I just want to clarify 2 things: 1. As stated in your manual the Lat. and Long. of a node is NOT exact. Is that correct?
Not exactly. The manual says you don't *have* to be 100% precise in setting coordinates, because the node selected will be the closest one to the coordinates you set. You can't indicate any random coordinates there, the point will ALWAYS be an existing node, so the closest one will be chosen, and this also has the side effect that you can probably still do minor changes to the nodes (move them a bit, for example), without necessarily having to reinsert the coordinates in GSX because, if the node you edited is still the closest one, it will be found anyway.
When watching a push back of the Lear it was in proximity of the node but it was NOT exactly on the node.
This is an entirely different issue, and doesn't have anything to do with the "snap" feature discussed above. You must realize that custom pushback nodes DO NOT indicate the final location of the airplane, they are more like control points of a curve (in fact, it IS a bezier curve which is drawn in-memory), see my explanation here for an example:
http://www.fsdreamteam.com/forum/index.php/topic,11083.msg85596.html#msg85596I know it sounds counter-intuitive at first, but this way you can control WAY more path options with just two nodes, because you control the fitting of the curve.
2.: When I was happy with my customized parking editing I clicked on the "Apply" button but nothing really happened. The apply button clicked but it didn't change in any way or there was not a load bar that indicated that the changes had taken place so I assume it saved my changes. Am I correct?
The indication that your changes are saved, is the Apply button that has been greyed out. If it's not greyed out, it means you have unsaved changes in that page.
