Nobody is saying the 3D model affects the FDM - that's not the point.
Reading some of the replys it seem to me that it does

Note that 3D modelers will not know where the CG is. That is not an option for pure 3D modelers.
One would assume that anyone who is making a 3D model of an A/C knows
something about A/C and how they behave.If not they will soon find out
when they put the A/C onto a sim and it flys backward or upside down.I
would think that what they would do then is move the model around untill
it looked like it flew like they imagined it would.If they had never seen an A/C
or seen one fly(hardly likely) them they might be quite happy if it was upsidedown
as they would not know that this was incorrect.
So what is the discussion the CofG is where it is and it is upto the 3d modelers

Exactly. Read my earlier long post "Aircraft Frames and Reference Points". Trust us (myself, Jim, Tony ...), we've looked at this situation 'til we were blue in the face.
to make it appear to fly right.
