Description
Macro for Airfoil coordinates import. 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.
Usage
Run the macro program and follow the 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.
