How do I create a AFCAD File for FSX?

First off its not an AFCAD file. AFCAD was the name giving to the programme that edited the airports in FS9. There are two programmes avaliable here is onehttp://www.fsdeveloper.com/forum/forumdisplay.php?f=83and the otherhttp://www.fsdeveloper.com/forum/forumdisplay.php?f=82The FSXplanner has an airport seach engine that tells you which BGL file and folder the airport is in i havnt played with the other. You also need a bgl decompiler BGL2xml do convert the BGL to xml for editing and the FSX SDK with SP1A to recompile. Just remember to make backups.
