Guidance to 3D Lines
Horizontal guidance to a 3D line is given by default when the 3D line is first selected for a vertical guidance. In the cross-section view guidance screen, the selected alignment is drawn with a vertical red line. If a horizontal offset is applied, the selected alignment is drawn with a double-width black tick mark, and the working alignment is drawn with a vertical red line.Illustration 6 shows a cross-section view guidance screen when a 3D line is selected for horizontal guidance and a horizontal offset has been applied.

If a horizontal offset is applied, the selected alignment is drawn with a double-width red line, and the working alignment is drawn with a double-width blue line.Illustration 7 shows a plan view guidance screen when a 3D line is selected for horizontal guidance.

The master alignment of a sloping surface can be selected as a horizontal guidance line. The master alignment is alignment number "0".In the cross-section view guidance screen, the selected alignment is drawn with a vertical red line. If a horizontal offset is applied, the selected alignment is drawn with a double-width black tick mark, and the working alignment is drawn with a vertical red line.Illustration 8 shows a cross-section view guidance screen when the master alignment is selected for horizontal guidance.

Plan view of a road design with a horizontal offset applied (1) Selected AlignmentFor sloping surfaces that are 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.Plan Lines
You can select the following design features for horizontal guidance:
Design boundaries
Site map linework
Background plan lineworkMost designs have an associated boundary that can be graphically selected for horizontal guidance. A boundary indicates the extents of the vertical design data. Any line that appears in the site map or background plan can also be selected for horizontal guidance.Note: You cannot select design text
