I asked for a program the other day that I could use to creat my own airports and you guys told me AFCAD. Well I got it and have created and updated 3 airports so far, works great and easy to use, Thanks again guys. One more question on it though, can you use afcad to make the grassy areas around the airports? I have not seen any instructions on that in the manual. Or is there another program for that?

With Afcad, you could surround the airport with grass 'aprons' but these would probably not blend in with the surrounding scenery very well.

The better method is to change the 'landclass'. This can be done using one of several landclass utilities available.

Here are a few-Ez-landclass(requires Excel), or Landclass Assistant and others.

The other option is to use the landclass tool available within a scenery design program. I personally use SBuilder.

I hope AFCAD2 does the trick for you . . .
Here's what Lee Swordy has to say about Creating Apron Polygons:
"Aprons are expanses of concrete or other material that aircraft can park on or taxi over.  Apron surfaces are not just used for parking areas, they can be used anywhere at an airport that extra pieces of pavement are needed, such as to widen a taxiway for a waiting area, or turn-around bays on runways, or for enlarging junctions.

To select a whole apron polygon, for example to move it as a unit or to delete it, just click on any edge of that polygon (not on a vertex or the body of the polygon).  You can also select a whole apron polygon by dragging a rubber band around it, but the rubber band must enclose the entire polygon in order to select it."
