This section features the different elements the segment contains, as well as the different buttons for interacting with them. Their functions are described below. 

          The date field is filled in whenever the file that it refers to is found on the computer, showing its date.

Import: Depending on the element selected, by pressing this button MDT requests the respective file and once selected this becomes a part of the segment.  For example, if the Longitudinal option is activated by pressing this button the program will request a file with the file ending *.LON.

Automatic: Pressing this button automatically imports all the files found in the same folder as the segment and with its same name.

Select: This option is only accessible for the horizontal alignment, the longitudinal and the vertical alignment. It allows us to graphically select the element instead of importing it necessarily from a file. 

Export: Similar to the previous button, by pressing this one MDT will export the selected element to a file. This option is very useful for updating information if the segment content has been modified in a command later executed.

Delete: Deletes the information the segment of the element has associated with the element selected.

View/edit: Enables visualization of the element selected. Editing is carried out on an external editor and changes can be made on the majority of the elements, but these changes will only be kept for the segments and not the files they depend on. To update the files use the Export option mentioned previously. 

List: This enables listing the elements selected. Changes can be made to the lists, but these changes will only be maintained in the segments and not in the files they depend on.  To update the files use the option Export mentioned previously.

Recalculate: This option is another alternative to importing. For superelevations and shoulders it is only necessary to define the horizontal alignment. To make it possible to use these with longitudinal profiles and cross-sections, it is necessary to have a surface and its respective files defined. MDT analyses them to extract the interval between profiles and then recalculates them, updating the information.

Print: Use this option to extract the object selected in a selected output file (printer, pdf, excel, etc.). 

Advanced:This option has been designed for those components that require additional configuration and it can now only be used for the configuration of the additional width application point. Upon selecting the Additional widths option and pressing this button the following window will appear in which we will indicate the application vector.
