Moving/editing default scenery

[marklogsin]

I finally got involved with AFCAD and fixing up a local airport that has been revamped since FS2004 came out. The runway is longer and rotated about 10 degrees. Now, since fixing it though, autogen trees are on part of the taxiway. How do I delete or move these? I got the autogen SDK but I'm just lost. I can't even find the right bitmap to open in the SDK (if that's even what I'm supposed to do). I also want to move some airport objects, like the fuel pumps and maybe add some buildings. How does this work? If I would add a new building, would the default one show through? I need tons of help. It's MO6. Thanks.

P.S. What about texturing an airport? How does that work? The real airport has "Washington" painted on the ramp. Thanks again.
