Reference features are terrain features (points, poly-lines etc) or other alignments. They can be displayed (projected or intersected) in the Profile, Plan and Section windows or used for template control.
Reference feature sets are associated with a specific horizontal alignment.
The list box at the top of the dialog box contains a set of predefined reference feature placeholders e.g. Reference Feature 1, Reference Feature 2...
