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.
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.
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.
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.
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.
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.
