If you are having problems inserting a curve by x,y,z then try saving your .xlsx to a .csv and then saving it as a text limited file. For some unknown reason when I exported from an xlx file to .txt it said invalid file type in Solidworks.
This video was originally created as a tutorial for a class where the students were comfortable with those concepts. If there's demand, I could go further in another video.
Alex Ames it would be great to learn how to change the angle of attack. I'm trying to figure out how to design a wing for a formula student car and knowing how to do this would be great :)
@@stillyslalom1 could you please check these? They are the coordinates for a cam of a camshaft system, I've been prompted with the "3d spline curve is self intersecting" and also "at least two adjacent coordinates are identical or too close". What is too close? pastebin.com/6RMjqVwv
Forget about it, the only problem was that Solidworks does not recognize the decimal divisions as commas (,), just as dots (.). That was all that needed to be fixed
Soham Yerandkar my problem was the system settings, I had commas as decimal dividers and the coordinates had dots. I had to change that and everything worked well after that
What I divide the column in excel, it doesn't count the negative numbers: it says #FIELD! instead of negative numbers. I don't know how to solve. Could you please help me?
You could import an airfoil coordinate .dat file to XFLR5, set the flap angle (within 'Direct Foil Design', 'Foil' -> 'Set Flap'), export the modified airfoil, then import that to Excel. If you need to change the flap angle repeatedly, best to just do that within Solidworks.
i have this problem too. Put your data into Excel, use Text-to-columns, and save as a CSV (comma delineated) file. Then rename the CSV to a .txt file and select to use notepad as default program. Then you can import the txt file into Solidworks with no issues.
Create a Solidworks drawing of your airfoil & set the drawing scale as 1:1. Print the resulting drawing without "fit to page" or any scaling. Measure a known feature on the printed page to ensure your printer's scaling is accurate.
@@stillyslalom1 hey thanks man. I’m in my last semester of engineering design for my ME and I’m the airfoil and control surfaces guy for our Design, Build, Fly team here at UWF
@@stillyslalom1 have any tips? Our wingspan is 6.6 ft with a little over a ft of chord length. I managed to cut a decent prototype out of basic eps foam from Lowes. I’m going to use 4 light weight spars to help support the foam. Going with a Clark Y design
@@TheC130navigator Foam is cheap - make a few copies of the wing & don't be afraid to do some destructive testing of the plain foam profiles before you decide how much stiffening they need. High-lift devices will be really important in getting your plane off the ground within 25' under heavy load. I don't envy the powertrain team's tradeoff matrix.
@@stillyslalom1 I was gonna use a modified undercamber Clark Y. We need to get off in 25’ but a Sigler profile is too thin to support the weight of the motors. I plan on using flaps to help increase lift. What do you think and how would I prove the design without a wind tunnel?
Any real wing will have finite thickness at the trailing edge, so it's fine to close the contour by drawing an additional line between the two endpoints in your sketch as long as the gap is small. If you're designing a wing that'll actually be built, consider the minimum allowable thickness of the material you're using and make sure your trailing edge satisfies that restriction.
As a starting point, find a handful of commercial aircraft similar to what you're designing and see what airfoils they use. This site has many: m-selig.ae.illinois.edu/ads/aircraft.html
This is normal for NACA 4-series airfoils. For a quick fix, you can just add a line or semicircle to close the gap. Remember that the trailing edges of actual wings also have finite thickness - nobody's out there shaving off the last few microns until their trailing edge doubles as a kitchen knife.
Use the units that are customary for your field, or the units used in practice by your coworkers and collaborators. The course for which this video was made is taught by an ancient American aerospace engineer, and he prefers inch-pound-second.
If you just need a rough outline of a wing, "Features -> Extruded Boss/Base" will suffice. If you want the root and tip to have different dimensions or orientation, you can define an airfoil on both the root and tip planes and loft between them. An actual detailed wing design can use that lofted surface to constrain the dimensions of individual aerostructural components (skins, ribs, stringers, spars, etc.)

it actually worked
thanks bro
Still having an issue inserting the text file into solidworks. "file name entered was invalid, not found, locked or of an incompatible type"
fixed it by adding ".txt" to the end of the file name
@@platanomikeyklk1455 This actually worked. You saved me so much frustration
thank you so so much man! i couldn't think of any way to make such a chordline
What an excellent video! Just what i needed, thanks a lot!!!
TQSM solved so many problems for me. Really appreciate it
Awesome! Super straight forward Thanks!
ty!!!!!! very very helpful i had no idea i could do the curve feature with the coordinates!
Thank you for sharing.
Usefull and helpfull information
Very good explanation. Thank you.
thank you. im really appreciate this video. finally i got A+ for my airfoil design naca 4415
Worked perfectly. Thank you.
Crisp and clear😌.Thankyouuu !!!
Thanks man, amazing video.
Thank you a lot you saved my day!
I am coming over and over back to that video
Thanks! I needed this!
Very useful video thanks!
for error messages make sure there is no 2 point on data "1.000.000 " and data align on column .txt
Make sure to click on the airfoil and make it fixed so when you find the chord length it doesnt change the shape of the airfoil.
Is it possible to draw undulation in river bed from excel sheet?
perfect thank you so much.
Hi there I'm having an issue in that my points are too close what would you suggest u do to fix this issue?
how can i find the mean camber line of an airfoil in solidworks??
Thank you for sharing
Thnx! great video :D
how do we use the imported airfoil cross section to build a wind turbine blade?
how can i find the mean camber line in Solidworks?
This is great thanks! My excel doesn't have a data tab though. Is there a work around for that?
What version of Excel do you have installed?
Thank you so Much.
Thank you sir🙏
Awesome! Thank you
By doing that thing you explain to size the chord, I'm not changing the geometry of the airfol at all?
Right, imported splines maintain their proportions after translation/rotation/scaling.
very helpful video
Thank You very much.
very good thanks😀👍
Thank you 🙏👍
Thank you so much!
Thanks mate!
Is there a reason that every time I do this and try to import it, it keeps saying "File name invalid, not recognized, or type not compatible?"
I had to delete an empty row at the end of .txt file. That saved my problem. I know u had problem 7 months ago, but maby it helps someone else.
Thanks sir
Hey, I don't understand why the video ends?! Do you not go on to change the angle of attack/extrude the shape? Thanks :)

How to calculate cl of airfoil?
What I divide the column in excel, it doesn't count the negative numbers: it says #FIELD! instead of negative numbers. I don't know how to solve. Could you please help me?
Select your data --> STRG/CTRL + H --> replace "=" with "-"
Thanks bro but I need the full wing if you can
Essalam merci beaucoup
what do i do with the copy of the foil that is like super small. delete it?
Is it labeled Curve1? If so, that should be okay to delete.
be careful of the double points in the text file, in solid work it does not recognize it.
Nicely explained but how to add a trailing edge hinge flap to 2D airfoil??
You could import an airfoil coordinate .dat file to XFLR5, set the flap angle (within 'Direct Foil Design', 'Foil' -> 'Set Flap'), export the modified airfoil, then import that to Excel.
If you need to change the flap angle repeatedly, best to just do that within Solidworks.

when i am importing naca0018 profile it is a bit open where trailing edge should be, how can I close it without disturbing the naca0018 profile
airfoiltools.com/airfoil/naca4digit - you can use a modified thickness distribution coefficient a₄ to close the trailing edge
what u use on keybord when u make chord and forward lines is perpendicular
Shift-click or ctrl-click to select multiple features.
@@stillyslalom1
Thanks for your response my friend
I tried importing the text file into solidworks but I get an error telling me the file is invalid. What am I doing wrong?
Can you paste the text file into Pastebin or gist.github.com so I can take a look?
Hey, I have the same problem. Did you solve it?
can u tell me how to make coordinate of blade from the geometry? Thank you
What do you mean? Are you trying to extract airfoil coordinates from a Solidworks part, or something else?
helo sir
actually m trying to make airfoil NACA 0012, but it shows file incompatible type

Weird, when I imported the coordinates, the pointy end of the airfoil does not connect, there is a small gap there..

@@stillyslalom1 ah I see, thanks for the reply, didn't expect to get a reply from the author himself 🤭
God bless you you beautiful bastard.
You should be modeling in mm, gram, second* accuatly :) those are the ISO units
Use the units that are customary for your field, or the units used in practice by your coworkers and collaborators. The course for which this video was made is taught by an ancient American aerospace engineer, and he prefers inch-pound-second.
You should be modelling in m-kg-s actually. SI units.
my first column is not blank
Dont put any spaces in your file name. It wont upload with a space in the file name to solidworks
Bro,where is the wing? This is just the Aerofoil only
If you just need a rough outline of a wing, "Features -> Extruded Boss/Base" will suffice.
