I tried this but not working , can you please help

I made a script for this a while ago. Have a look at it, it might help you.
Corridor_Merge.dyn (130.1 KB)

similar I use a Corridor_Duplicate to create a copy wich I ca split and cleanup later.
Corridor_Duplicate.dyn (51.8 KB)

I think it is based on C3D 2022 so maybe there are a few bugs to fix before it works.
