Ok well boredom took over and I decided it would be fun to make my own island using AFCAD. Complete with a 20,000 ft runway, 12,000 foot water runway, and a small GA grass strip and 144 parking spaces for the military, airlines, cargo, and GA, it is certainly my airport of choice. And I made the identifier ZACH no less.
But the problem. I drew the "island" polygon out of grass and everything appears just fine above it, all the taxiways and the polygons leading from the main runway to the water, however, the apron polygon (concrete) seems to dissapear. The island is a big polygon of grass with taxiway lights around it. Any help on how I can make the apron show? All made in AFCAD.
