Oh and for this object it would also help to rotate the bridge so that it is aligned with an axis. And then rotate it again when placing it in the scenery. Then the bounding box is more optimal.
It can be a solution the rotation, but I have some doubts. The other option to export to xml and then transfer it in FSX, a bit more complicated. There is the problem then do no wrong orientation.
Now I take the data from kml file
<? xml version = '1 .0 'encoding =' UTF-8 '?>

even though I did not understand in what format are inserted
<heading> 0.723643005067 </ heading> I use these
If I measure in Google Earth is 55.67 ° -
But the result is excellent. The object is positioned very accurately without errors.
Sorry for the delay in responding but I have to help with the translated language.
