Thank you for trying to help.
But I couldn't find "use skin end lines" in Composite Structures,
and "Apply structures settings" in Wall Settings.
If you look at the pictures of the 2 wall ends, one shows a faint wall end (when I activate show "both" ends in Wall Settings, and the other shows nothing when I deactivate wall ends.
Thanks again .
