This text box displays a series of options to be considered depending on the cross-sections to be obtained.
Unique Points: When this option is selected, in addition to the previously determined constant interval distances, the program considers the initial and final stations and all the vertices found on the horizontal alignment, including changes of orientation, vertices when forming straight lines, tangents, etc.
Distance: This option allows one to include the cross-sections corresponding to specific stations. Activating this option enables the Distances button. A new window called Distances in Profiles is then displayed.
As can be seen, the window contains a series of buttons allowing one to edit the list of stations to be included.
Select: Allows one to graphically select the station. In order to do so, a point on screen is specified. The point thus chosen will be projected on the horizontal alignment and its distance with regard to the alignment’s initial station will be found. If there is no projection, it will not be added to the list.
Change: This command changes the station selected from the list for the one indicated in the Distances text box.
Delete: Deletes the station selected from the list.
Load and Save: These commands load or generate a .DST file respectively, or a distance in profiles file where which each line indicates a station.
Clear: Deletes the entire list from the window.
Points: Provides access to the Point Selection window to determine the set of points whose stations one intends to project onto the horizontal alignment. (see Point Selection in the Points section).
Interval: This option allows one to extract cross-sections having the interval entered using this control.
Distance on Curves: The on-curve interval value with which one wishes to obtain the profiles is entered in this field
First station: This value indicates the horizontal alignment’s first station from which the profiles will be obtained.
