Airfoil DAT to Spline

Airfoil DAT to Spline

Sistema operativo:


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


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


DAT files could be found from the following sites:

  • DAT file?
    Christian Moser | settembre 19, 2021 Download verificato (Guida rapida)

    Hi Sergey

    Looking at your video and the other ratings your add in must be great. Installation in Fusion worked without any problems.

    Unfortunately I do not manage to create the DAT file. I copy the airfoil coordinates in excel but do not have the option to save as .DAT.

    I can only save it as .CSV but your add in does not allow me to use this file.

    How can I create the .DAT file?

    Thank you very much.

    I saved a DAT format file from ''.

    But I'm faced the Error like Figure.

    Thanks for creating it!

  • Perfect!

    Unlike other Airfoil tools for Fusion 360 this one actually does what it's supposed to do!

  • Fantastic

  • Position in space ?
    marty | novembre 24, 2020 Download verificato (Guida rapida)

    Its works fine on YZ plane, but if I try to use it on a plane at say 100 mm offset from YZ plane, the spline seems to be placed at a wrong position.

    (I use Macintosh version)

    I haven't MacOS computer to reproduce the error. Try to ask your question in this thread. Someone will help, I believe. Provide all steps you performed with screenshots or results.

    some initial issues, but works now

    Sergey Ivanov (Autore) | ottobre 27, 2020

    Hi! If you have invalid DAT file it doesn't mean that application is bad. So, one star also invalid. Just send me by e-mail DAT file and I'll say what is wrong.

    Simon shemetilo | gennaio 12, 2021

    are you sure you put .dat at the end of your notepad save file.

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

  • Airfoil dat to spline
    Kalle Ström | marzo 15, 2019 Download verificato (Guida rapida)

    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!

    Sergey Ivanov (Autore) | aprile 02, 2019

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

  • Import airfoils in .dat format
    Marc Schafer | dicembre 25, 2018 Download verificato (Guida rapida)

    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.

    Sergey Ivanov (Autore) | gennaio 11, 2019

    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.

    It works perfectly ... users wait for the new update

    Ricardo, stay tuned. Version 1.6 is comming... ;)

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

    Sergey Ivanov (Autore) | febbraio 02, 2018

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

    Klaus Kreis | gennaio 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.

    dbrondy dbrondy | marzo 03, 2019

    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
