Macro ImportAirfoil/fr

Description

Macro pour l'importation des coordonnées d'un profil aérodynamique. Il est possible, à l'aide d'une simple boîte de dialogue, de mettre à l'échelle l'aile, de la faire pivoter, de la translater dans le plan, de la translater le long de l'envergure, de sélectionner le plan et l'axe principal, ainsi que de transformer la géométrie en une esquisse. Il est possible d'importer des coordonnées enregistrées dans les formats les plus courants.

Utilisation

Exécutez le programme de la macro et suivez les instructions.

# Airfoil import macro
# After selecting the file with the coordinates of the airfoil
# data processing and modeling of the airfoil are performed.
# It is possible, using simple dialog, to scale the airfoil, rotate, 
# translate in the plane, translate along the span, select the plane and 
# the main axis, as well as turn the geometry into a sketch. It is possible
# to import coordinates saved in the most commonly used formats.
# Airfoil import is based on:
