Airfoil DAT to Spline

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:

A propos de cette version
Version 2.0.0, 07/07/2021
Added:
Added processing of Lednicer DAT format (v2.0)
Added angle of incidence (Aoi) parameter, fixed orientation on XZ and YZ planes (v1.8)
Bugfix in comma-separated value files (v1.7)
Processing of comma-separated value files (v1.6)
Unlimited chord length for 1:1 scaled aircraft (v1.5)
Fixed bug on Mac OS (v1.4)
Offset X and Offset Y parameters (v1.3)
Scale Y parameter (v1.2)
selection of construction plane or origin plane (v1.1)
This is a nice and simple app that is useful for quickly creating airfoils.
Unfortunately, for bigger projects that must be modular and that must be modified, parametric variables do not seem to work. (the geometry is not updated according to the user parameters) Definitely a feature that must be added !
Are you on Windows? On my Mac the installer put the files in the 'Application Support' directory right next to other working add-ons, but I cannot see it in the add-ins menu. The manifest says it's of type script, but it doesn't show up under my scripts. Does it show up as a script for you?
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.
Probably too late for you, but I was able to convert a DAT file into a CSV file that the ImportSplineCSV script could use. Here is the top of the included DAT file: MH45 1.0000 0.0000 0.9998 0.0000 0.9995 -0.0000 0.9992 -0.0000 0.9989 -0.0000 ... To make it a CSV, I changed that to the following. That script wanted points in 3D space, so I added a 'column' of zeros. 0, 1.0000, 0.0000, 0, 0.9998, 0.0000, 0, 0.9995, -0.0000, 0, 0.9992, -0.0000, 0, 0.9989, -0.0000, ... You could simply do the opposite to convert your CSV into a DAT file.
I saved a DAT format file from 'Airfoil.com'.
But I'm faced the Error like Figure.
See proper format of the DAT file here. https://forums.autodesk.com/t5/fusion-360-api-and-scripts/airfoil-dat-to-spline/m-p/7862870
Unlike other Airfoil tools for Fusion 360 this one actually does what it's supposed to do!
it works perfectly at first try. Thanks!
Thanks for the great app!
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?
👍
Have been using it since first versions. Works great and keeps improving. Thanks a lot!
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!
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.
👍
Many thanks for this nice feature, it works great. And the Support was very fast and helpful. Thanks a lot
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
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.
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
It works great, it saves me a lot of time. Thank you for sharing.
Thank you very much, really helpful!
Works very well
Really works Thank you
