LinkWidthAndVerticalDeflection

Last updated: 2021-02-12

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

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

A link is added from the attachment point in the direction of insertion for the given width and vertical deflection. If a surface name is specified at runtime, the vertical deflection is adjusted to match the surface elevation. If the targeted surface is not found at a given station, a warning message will appear in the event viewer and the subassembly will revert to the vertical deflection input parameter. If an offset horizontal alignment name is assigned to the Width during corridor modeling, the width of the link will vary to match the offset of the alignment. If the width target is not found at a given station, the subassembly will revert to the width input parameter.

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.

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

Info: All dimensions are in 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.

Omit Link This parameter adds or removes the surface link. Yes\No No

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.

Parameter Description Status
Vertical Deflection May be used to override the fixed Vertical Deflection and tie the end-of-link to a surface. Optional
Width May be used to override the fixed link Width and tie the end-of-link to an offset alignment. The following object types can be used as targets for specifying this offset: alignments, polylines, feature lines, or survey figures. Optional

Parameter Description Type
Begin Offset +/- offset of the beginning of the link Numeric
Begin Elevation Slope of the link from the subgrade shoulder point to the projection of the subgrade improvement layer. Numeric
End Offset +/- offset of the end of the link Numeric
End Elevation Elevation of the end of the link Numeric
Link Slope Slope of the link (negative if the slope travels downward from the baseline outwards) Numeric

None
