Hi Pilou,
many thanks for your reply. I'm not sure, but I think that I do the similar thing. When I prepare geometry to Flow - "Unfold" process I highlight edges of part profile first, then I use Offset command to take Base curve which goes in the middle of material thickness. Offset curve is Joined automatically. This curve I Unwrap as a target curve. After that I highlight part (solid), point the Base Curve, then Target curve and then I obtain planar solid. If I color faces before Flow, so result is planar solid with coloured faces. Each unfolded face correspond to original.
I've tried to use your script but I'm not sure if I use it correctly. I choose some curve run the script by shortcut and in clipboard is saved length of selected curve.
May I ask you for explanation in more details, please.
Thanks a lot.
Mik
