This subassembly inserts a daylight link from the attachment point to a given offset from the baseline.
You can also specify optional lined materials for daylight and other links (All Links, Daylight Links, Fill Links Only, and None).
Attachment
The attachment point is at the inside edge of the daylight link.
Input Parameters
Note: All dimensions are in meters or feet unless otherwise noted.

Daylight Offset from Baseline |
+/- offset of the daylight point from the baseline. 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. |

Target Parameters
This section lists the parameters in this subassembly that can be mapped to one or more target objects. For more information, see To Specify Corridor Targets.

Daylight Offset |
May be used to override the fixed Daylight Offset and tie the daylight offset to an offset alignment. The following object types can be used as targets for specifying the offset: alignments, polylines, feature lines, or survey figures. |

Behavior
A daylight ink is inserted from the attachment point to the surface at the given offset.
Like other daylight subassemblies, this subassembly optionally lets you add a lined material. You can specify three ranges of slopes. Material type 1 is applied if the slope of the links is up to the specified slope value. From slope 1 to slope 2, the second type of material applied. Similarly, if the slopes of links fall within slope 2 and slope 3 values, then material 3 is applied. If the link slopes are flatter than slope limit 3, then no material is applied.
If a lined material is added to the subassembly, then parallel links are added to the daylight links with specified thickness. This thickness parameter (for example, Material 1 Thickness) is measured perpendicular to the link. Bottom level links are coded with Datum and daylight links are coded with Top. Shapes enclosed by these materials are coded with material name.
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
In layout mode, this subassembly displays a link extending outwards at a -4 : 1 slope to the specified offset. The daylight link terminates with an arrowhead pointing outwards.
