Recréer le contour d\'une zone hachurée

[alainterieur]

Bonjour à tous,

J'ai récupéré un fichier dwg que je dois importer dans un SIG.

Problème, les zones que je dois importer sont représentées par des hachures sans contours, donc je ne peux pas les importer.

Y'a-t-il un moyen dans AutoCad Map 2000i de recréer les contours des zones plutôt que de devoir tout refaire à la main ?

Merci de vos réponses.

Re,

J'ai bien récupéré ton lisp, je l'ai bien chargé dans AutoCad apparemment, mais comment on l'utilise ?

AutoCad n'est pas mon logiciel de prédilection, je l'utilise de manière ponctuelle et ne connait que quelques fonctions de base.

Merci.

bonjour,

Une fois le lisp chargé, tu tapes HB sur la ligne de commande et il te reste plus qu'a suivre les instructions.

@plus

PS pour charger une application tapes appload sur la ligne de ommande.

[alainterieur]

Merci à tous,

Ca marche nickel et ça va me faire gagner un temps monstre !!

Cordialement,

..qq'un a fait un topo étape par étape sur le chargement des lisp mais je ne retrouve plus... :casstet:

Je l'ai retrouvé là
