I’m trying to repeat the same process on each group of features that represent each door (every door consists of many features having the same value of door_id) .
on the other hand , the process that i want to create is detecting that line on green for each door and drawing it using the LineBuilder .
So for exemple ,
if in my input i have : 200 features , every 30 or 40 features share the same door_id value (so there are say 6 doors in total )
my output : 6 features (each feature is that green line , with the attribute door_id)
