I wrote a script wishing to get points from a point cloud in a desired area, to do this i used the MultiPlaneFilter to box in my desired area. I am not getting points at all and when changing the direction of the normal for planes i am getting points which are not in the desired area.
This script I wrote, I also attached the file. (Warning its not pretty as its just a proof of concept at the moment):
