This subassembly is used when a cut or fill daylight slope may have more than one intersection with the target surface.
An input parameter controls which intercept is used.
You can also specify optional lined materials for daylight and other links (All Links, Daylight Links, Fill Links Only, and None).
The attachment point is at the hinge point of the daylight link. This component can be attached to either the left or right side.
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.
This section lists the parameters in this subassembly that can be mapped to one or more target objects. For more information, see in the AutoCAD Civil 3D User’s Guide Help.
This subassembly attempts to find all possible daylight points for the cut slope condition. If one or more daylight points are found, they are ordered and numbered by increasing offset from the hinge point. The daylight link is terminated at the point that matches the Intercept Number value. If the intercept number is higher than the number of intercepts found, the last intercept is used.
If no daylight points are found for the cut condition, the process is repeated for the fill condition.
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 AutoCAD Civil 3D 2010 and previous versions, the Material Thickness parameter was measured vertically. In AutoCAD 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 AutoCAD Civil 3D 2010 or prior in AutoCAD 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.
In layout mode, this subassembly displays both the cut and fill solutions in dashed lines extended outward for a distance of 3 meters or 10 feet. The daylight links terminate in arrowheads pointing outwards.
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.
