This subassembly displays in layout mode using the input parameters for Surface 1 Slope and Fill Slope.
Point, Link, and Shape Codes
The following table lists the point, link, and shape codes for this subassembly that have codes assigned to them. Point, link, or shape codes for this subassembly that do not have codes assigned are not included in this table.
