I am creating a new Air Force Command and yes I did read the MODENC. I am having trouble with my planes sitting properly on the "runway". This is my code for a 6 dock airfield

DockingOffset0=0,-128,0
DockingOffset1=0,128,0
DockingOffset2=0,256,0
DockingOffset3=256,-128,0
DockingOffset4=256,128,0
DockingOffset5=256,256,0


The MODENC says this:
Art coding

By default, the units dock with the structure in it's exact center point. This can be changed by adding DockingOffsetN=X,Y,Z to the structure's art.ini coding. N is the number of the docking position, and will be used if all the docks with smaller N are used up. N starts at 0, not at 1. X, Y and Z are measured in leptons (1/256th of a cell). The center point of the structure is 0,0,0 and if you imagine a 2x2 structure to be foundated like this:

-A-
BXC
-D-


I understand the lepton being 256 (3), but having problem lining the planes up. In row 1 planes 1 & 2 almost overlap same with R2 plane 1 & 2. I do not see anything in the MODENC explaining this matter an further. And as far as the foundation for the Airfield mentioned in the ENC. Having the docking points outside of the foundation I have found that this has no affect on the planes not returning to base
