"Centerline cannot be tangent to profiles!" while lofting between three profiles

[Anonymous]

 I initially did loft with only the top and base airfoils with one sides of the coil as the center line, but the shape turned out incorrectly: the middle section of the blade was smaller than both the top and bottom ones. So I decided to do add an profile in the middle. But, as you can see, while I was trying to loft between these three profiles , Fusion 360 gave me this error "Centerline cannot be tangent to profiles!". What is the problem here? Is there any other way to do this.

That error message is sometimes AD speak for "somethings wrong, but I don't want to tell you what"

In general, I would suggest making your profiles normal to the centerline rail.  You can do that by creating a "plane along path" and putting your sketch on that instead of the offset planes your using.

Thanks for replying, but I'm still getting the same error after I created the plane along the path and rotated the profiles.

Does this work for you?  I moved the bottom profile so it was coincident with the edge, then used a sweep with twist angle

This works perfectly! I didn't even know that there was a sweep with twist option. Thank you very much!
