Blend problems

[Anautics]

Hello,

I created a section of airplane wing from two sets of co-ordinates (top of wing and bottom of wing). Then, I imported this sketch of a wing into a part file in two separate planes. I then tried to blend the two sketches together but it failed to regenerate?

Thanks

There were a number of problems.

No trajectory. A straight line between the two sketches

The sketches has overlapping geometry at the trailing edges. I dragged points slightly so they now shade in when the blue arrow is active.

There was a chord line in each profile sketch which I changed to construction.

Working file attached.
