Mike, like I mentioned in your other thread, these are objects created in the default scenery model or by the designer if the scenery has been downloaded, using scenery design software etc.

AFCAD can't create stuff like that - it only lets you create or modify aprons, taxiways, parking and 'simple' things like that (and navaids now as well).

Ahhh

You probably need to turn your scenery settings up a notch or two - dense or very dense.

That's done so people with lower end machines can turn off some 'unnecessary' features to save on FR
