Hello,I am not a scenery tech.I have the USS Stennis.It has its own Scenery and Texture folder.Works great.I added an NDB to it using AFCAD2.21 and the saved the resulting AF2xxx file into my Addon scenery folder where other individual AFCAdfiles are located.All shows up ok in MSFS but ... the carrier and the NDB.when I run ScanAFD it show DUPes.Is this a case where it is ok to have a DUPE afcad?

...Is this a case where it is ok to have a DUPE afcad?

You can have several copies of the same basic AFCAD floating about, although it probably slows things down a little.The problems usually start when you have different flavours of the same airport: conflicting elevations etc.Some designers put a stripped-down copy of their AFCAD into /scenery/world/scenery to "lock down" the elevation.

Ok,Thanks for the answer on this.Have a good day.
