I made a cut and divided the STL wing facets into three parts Leading Edge, Upper Tail and Lower Tail and covered the three faceted bodies using the skin tool. Now the two end edges of the upper and lower surface of the wing are not connected to each other, as if in some areas the upper surface is shorter than the lower surface and in some areas it is larger.
All three photos are related to the Trailing edge of the wing. The middle photo shows that the upper surface is shorter than the lower surface, and the right photo shows that the upper surface is longer than the lower surface.
( I will present the second wing.)
