LinkSlopeToSurface

This subassembly is a general purpose utility to extend a link from the attachment point at a given slope to the closest intersection with a target surface.

Attachment

The attachment point is at the beginning of the link.

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.

Parameter	Description	Type	Default
Side	Specifies which side to place the subassembly	Left/Right	Right
Use Superelevation Slope	Specifies to use superelevation slope	Selection list	No
Slope Direction	Specifies whether the link slopes away from the crown or towards the crown	Selection list	Away from Crown
Slope	% slope of the link	Numeric	2 (%), (or 2:1)
Add Link In	Specifies to add link in cut, fill, or cut and fill conditions	Selection List: a) Cut and Fill, b) Cut Only, c) Fill Only	Cut and Fill
Point Codes	A list of surface codes to be assigned to the outside edge of the link	Comma-separated string	P2
Link Codes	A list of codes to be assigned to the link	Comma-separated string	Top, Datum
Omit Link	This parameter adds or removes the surface link	Yes/No	No

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.

Parameter	Description	Status
Target Surface	Name of the surface the link is tying to. The following object types can be used as targets for specifying this surface: surfaces.	Required

Output Parameters

Parameter	Description	Type
Begin Offset	+/- offset of the beginning of the link	Numeric
Begin Elevation	Elevation of the beginning of the link	Numeric
End Offset	+/- offset of the end of the link	Numeric
End Elevation	Elevation of the end of the link	Numeric

Behavior

A link is extended to the left or right from the attachment point at the given slope until it intersects the target surface.

By default, a cut or fill link will be added from the attachment point to the target surface. If the link needs to be added only in cut or fill conditions, specify appropriately a value for the Add Link In property of the subassembly. If the cut link and fill links must be at different slopes, then add this subassembly twice, at the same attachment point, once for Cut Only and then again for Fill Only conditions, with slopes as needed.

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 Slope, d)Inside Lane Slope, or e) None. None is the default setting.

Layout Mode Operation

In layout mode, this subassembly attempts to find the intersection of the link, if the target surface was inserted by a previous subassembly. If an intersection is found, the link is displayed at the given slope to the surface. If not, the link is displayed at the given slope outward for a slope distance of 3 meters or 10 feet, terminating in an arrowhead pointing outward.

Point, Link, and Shape Codes

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.

Point, Link, or Shape	Code	Description
L1	Daylight_Cut	If the link is added in cut condition.
L1	Daylight_Fill	If the link is added in fill condition.

Note:

You can add other codes for points and links as needed using the input parameters listed for this subassembly.
