Lane Marking

The Lane marking tool is used to define and customise lane markings along the selected road lane. You can apply different marking styles, colours, widths, and patterns on the same lane according to road design requirements.

On the canvas, lane markings are driven by anchors placed along the selected lane. Each anchor marks where a lane marking configuration starts or changes.

Lane Marking Anchors

Lane marking anchors sit on the lane and define lane marking regions and transitions.

  • Several anchors can exist on the same lane.
  • Different styles can apply between anchors (segment by segment).
  • Anchors give precise control over how markings change along the road.
  • You can select an anchor and drag it along the road to move its position.

You can turn on lane marking in either of the following ways.

1. From the Lane Property Panel

  1. Open the Lane property panel (with the target lane selected).
  2. Go to the Advanced tool section.
  3. Enable the Road Marking toggle.
  4. Add an anchor at the desired position on the lane.

2. From the Road Toolbar

  1. Triple-click the target lane on the canvas so lane selection is active (see selection on the canvas).

Enable the Define line toggle to build custom lane marking patterns—for example dashed or segmented lines.

Scope and Quality

  • Markings cover longitudinal lines along lanes (solid, dashed, double, custom dash via Define line) and fit lane sections and junction context.
  • Prefer markings that match local highway rules for your scenario; misalignment with lane width or topology can show up in review and in simulators.
