Hello and respect,
Thank you for sending the video. Dear Peter, my goal is that, like the first video, the STL wing will be converted into a solid wing with a Filled inside, with the difference that the surfaces and sharp edges are exactly like the STL. Is it possible ?
Because I want to take it to Design Modeler and draw the air domain and subtract the solid wing from it. I think that the second method (video 2) cannot be applied to geometries with different shapes, and the first method (video 1) will be more comprehensive.
I can also provide an STL file that includes the wing and the domain around the wing. Is this helpful?
