Reading the overlay: line direction arrows show the direction of flight.
Enroute transitions draw thin, the common route thick, and runway transitions / finals medium —
select a whole STAR to watch its enroute feeds funnel into the common route and fan back out to each runway.
Altitude windows at a fix read like the chart: ≥ at-or-above, ≤ at-or-below, a range is a window, @ mandatory.
Dashed legs are heading/vector segments (drawn to an estimated length); a thin dotted grey line bridges
gaps where the coded route breaks and ATC vectors you to the next segment.
In the 3D view the ribbon height is altitude (vertical scale exaggerated; posts drop to the ground track).
