How does the Areo Indicator work?

So now we can press F12 and see an indicator for aerodynamics. Cool. But how does it work? Because I'm just seeing a bunch of colorful lines between my rockets and planes?

The lines indicate where, in what direction and in what magnitude aerodynamic forces are acting. Red lines are drag, blue is lift from lift surfaces and yellow (iirc) are aerodynamic control forces. The length of the lines is proportional to the strength of the respective force.

Nice! Thanks Zuthal-
