Fill slopes are defined as the closure of a cross-section template with the terrain. These are applied to the last vertex making up the ditch or the subgrade, as long as that vertex has a greater height than the terrain in abscissa. They are also applied to the last subgrade vertex when its height is greater than that of the terrain compared with the same abscissa value.

Slope: Selection of the slope to apply in the current station.

Side: Side of the slope application.

Application: Indicate whether the slope will connect at the crown or foot or the roadbed.

Interpolate: If this box is checked in the previous stations that are not explicitly assigned the slope will be interpolated. 

 This button is used to insert a new fill slope assignment. Initially the following window will be displayed:

          This window is used to define the slopes to be assigned; it is possible to assign up to a maximum of three at the same station, depending on the point of application of each.

Apply: Specify up to which station the slope or slopes selected are to be applied.

Assigned Slopes: The buttons “Insert”, “Edit” and “Delete” are used to define slopes. When any of them is clicked the following window will be displayed for defining the slope.

A description of the functions of each button follows:

Definition of Routings Drop-down list for selecting a slope from those existing in the section file. 

Description: Text for identifying the defined fill slope. It is not a necessary parameter but it will be of enormous use in the assignment of sections as it makes each slope assigned be easily identified.

Delete: Deletes the current slope and automatically moves to the next slope if one exists. 

Print: Sends the slope content to the printer.

Copy: Creates a slope identical to the current one and assigns it the next number following the last on the list.

Export: Displays a window containing all the slopes ready to be exported, so that any of them may be selected. 

          Once validated, the slopes marked are exported to the file that is then requested. The output file is an ASCII file and has a .TAL extension.

Import: Imports any file with a .TAL extension and adds it to the current platforms. All this information is saved in the section file selected.

New: Creates, by default, a Normal-type slope, assigning it the number following the last on the list. To identify different types of slopes proceed as follows.

Select the Slope Type to define one of the three options for slopes that can be applied.
