Design Boundary Line
Most designs have an associated boundary. The boundaries indicate the extents of the data for the vertical design. A boundary can be graphically selected for horizontal guidance. Refer to Operation and Maintenance Manual, "Horizontal Guidance Alignment" for more information.Site Map and Background Plan Linework
Any line that appears in the site map or the background plan can be graphically selected for horizontal guidance.Note: You cannot select text items and avoidance zone boundaries for horizontal guidance.Road Alignments
Each alignment in a road design file (*.dc) is numbered, and can also be given a name. The master alignment is always alignment number 0. Positive alignment numbers are alignments to the true right of the master alignment. Negative alignment numbers are alignments to the true left of the master alignment.Note: True right and true left mean right and left in the direction of the road when you are looking away from the starting point or the first station in the design. If the machine is facing back toward the start of the road, the positive alignments appear to the left of the master alignment.If the selected alignment stops at the current station, horizontal guidance is no longer given. However, the system remembers the alignment. Horizontal guidance resumes when the selected alignment reappears.Sloping Surface Alignment
The master alignment of a sloping surface can be selected as a horizontal guidance line. The master alignment is alignment number 0.For sloping surfaces defined by the 2 points method, the direction of the master alignment is from the first point toward the second master alignment point.For sloping surfaces that are defined by the point-and-direction method, the direction of the master alignment is the direction specified. Refer to Operation and Maintenance Manual, "Sloping Surface Design" for more information about these methods.
