How do I use filterbyboolmask to filter a list when inputs lists have different levels

Hi, I’m trying to get the points inside of bounding box,
There are 4 bounding boxes and 6 points, 4 points are in the boxes,I could see that from the result of BoundingBox.Contains node and tried to get points which have true value = inside of the boxes…
I’ve changed the lacing of the List.FilterByBoolMask node and inputs levels but couldn’t get the correct result. Do I need to change the node or change levels of inputs?

When I’m in this situation, I query if any of the results are true in the sub list because there will only be one true if any of those 5 items exist in that bounding box. We can use List.AnyTrue and have it look at each bool in the sub list via list @ level.

Hopefully this helps!

Change the list level of the mask input to be @L2. This will make it so that each sublist (representing the points in a particular bounding box) is filtering the list of points. Each sublist represents the bounding box and the filtered list will represent the points it contains.


Hi, @jaeho
Maybe simple python script can hepl you.

import sys
import clr
from Autodesk.DesignScript.Geometry import *

lns = IN[0]
pts = IN[1]

intersect = []
for pt in pts:
	sublst = []
	for ln in lns:
		if Geometry.DoesIntersect(pt, ln):

OUT = intersect
