hmmm I'll have to think aobut it. But no promises.

With the fillet surface ready to attatch to the wind I ran into some issue.

It appeared that the attatch tool did not work. I did eventually figure out how to do this, but do not quite understand what was wrong.

Anyway, the spans running alongside the surfaces were different.
The fillet surface was rebuilt from 26 spans to 22, just like the count on the wing. Stangely, the attatch tool worked this time.

I know the attatch tool did not work with trimmed surfaces, so I undid some easy trims prior to the attatching. I can trim the small things after the attatchment.

I now have a full wing, and I do not intent to attatch it to any object.

Here is the full wing with trim.
