Rhino 8.7, Windows
Exported geometry: 01.3dm (57.5 KB)
Steps to reproduce:
- select all
- join
- observe some curve segments get deleted!
Animation of what happens:
I found this thread: I have experienced this behaviour too and I think I understand how it happens - Rhino basically folds the polycurve over itself. It seems my file is a whole different thing: yes, there are duplicate curve segments but
- it is not the duplicate segments but different ones that disappear (in one case they border the duplicates, in another they are not even connected)
- these segments are straight away deleted!

(Is this some sort of borked list manipulation?)
