I'm working with a multiple list that contains 31 individual lists. My goal is to deduplicate each of these 31 lists and then compile the results into a new multiple list. I have a couple of questions regarding this process: 1. Does the `deduplicate()` function process the lists within a multiple list individually? 2. Is it possible to write a modified list back into an existing multiple list? 3. Could you provide guidance on how to create a new multiple list and append the deduplicated results of each of the 31 original lists to it? Thanks for your help!

1. No, deduplicate operates on a single list. 2. It is never possible to "write something back" somewhere. You always have to rewrite a new version with the desired changes. 3. I think you want something like this: newlist = [for(sublist=list) deduplicate(sublist)] On Sat, May 24, 2025 at 10:04 PM Joe Weinpert via Discuss < discuss@lists.openscad.org> wrote: > I'm working with a multiple list that contains 31 individual lists.

Yes Adrian ... that worked, thanks!
