ShoulderMultiLayerVaryingWidth

Attachment

The attachment point is at the inside edge of the paved shoulder, which is typically at the outside edge-of-traveled way.

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 in the AutoCAD Civil 3D User’s Guide Help.

Parameter	Type	Status
Shoulder Width	Alignment that defines the edge of the paved portion of the shoulder. May be used to override the fixed Shoulder Width and tie the edge-of-shoulder to an offset alignment. The following object types can be used as targets for specifying this: alignments, polylines, feature lines, or survey figures.	Optional

Output Parameters

Parameter	Description	Type
Daylight Slope	Slope of the daylight link	Numeric
Daylight Offset	Offset of the subgrade daylight point	Numeric
Daylight Elevation	Elevation of the subgrade daylight point	Numeric
Shoulder Width	Width of the paved shoulder	Numeric
Shoulder Slope	Slope of the paved shoulder	Numeric

Behavior

The finish grade of the shoulder is inserted for the given Shoulder Width and Default Shoulder Slope outward from the attachment point. The shoulder daylight link can be inserted with either a fixed slope (Daylight Type = Slope), or a fixed width (Daylight Type = Width). If a fixed slope is used, the daylight link is extended from the outside edge of the shoulder until it intersects the bottom link (L11). Otherwise, the bottom layer is extended for the Daylight Width beyond the outside edge of the shoulder, and the daylight link is connected to the end of the bottom. All links follow the slope of top link (L1).

Layout Mode Operation

In layout mode, this subassembly displays the links comprising the shoulder for a normal crowned roadway situation. If numeric slope values are given for the Shoulder % Slope and Subbase % Slope, the links are shown at the given slope values. Otherwise the default slopes of -6% are used.
