To create the surfaces, I did not cut the facets of the STL wing. I only drew irregular polygons on the wing with the skintool tool and converted them into surface. I sent a photo of it in the previous message.
(I drew a rectangle on the left side as an example)
Yes, if I cut the facets of the STL into pieces and then created a surface on them, there was a possibility of a gap between the common edge of the side surfaces.
Does the second way to make a filled solid wing that you mentioned (skintool video) require cutting and slicing the facets of the STL wing?
I think YOUR PLAN requires cutting the STL facets into many parts. In other words, the more the STL wing is divided into many parts, the more the obtained geometry matches its STL. There is also the possibility of a gap between the common edge of adjacent surfaces.I am right ?
This creates an approximate shape of the wing and is not exact, and it would be great if there was a way to create a solid body without having to cut the facets of the STL wing in one piece. Is there any hope ?
