These are a series of objects added to the project.  Some of them may be stock objects and others come from third party libraries.  We want to know which libraries are used so that we be sure that we have them installed in the Simulator or tell other folks which libraries they need.

1. Select the Lists Menu
2. Select Libraries Used

This shows only objects that come from third part libraries.  In this case there are four libraries that are used.  The blue line shows that this project uses:

1. add_dwag_hangers.BGL
2. add_SeevKahn_Trees.BGL
3. AN 2 Vietnam Green.Bgl and
4. lens ez airport objects vol1.bgl - this last one has two objects

If you want these objects to show up in sim you need to make sure that these libraries and any associated textures are in an active scenery area.  If not then they will show up in ADE but not in the sim.
