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 ADD-INS button on rib.

2. You should see Airfoil_DAT_to_Spline_v1.8 script in My Scripts.

3. Click on Run button.

4. AIRFOIL PARAMETERS dialog window will appear.

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

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

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

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

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


Please note that sketch and construction plane will be automatically renamed. It will help modeler to find needed sketch during further design. Name consist from airfoil name following by scale coefficient. 

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