TMS FNC Route Calculator — Guides
Route building
Users build routes by clicking waypoints on the map. The route calculator draws polyline segments between points and fires OnCalculateRoute when the route is updated.
Undo and redo
Call Undo and Redo to step through the route edit history. The HistoryManager property exposes the full undo/redo stack.
GPX import and export
Export the current route to a GPX file by calling SaveToGPX. Load a previously saved route by calling LoadFromGPX.
Route options
Configure polyline appearance, routing mode (driving, walking, cycling), and directions integration via the Options property (TTMSFNCRouteCalculatorOptions).
