Adding buildings

[brettt777]

I have two related questions. First, how are buildings and such added to CFS2 and can the add on ones be made "blowupable" like some of the hangars and towers in the original? I have some pretty cool scenery add ons for CFS2 but the buildings are pretty scarce and what is there can't be damaged.
Second, How do you add custom buildings to FSX? I have G-max and know pretty much how to create buildings and all, but not sure how to add them to FSX. See, I work at International Jets here at Gadsden Regional KGAD in Alabama. There is a building on the airport in FSX that is in the right place but I thought it would be cool if I could somehow replace that building with a G-max model of the correct size and shape. Maybe even add a few static L-39s sitting outside. Then all the guys that have Lotus' fine L-39 can take them there to get serviced LOL.
