This page is the landing page for road creation. Most tools follow the same rhythm: choose an action, click points in the scene, read the preview, then confirm generation. If in-game labels differ from this page, follow the current in-game UI.
Straight and arc elements are the basic building blocks of road creation. Straight elements are best for simple links, while arcs are used for turns and radius-controlled curves.
When alignment editing is active, roads show draggable control points. Depending on the element, you may see start, end, radius, or ramp-port points.
Extend tools continue from the end of an existing road. Transition-curve connection joins two roads more smoothly, avoiding abrupt direction or curvature changes.
Road tools communicate through temporary roads, preview lines, highlights, and failure text. If no preview appears, the cursor may not be hitting terrain or a road, a required road may not be selected, or a toolbar may be taking input.
