Exporting Gmax Scenery to FS

Does anyone know of a good tutorial that tells you you to export a .gmax file into FS?
I would like to build reporting points for the GAAP airfield Archerfield and I don't know how to put them in the right position and export them to FS.
And, yes I have searched with no luck.
