This subassembly is a general purpose subassembly to add a series of connected links.
This is typically used to add structural shapes that are not pre-defined as subassemblies. Up to 12 links may be specified. If a shape requires more than 12 links, the LinkMulti subassembly can be used multiple times.
Attachment
The attachment point is at the beginning of the first link. The subassembly is sensitive to the direction being inserted. Positive widths increase the offset from the attachment point in the direction inserted.
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.
Target Parameters: None.
Output Parameters
None.
Behavior
Up to 12 links are inserted in sequence at the given widths and vertical deflections. Shapes are not automatically closed; a closing link must be included.
Layout Mode Operation
In layout mode, this subassembly displays the links defined by the input parameters.
Point, Link, and Shape Codes
Point and link codes are as specified in the Input Parameters list.
Coding Diagram
Points are numbered sequentially from the beginning of the first link from 1 up to 13. Links are numbered sequentially from 1 up to 12.
