I think it's pretty clear that we aren't going to agree on one
coordinate system to use.
Aside from that, agreeing on one takes away the freedom to choose a
location that makes sense for the aircraft you are working on (for both
the FDM and 3D modeling).
I may not have made myself clear. I'd personally like to use structural frame. However, that's not always available, so we have to come up with something. We really only care about distances, anyhow, not so much exact locations. So, if we agree upon a convention (origin at the nose tip, normally), then we can simply report the CG location in that system and the Euler angles and the model comes out looking fine. So, I think we can agree on something.
