Cutting slopes are defined as the vectors that set the closure of a cross-section template with the terrain. They are applied to the last vertex formed by the ditch or subgrade, providing this vertex has an elevation lower than that of the terrain in abscissa. It is likewise applied to the last subgrade vertex when its height is lower than that of the terrain compared to the same abscissa value.

Slope: To select the slope to apply in the current station.

Side: Side of the slope application.

Application: To indicate whether the slope will be connected at the crown or foot of the roadbed.

Interpolate: If this box is checked, in the previous stations where slope is not explicitly assigned it will be interpolated.

 This button is used to insert a new assignment for the cutting slopes. At first the following window will be displayed:

 

          The slopes to be assigned are defined in this window. It is possible to assign up to a maximum of three at the same station, depending on the application point of each.

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

Assigned Slopes: The slopes are selected with the buttons “Insert”, “Edit ” and “Delete”. When “Insert” or “Edit” is pressed the following window appears for defining the slope.

 

The functions for the buttons are described below:

Number: Drop-down list for selecting a slope from the section file.

Description: For writing in text to identify the defined cutting slope. It is not a required parameter but is of enormous use in the assignment of templates as it enables easy identification of each of the assigned slopes.

Delete: Deletes the current slope and automatically goes to the next one, should one exist.

Print: Sends the slope content to the printer.

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

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

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

Import: Imports any .TAL file and adds it to the current slopes. All this information is stored in the section file selected.

This creates a Normal type slope by default and assigns it the number following the last on the list. To define different types of slope, proceed as follows.

Under Slope Type there are three possibilities for defining the type of slope to be applied:
