Hi @sega, if I understood your requirement correctly, this procedure could be a solution.
- Swap the Y and Z coordinates of the line (CoordinateSwapper).
- Create equi-interval horizontal lines which cover the source line. Here, the Y axis direction is equivalent to the original Z axis direction, since the Y and Z coordinates of the line have been swapped at first.
- Generate all cross points between the source line and the horizontal lines (Intersector).
- Split the source line at the cross points (PointOnLineOverlayer).
- Recombine the split line into a single line (LineCombiner).
- Swap the Y and Z coordinates of the line to restore the original axes (CoordinateSwapper).

Hello Mr. @takashi, I'd like to ask you how to extract multiple las from one by their elevation values, e.g. one would be from 2 to 4 meters, then 4-8, 8-10 and so on. A very simple tool would be great. I am working on forest point clouds, I need to access different strata, thank you in advance!
