3D lane shape
ο»Ώ
This geometry shape is drawn using the 3D lane tool. It is mainly used to mark road markings. What differentiate it from 3D linesο»Ώ is that you can adjust the line's width, in other words set the left and right boundaries.
We recommend using the Point slicingο»Ώ in tasks where vehicles on the road may obscure the points of interest on the ground.
Set width
- Select a class,
- Click at either the leftmost or rightmost edge of the line,
- A red indication should appear
- Click at the opposite edge
- This should create a lane marking shape

Place points
- Move along the lane markings and place points where you want to have control points.
- The points will be placed at the lowest point in the point cloud at that location.
- Continue placing points until you feel done with the object.

- Use the 3D Transformation controlsο»Ώ to adjust the placement of the line point. To adjust the entire line you need to press shift before moving the controls.
- Zoom to selected to quickly review the points along a line using k
- Step between points using alt nand alt p
