Edit road alignment and vertical profile
When alignment editing is active, roads show draggable control points. Depending on the element, you may see start, end, radius, or ramp-port points.
| Control point | Purpose |
|---|---|
| Start | Adjust the start of the current element |
| End | Adjust the end of the current element |
| Radius | Adjust arc radius or curve shape |
| Ramp port | Adjust ramp port position or direction |
Drag a control point to adjust it, then release the mouse to submit. If the road is not editable, the control point will not apply changes.
Vertical profile editing adjusts elevation, grades, and grade control points. Move the cursor over a road or terrain to find station references and valid insertion positions.
