This command enables a horizontal alignment to be created from a group of road design elements. There are two operating modes:
Designating an element that forms part of an alignment, the program automatically includes the rest of the group elements, establishes the origin of the horizontal alignment at the appropriate extreme and proposes by default as a Station the origin of the horizontal alignment of the first element of the group.
When an element forming part of an alignment is selected, the program automatically includes the group’s remaining road design elements, sets the horizontal alignment’s origin at the correct end and proposes the horizontal alignment’s station of origin and the group’s first element by default.
When various elements are selected irrespective of how they are grouped, the program will only create a horizontal alignment with the elements selected. In addition, it is necessary to choose the end where the origin of the horizontal alignment is to be situated. Should the different elements not be at a tangent to each other, the dialog box below appears, where the station, the theoretical and real azimuths, and the difference between both are entered. By clicking on a specific line and clicking on the Draw button, the location of errors on the drawing will be represented.
