Calcul d'une longueur de polyligne non fermé dans un tableau

le 24 août 2023

Bonjour à tous,

Je me permets d'écrire sur ce groupe pour avoir un peu d'aide sur mon problème. J'aimerais récupérer sur un tableau la longueur des polyligne non fermé que je sélectionne.

Un lips fait dejà ce travail pour l'information de l'aire. Seulement il le fait sur une polyligne fermé.

Le voici :
