This subassembly is a general purpose utility to connect a link from the attachment point to a specified offset at a given slope.
An alignment can be substituted for the offset, and a profile for the slope.
Attachment
The attachment point is at the beginning of the link. The direction of the link is determined by the location of the given offset and slope.
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.

Offset from Baseline |
+/- offset of the end of the link. Specifying a positive value for the this parameter inserts this subassembly on the right side of a corridor, or controlling baseline. A negative value inserts it on the left side. For more information, see "Inserting Subassemblies on Right and Left Sides of a Corridor" in the Corridors chapter of the Autodesk Civil 3D User's Guide Help. |

Selection list | No |
| Slope Direction |
Specifies whether the link slopes away from the crown or towards the crown |

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.

|
Offset |
May be used to override the fixed Offset and tie the end-of-link to an offset alignment. The following object types can be used as targets for specifying this offset: alignments, polylines, feature lines, or survey figures. |
Optional |
|
Slope |
May be used to override the fixed Slope and tie the end-of-link to a profile. The following object types can be used as targets for specifying this elevation: profiles, 3D polylines, feature lines, or survey figures. |

Behavior
A link is added from the attachment point to the given offset at the given slope.
This subassembly includes an optional input parameter named Use Superelevation Slope that lets you specify to use the superelevation slope for the shoulder. This parameter can be set to a) Outside shoulder slope, b) Inside shoulder slope, c)Outside Lane, d)Inside Lane, or e) None. None is the default setting.
If the input offset value is a negative number and superelevation slope is specified (Use Superelevation Slope parameter not set to None), the values from the left side lane or shoulder will be used. If a positive offset is specified, the values from the right side superelevation will be used.
Layout Mode Operation
In layout mode, this subassembly displays the link calculated from the given offset and slope parameters.
Point, Link, and Shape Codes
None.
