Airfoil DAT to Spline

Airfoil DAT to Spline

Mac OS, English

To create in seconds spline for airfoil from DAT file for further aircraft development.

General Usage Instructions

1. Open Autodesk® Fusion 360™ and click on the ADD-INS button on the rib.

2. You should see the Airfoil_DAT_to_Spline_v2.0 script in My Scripts.

3. Click on the Run button.

4. AIRFOIL PARAMETERS dialog window will appear.

5. Select a construction plane or origin plane to make a sketch on it.

6. Input airfoil chord size, Scale Y, Offset X, Offset Y, and AoI parameters and click the Ok button. (You can use any units used in Fusion 360. The script will scale coordinates from the DAT file automatically.)

7. Open DAT File open dialog window will appear. (By default it will filter DAT files only. Use the drop-down list to select all file extensions.)

8. Select the file with the airfoil you want to build and click the Open button.

9. In few seconds on a selected construction plane or origin plane new sketch with the spline of the airfoil will be created. 

Please note that the sketch and construction plane will be automatically renamed. It will help the modeler to find the needed sketch during further design. The name consists of the airfoil name following by the scale coefficient. 

The airfoil names will be taken from the first line of the DAT file you selected. If there are spaces in the first line they will be omitted from the beginning and end of the line and replaced by “_” character in the middle.





The installer that ran when you downloaded this app/plug-in from Autodesk App Store has already installed the app/plug-in. OR, simply double-click the PKG to install the app.
