Thanks for the info. I made a first version of this that works reasonably well, at least on the one model I tried it with, but it is not exactly accurate and I'm doubtful if it can be made so. The main problem is that the information contained in the exported .csv file is not sufficient to fully describe the rotation of the airfoils at each point. I have approximated dihedral by looking at the change in mid-chord position relative to the previous section (in yz plane), and twist by looking at the...

Thanks for the reply. I see, that makes sense. I might have a go at generating a wing .xml from the information exported by the program I used to design it (OpenVSP). It exports a .dat file for every airfoil section, and a .csv file to describe the chord, leading edge point and trailing edge point locations (xyz). It does not give any information about how the airfoils rotate gradually (around x-axis) along the wing, but I think I can just interpolate using the location of the neighboring sections....

Hello, I noticed XFLR5 can export a plane design to an .stl file, but I could not find any way to import an .stl file... is it possible? Or maybe there is a third-party converter around somewhere?
