Realistic buildings for use outside FS9

If anyone is thinking of making an airport or airfield that I have already made for FS9, and wants to use the buildings I have already made (if it is even possible in X plane, P3D, etc) then email me at rogwen@rogers.com. It irritates me and seems to be a total waste of time to make an airport that doesn't look at all like it does in real life if a bit of work would make the FS9 realistic terminal building actually function outside FS9.
