Hmm. Ok. Think I found why I have a problem with the import. I just realized that what I ended up with was a literal "shell". Your extract, invert, etc. does the same thing. I need it to not just be a flat surface, but a solid. And, that is where the problem comes up. How do you get, once you have the extraction, from a "flat" single surface, back to a solid object, with the same curvature on both sides?
Finally worked out a way. Had to extract "twice", along normals, once out to 0.2, a second time out to 0.19. I inverted the second one, then selected the "blank" sides (i.e., the parts missing geometry), and bridged them. Really which bridge worked, somehow, with multiple faces some times. Also.. Maybe someone can come up with an "extract solid", which adds some set "thickness" to a resulting solid object, instead of just extracting a surface. Wings isn't exactly a surface modeller, so.. in some ways its actually kind of ironic that, in the case of this one command, you end up with a surface (which then becomes damned hard to do anything useful with... lol).
Oh, found a way around the "twisting" effect of circularize too - just make a sphere that is the right number of sides to begin with (duh!). Completely forgot that setting was even there.
But, for the sake of understanding what I meant with twisting (adding extra cuts, then edge loop + circularize on each of the new circumferences), I will post an image. Note: This does not happen if you only add "one" extra slice to the sphere (I tried that first, to see what the result was, and nothing got twisted). It only takes place if you add two, or I assume more, of them. Somehow, it seems to be able to keep things lined up with one, but when you stick two in there, it no longer keeps each of the loops the same.
