You first encountered the C1VectorPolyline class in the Vector Objects topic. In that topic, you created a polyline that connected three points on the map. With the C1VectorPolyline, you can create a more complex route map, for example, following the route of the Trans-Siberian railroad.

In this tutorial, you'll create a project that will show the route of the Trans-Siberian railroad by marking the main cities or stops on the route.
