Convert from Cross-Sections

          This utility is used to obtain a longitudinal profile file from cross-sections. The process transforms the cross-sections’ stations into distances, which are then assigned the height of each profile’s horizontal alignment, either directly or by interpolation. The program simply requests the cross-section file one wishes to use as a reference and the name of the longitudinal profile file which will contain the results. It then makes the conversion.
Example: Cross-sections and longitudinal profile obtained from them
