Getting scenery into an AFCAD mod'd airport

Hi Guys,
I got a copy of AFCAD, and started playing around with my local airport (KACY). I added parking, gates and a new, bigger runway. After I saved it, I gave it a try and none of the new stuff showed up. I read thru the AFCAD FAQ's and found that it'll add the invisible elements of things, but NOT the scenery itself.
Well, a nice long, wide runway won't help much if you can't see it. SO, how do I now add scenery to make my changes visible? Please write any answers in the "For Dummies" format. In other words, like you're talking to someone who has no idea if what she's doing.
Thanks guys. Take Care.
