SolidWorks
 

Hi everyone,
I am investigating the effect of winglets on reducing the induced drag at subsonic speed, and I have some problems with designing Spiroid winglets on solidWorks, I would really appreciate if someone can help me in figuring out what is the best way to make this Design .
Thank you in advance

it appears that a 'sweep' will make that, but I am not sure what you're having trouble with.

good luck
