I have seen alot of AFCAD files over at projectai.com that include what are called overlays. My question is what is the best and easiest procedure to install and use these airports? Kind of anewbie with using ttools but I'm getting better..Any help would be appreciated..Thanks in advance!!JC

1. Download and install AFCAD 1.2.22. Put all the aiport import files from your overlay download into an IMPORT folder, inside the AFCAD folder.3. Start AFCAD.4. Select File/Import.5. Browse to the first file (overlay) in your new IMPORT folder. Say OK.6. Repeat 4 & 5 until you have imported all the overlays.7. When you are done, AFCAD will ask if you want to overwrite the existing airport. Say OK.8. Done!Hope this helps,-- Tom GibsonCalifornia Classic Propliners: http://www.calclassic.com/Cal Classic Alco Page: http://www.calclassic.com/alco/Freeflight Design Shop: http://www.freeflightdesign.com/ San Diego Model RR Museum: http://www.sdmodelrailroadm.com/Drop by! ___x_x_(")_x_x___
