Working with the Design Data (Stringlines and Layers)

Depending on the complexity of the road job, the design data may vary from being a single
horizontal alignment to a design containing profiles with dozens of defined vertices. Road-
Runner offers the possibility of grouping these design elements logical for faster access.
When manually typing in a road job, alignments and cross sections are used. Alignments are
defined by geometric elements, for example straights and arcs, and the cross sections by
vertices. Furthermore, one defines at which chainage a certain cross section is used. By
doing this the vertices are connected to create a series of lines representing the three dimen-
sional design of the road.

In RoadRunner such lines defining the design are called stringlines. Stringlines are the base
elements used for stake out and check activities. Stringlines have a project unique name by
which they are identified and selected. Whenever a new road design is typed in or imported
from a design package these stringlines are generated automatically in the background.
