In a project, once an alignment is established, it can be viewed in the Project Explorer and identified in plan view. To modify the alignment, users can access the Alignment Editor. If multiple alignments exist, one can be selected by right-clicking and choosing 'edit' to open the Alignment Editor. Alternatively, the Alignment Editor can be accessed via the corridors tab. Within the editor, users can adjust vertical or horizontal values, which are highlighted in blue, indicating they are changeable. Additionally, station equations and super elevation values can be added to meet specific design or project requirements.
