Description

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 | September 19, 2021 Verified Download (What's this?)

    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.


  • Fantastic

  • Position in space ?
    marty | November 24, 2020 Verified Download (What's this?)

    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. https://forums.autodesk.com/t5/fusion-360-api-and-scripts/airfoil-dat-to-spline/td-p/7862870/page/2 Someone will help, I believe. Provide all steps you performed with screenshots or results.

    some initial issues, but works now

    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.

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

    Je n "arrive pas à installer, impossible de décompresser le fichier, pourquoi?


  • Import airfoils in .dat format
    Marc Schafer | December 25, 2018 Verified Download (What's this?)

    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.

  • macOS 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! https://forums.autodesk.com/t5/fusion-360-api-and-scripts/airfoil-dat-to-spline/td-p/7862870

    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.
