Hi Laurent,
Thx for sharing this script - great help!
I tested it on Rhino 6 & 7 - unfortunately, there seams to be a problem using it on Rhino 7 (looks like there is a problem with selecting the right trimmed sides (for both the multi and non multicurve version I found here).
edit: might be that it worked yesterday - did an Rhino 7 update today.
