Macro Airfoil Import & Scale/fr

Utilisation - Version 1.5

Sélectionner le fichier

L'exécution de la macro présente d'abord à l'utilisateur un navigateur de fichiers qui lui permet de sélectionner le fichier .dat du profil aérodynamique souhaité. Naviguez jusqu'à l'endroit où vous avez enregistré le fichier de profils aérodynamiques, sélectionnez-le et appuyez sur Ouvrir.

Entrer la longueur de la corde

Une fois le fichier de profil sélectionné, une nouvelle boîte de dialogue apparaît et vous demande une longueur de corde. Vous pouvez saisir n'importe quelle longueur, en millimètres. Une fois la longueur souhaitée saisie, la macro produira une Draft polyligne (DWire) suivant les points décrits dans le fichier de profil .dat précédemment sélectionné à l'échelle que vous avez saisie pour la longueur de corde.

L'aile, optimisée, devrait maintenant être prête à être utilisé dans votre projet.

Utilisation - Version 2

Sélectionner le fichier de la même manière que la version 1.5. Avec la version 2, vous avez le choix de disposer soit de l'aile qui en résulte fait avec une Draft polyligne (DWire) ou une spline de base (BSpline). Comme avec la version 1.5, vous entrez la longueur de la corde désirée. En outre, vous pouvez maintenant sélectionner quel type de papier souhaitée. Il suffit de cliquer sur la case d'option BSpline ou laisser la valeur par défaut DWire.

# This Macro, when run, will first provide the user with a file browser to
# locate and select a .dat airfoil text file. Once selected, a chord length is
# entered and upon pressing the OK button, a properly scaled airfoil is
# produced. There are two versions provided here. Version 1.5 should work on
# FreeCAD versions, 0.13 stable as well as all 0.14 versions. Version 2 should
# only be used with FreeCAD versions equal to or greater than 0.14 3077 and
# will work best with versions built with OCE/OCC versions 6.7 or greater (See
# the Wiki page for all available version).
