This is the easiest and most accurate way I have found to create airfoils in Fusion360, and it has been working great for me!

Interesting to see questions to blogger instead of asking the developer. This is my add-in. By now it was upgraded several times.
a search in RUclips of how to model an airfoil in Fusion 360 results led me here. Thank you for your work. You got a subscription to your channel from me!!
I made a flat bottom airfoil once with Inventor using numbers from a table I found online. I set "d0" to be the chord length which is the first "driving parameter" (so you change it and all other points change relative to it) on a construction line in the 1st sketch (bottom of airfoil). Then laid down 10 points roughly in an airfoil shape. Put "x", along chord, dimensions in place at 5% (d0*.05), 10% (d0*.10), 15% (d0*.15) and so on. Then the "y", height, dimensions calculated from the table as a function of the chord (fx) at that chord position. Then establish the LE point and the starting point on the bottom edge. It came out fairly smooth with a few points. I drew it tangent to the bottom line forward and up and around to the trailing edge, then tangent to an angled construction line at the TE... but don't connect the spline just put it near the points. Finally put Coincident constraints between the established points and the spline points (add or delete points as needed), and Tangent constraints on the ends. You can activate a few Spline handles and put dimensions on them too to get the curve you want.
I can't select the construction plane. As soon as the Airfoil Parameters box opens, the construction planes visible at 3:27 on your video disappear from my program. What do I need to do differently? OK I figured out that I need to create a component, select it and turn its origin on.
How do u make it a dat file so fusion 360 can read it
If someone could @ me and explain how do I download the data file from the UIUC database because when I click on one of the data files it just opens like a text file how do I download that onto my computer?
Thanks for the video. I don't have much to say but you helped me out by explaining this, so I'll help your videos get move views by dropping a comment.
It does not let me select a plain, do you know why?
you can either reveal your origin on the left panel, or create a construction plane, and select that as your plane
cant either
Helped a lot for a project I'm working on. Thanks!
Do you have a video where you use an aerofoil but 'twist' (angle of attack?) the blade? Thanks
Much thanks, really saved me time :)
plz help!!! I converted .txt file to .dat file, and opened .dat file at fusion360. "error unknown dat format" what does it mean
I have that same problem
Awesome, great tips! Thanks!
Thanks a lot. Helped me and saved a ton of my time.
I can use this! Thank you Colton.
Thank you!
Great vid man. Thanks for the help!
Where did you get the file full of airfoils to start with??
Spot on question haha.
Thank you for your help!
I have a wing design and a airfoil design, how can I put the airfoil on the wing?
Seems the Mac OS has changed and I can no longer import the .dat file. Notes does not allow saving anything but pdf. Using a PC and importing the file did not work either. Thank you for the video.
HOW TF DO U SAVE A DAT FILE ON NACA Airfoil Generator?!?!?!
It is printed right on the plot page, to copy and paste into a text file.
Ok..been trying for two days.... how do you download the dat files?
I think I have figured out that if you are using the free version of Fusion, it will not let you download dat files into it
I tried it for the free version of Fusion and it works. You just have to convert the .txt file that you downloaded into .dat file, which is simple to do and you can google that)
Thank you Halkow
@@havehalkow plz help!!! I converted .txt file to .dat file, and opened .dat file at fusion360. "error unknown dat format" what does it mean
@@nimuyj You probably did not convert it correctly. Here is the link that I followed for doing that:
www.techwalla.com/articles/how-to-convert-a-text-file-to-a-dat-file
Before uploading it to Fusion 360 make sure that you got a .dat file indeed by right clicking it - properties - type of file (which should say DAT File (.dat))
Do we need the music and full screen of 360 would help
The airfoil parameters box pops up, but it doesn't let me do anything. The stupid arrow pops up, and I can't do anything meaningful to it. WTF?
Great presentation. I've spent the last week and a half creating a 3D organic shape in Inventor and it wasn't easy but it came out very well and is modifiable & fully integrated (WPs, sketches, parameters (approaching 2500), then finally the Loft). So I know what you mean about splines.
I have a few questions regarding the spline generated.
1. Are the spline's points constrained, either by dimensions, grounded or an X Ref?
2. Can a wingtip spline be rotated and repositioned to create washout and constrained to a reference from the root chord?
3. Can a surface be created rather than a solid? These could be the outer molded lines, and inner surfaces by offsetting the original spline, to which ribs and spars can be extruded.
1. No constraints by default, though you can of course add some. The script imports the XY coordinates from the airfoil DAT file, then draws the spline through the points. You could probably modify the script to auto constrain certain things if you felt so inclined (and know Python)
2. You can modify the spline however you want to change the original airfoil shape
3. Yes you can "patch" to a 2d surface. This is how I do my models for 2d CFD sims
Never mind, add in is under the tools tab
Am facing an error which says unknown dat file format
How to sort this out ?
I can't find anyone who can actually answer this. My .dat files are not being accepted by Fusion. EDIT: fixed it by right clicking on source file and downloading directly. Before this step I was using Notepad to fudge a file conversion.
I already tried my Fusion in mac and won’t work, but in pc it’s works, you have any idea why?
Not sure TBH, plugin must be written for PC only I guess?
Just had this work fine on a mac.
Thanks for the info but for a beginner like me one question is left. How do you choose an airfoil for a plane??? There are so many )))))
look at the lift coefficient plots for the airfoils and select one that provides the needed list at the required speed / AoA.
how the fuck do download the dat file in the airfoiltools webpage
If I wanted to model a vortex tube that is used in helicopter particle separators how would I do so? They have 4 blades that rotate around the center close to 360 degrees. You can see an example in step 2 of this website.... www.utvvideos.net/sb-filters-polaris-general-particle-separator-2/ I really could use the help.
Why was this kind of video recorded in a car?
Shhh. Don’t question it 🤫
I don’t have “add-ins” on my fusion 360?
did yo look at tools ?
poggers you are, very poggers
Yeah, just wasted a entire day on this. My ok button will never highlight to be selected in the airfoil parameters
I think if you use the free version, you can’t import dat files of airfoils.
Im having same issue. No OK button
The OK button won't come up until you select a plane for the drawing.
thanks
