Importing an airfoil

The first thing you'll typically do after creating a new document is import some airfoil data.

Click the "Airfoil..." button in the top left of the window, or select "Choose Airfoil..." from the Airfoil menu. You'll get the usual dialog box to find and open a file. When you've found the airfoil file you want, click "Open" to import the data. The file name will appear next to the "Airfoil..." button, and the thickness and camber of the airfoil will also appear.

Airfoil data files can also be opened directly, from the File menu or by dragging them onto the application icon. In this case a new, untitled document will be created with the airfoil already imported. (This is really just a shortcut: Choosing "New" and then clicking the "Airfoil..." button accomplishes exactly the same thing.)
