Airfoil DAT to Spline

Airfoil DAT to Spline




All aircraft developers struggle to make airfoil for wings, tails or propellers. A manually created spline will not guarantee precision of shape. Airfoils are represented as a set of X and Y coordinates in the DAT files. These coordinates should be multiplied on wing chord to get real X and Y coordinates of all points.


This script automates the creation of spline on selected construction plane or origin plane from any DAT file with defined chord length.


DAT files could be found from following sites:

    Have been using it since first versions. Works great and keeps improving. Thanks a lot!

  • Airfoil dat to spline
    Kalle Ström | marzo 15, 2019 Descarga verificada (¿Qué es esto?)

    Super easy to use and build up wings with. The airfoils get a bit big and slow things down so i recomend to use this with  airfoil dat optimizer.

    Super work! Thanks a lot!

    Can you add review on Airfoil DAT Optimizer script itself? Thanks!

  • Import airfoils in .dat format

    It works very well, but make sure you have a plane selected otherwise you get an uninformative error message.

    I do wish that I could import the airfoli into an existing sketch instead of having a new one created.

    Also, Fusion 360's performance with this large a spline can get pretty bad so put it where you want it and do everything else around it.

    As many users as many preferences. However, I agree that performance of Fusion 360 degrades with a lot of vertices. To avoid it I have separate (not published yet) script which optimize DAT file and saves it as separate one with minimized number of points. If you like to test it, drop me an email, I'll send the script for manual installation.

    installation works well, application is very helpful, it will replace other airfoil processing apps

    Klaus, thank you for tests on Mac OS platform. UPDATE Dear MacOS users, Please read following thread on forum. Thank you!

    Klaus Kreis | enero 10, 2019

    the .dat file has to have the correct header line, correct decimal and field delimiter, in the worst case I used a normal line editor available on my mac to correct the format.

    Hi Sir, It means you successfully installed it on MacOSx ? I tried on mine using Mojave and I can't see the provided script.... Does the installation is broken on Mojave ? Tks ! denis
