Create roads

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.

Use orthographic top view to place the plan alignment, then switch back to perspective view to inspect terrain. Arcs, transition curves, and ramps need enough length; avoid placing endpoints too close together.
