Yes, every building in the game, buildable or not, has an entry here. It associates a number with a building. Find the end of the list & add your building to it, with a number one greater then the last building.

UIName specifies the name of the object. This is a reference to a name in ra2.csf.

> 3.What's with the icon? NAAIRC should use my new icon (heli2icon)instead of normel heliicon Like GAAIRC use.

No, it should recognize your new icon. Is it SHP (TS)? Is it 60x48?
What do you get in game, Missing cameo? Or just some black space?
