CXPTSExport et import (CSV)Version 1.0.0Testé dans AutoCAD

Tracer des points nommés depuis un fichier CSV

Trace des points de type levé topographique depuis un fichier de tableur : nom, X, Y et Z en option deviennent un point avec son nom écrit à côté.

Télécharger cxpts.lsp Conditions LISP

Comment l'utiliser

Préparez un CSV avec les colonnes nom, x, y et, en option, z.
Saisissez CXPTS et choisissez le fichier.
Les points et leurs noms apparaissent sur le calque courant.

Bon à savoir

Le style de point passe temporairement à une croix bien visible pendant l'exécution, puis revient à son état d'origine.

Le charger dans AutoCAD

Enregistrez le fichier où vous voulez.
Tapez APPLOAD, choisissez le fichier et cliquez sur Charger.
Tapez le nom de la commande : CXPTS.

Pour l'avoir à chaque démarrage, ajoutez-le à la Mallette de démarrage dans la même boîte de dialogue, ou chargez un dossier entier d'un coup avec le chargeur facultatif. À propos du chargeur facultatif

Testé dans AutoCAD (version complète). D'autres programmes qui exécutent AutoLISP peuvent fonctionner, mais ils n'ont pas été testés.
