Just had a look at these - The top one is the one type of tree structure I didn’t try!
Unfortunately, I need these as separate pieces. The example I uploaded was a simplified problem. In reality, these extrusions are going to stop before hitting the next profile.
I looked into splitting the continuous one (sweep issue_re2) through creating a planar surface, hpwever I cannot seem to split these curves all at once (I end up getting several sets of two). Sorry to be a pain - but you don’t happen to know how to “split with multiple curves” do you?
I think you are pretty much doing it from an reverse engineering approach,
worth thinking about how did you align those section profiles in the first place.
Also from my exp, make sure you have consistent seam for section profile and rails,
especially when you have rails that might be closed curves.
It usually works better when having rails running through centres of the profiles.
