I have found very nice scenery of Detroit airport (DTW) and found a AFCAD for the scenery, but when the planes land on the new runway at DTW (runway 04L/22R) all the AI planes taxi in the grass to the terminal. I tried re-making the taxi lines so the planes would follow the taxiway, but that didn't help. The planes still don't follow the lines I made (they didn't follow the lines in the original AFCAD either)Any ideas on why the planes are not following the lines in the AFCAD? Anyway to get the plane to follow the lines?

Ok I don't know why but the runway exit that the AI planes were using was causing the problems. Whenever the AI planes used that runway exit they would taxi on the grass, so I deleted that runway exit and made the AI use the next one down. It seems to be working now, cause I just watched 5 planes land and they all stayed on the taxiways. Although I did notice that the big planes went off the end of the runway alittle now, but they still stayed on the taxiways when coming back.
