LinkSlopeAndVerticalDeflection

This subassembly is a general purpose utility to extend a link at a slope for a vertical deflection distance.

A profile can be given for the vertical deflection when building a corridor model.

Attachment

The attachment point is at the inside edge of the link. This subassembly can be inserted in the left or right direction from the attachment point.

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 To Specify Corridor Targets.

Parameter

Description

 

Vertical Deflection

May be used to override the fixed Vertical Deflection and tie the end-of-link to a profile. The following object types can be used as targets for specifying this: profiles, 3D polylines, feature lines, or survey figures.

Optional

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 added from the attachment point in the direction of insertion for the given slope until it reaches the given elevation. If a profile name is specified at runtime, the vertical deflection is adjusted to match the profile elevation.

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

Layout Mode Operation

In layout mode, this subassembly displays the link at the given slope and vertical deflection.

Point, Link, and Shape Codes

None.
