Hi Community

Im new to Dynamo and struggling with some list problems.

Im looking for a flattening solution for the following problem:

my XYZs output of an intersection event has a structure like this:

A

#B

##C (1 point)

##C1 (1 point)

##C2 (1 point)

...

#B1

##C0 (1 point)

##C1 (1 point)

##C2 (1 point)

…

What i actually need is a structure where all C lists are merged to one

and empty lists will be deleted (flatten from right to left):

A

#B (12 points)

#B1 (8 points)

But when I tried the flatten component in Dynamo, it gives me a structure like this (flatten from left to right):

B1

#C1

B2

#C1

B3

#C1

I hope you understand my problem and give me some hints to find a solution.

Thanks in Advance

Chris
