DaylightToROW

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.

Parameter	Description	Type	Default
ROW Offset from Baseline	+/- offset of the right-of-way limit 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.	Numeric	3.0 m 10.0 ft
Offset Adjustment	+/- value added to the ROW Limit Offset. A negative adjustment value moves the daylight point inside of the ROW limit; a positive value moves it outside the ROW limit.	Numeric	0.0
Rounding Option	Specifies to round off the daylight link at the catch point	String	None
Rounding By	Specifies what parameter is used for rounding	String	Length
Rounding Parameter	Specifies value for length or radius	Numeric, positive	1.500 ft
Rounding Tesselation	Specifies number of intermittent points on rounding links (maximum 10 links)	Numeric, positive	6
Place Lined Material	Specifies to place optional material lining along daylight links. You can choose All Links, Daylight Links, Fill Links Only, and None.	String	None
Slope Limit 1	Specifies the slope limit until which the associated material lining is placed	Slope	1 : 1
Material 1 Thickness	Specifies the thickness of lined material. This thickness is measured perpendicular to the link.	Numeric, positive	12 inches
Material 1 Name	Specifies the name of the material applies for lining along grading links	String	Rip Rap
Slope Limit 2	Specifies the slope limit until which the associated material lining is placed	Slope	2 : 1
Material 2 Thickness	Specifies the thickness of lined material. This thickness is measured perpendicular to the link.	Numeric, positive	6 inches
Material 2 Name	Specifies the name of the material applies for lining along grading links	String	Rip Rap
Slope Limit 3	Specifies the slope limit until which the associated material lining is placed	Slope	4 : 1
Material 3 Thickness	Specifies the thickness of lined material. This thickness is measured perpendicular to the link.	Numeric, positive	4 inches
Material 3 Name	Specifies the name of the material applies for lining along grading links	String	Seeded Grass

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.

Parameter	Description	Status
ROW Offset	May be used to override the fixed ROW Offset and tie the ROW 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.	Optional
Daylight Surface	Name of the daylighting surface. The following object types can be used as targets for specifying the surface: surfaces.	Required

Output Parameters

Parameter	Description	Type
Daylight Offset	Offset of the daylight point	Numeric
Daylight Elevation	Elevation of the daylight point	Numeric

Behavior

The daylight offset is calculated as the ROW Limit Offset plus or minus the Offset Adjustment. A daylight link is inserted from the attachment point to the calculated offset on the target surface.

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.

Note:

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 right-of-way offset, plus or minus the offset adjustment. The daylight link terminates with an arrowhead pointing outwards.

Point, Link, and Shape Codes
