TMS FNC HERE Directions — Guides
Truck routing
Set TruckOptions properties to apply vehicle-specific restrictions: Height, Width, Length, Weight, and TunnelCategory. When any truck option is set, HERE plans routes that comply with the constraints.
Directions options
Use the Options property (TTMSFNCDirectionsOptions) to control avoidance zones, toll preference, and other routing parameters.
Result handling
Handle OnGetDirections to receive route data. The result structure is the same as TTMSFNCDirections — a collection of TTMSFNCDirectionsItem entries with legs and steps.
