How to group list beam?

Hello all brothers!
To day, I would like to filter the beam in one line and group them in the list. How cant i do it? Please!!! Thank you so much!

i dont know what is your required direction, but i will assume that you need all line in X direction,
the idea is that all line in x direction have the same (start end point )value in Y direction.

so, get Y value @ start point
get Y value @ end point
compare these 2 lists which is equal

now you have a list with True, Flase values , you can filter your beam list according to it using FilterByBoolMask
