Yes, it is. Stefan

Hi, Yes, the origin of the components is at their leading at the root. You can also double check this using the Z view in the plane editor, offsetting the tail a small amount in Z and then setting the x offset of the tail to 0. You will see that the origins (root leading edges) align. Cheers, Stefan

In the upper left corner of the wing editor is a checkbox that allows you toggle the symmetry of the wing. I also recommend watching Andrés set of tutorials, which cover most of the basic functionality: https://youtube.com/playlist?list=PLtl5ylS6jdP6uOxzSJKPnUsvMbkmalfKg&si=Cw3tu2TIu1abKNVw Cheers, Stefan

As long as the leading edge sweep of your wing is 0 deg the offset is 0 for all sections and this is fine. If it isn't it will change the distribution of the area and therefore impact the pitching moment and some other parameters. It depends on what you want to analyse.

Hi Rebecca, when changing the span of an aileron, you only need to change the position of the inner section, as long as the wing is not tapered. If it is tapered, you need to recalculate the chord length of the section and its offset. The wing area should not change then. Cheers, Stefan

The coordinate system should be aligned with the foil and independent of angle of attack, so there should be no projection necessary. Cheers, Stefan

I suspect the shift is due to viscous and numerical effects, but I would need to look into in detail to say for sure. Are you referring to the plane analysis module or foil analysis module in your second question? Cheers, Stefan

You can export an operating points data by right clicking on it. The export gives you the pressure coefficient for every panel, which you can use to calculate the forces. Cheers, Stefan
