I've read through tons of topics with the word "landclass" in it.

Ron? Ron Alderfer of our old ProPilot days? Is that you? Nice to see you back here. And making the sim world better as before. By the way, some of us oldsters still get together occasionally in the ProPilot forum for the odd joke now and then.It is pretty easy to change things in FS compared to ProPilot. The very, very long topic pinned to the top of this forum will give you some valuable indications as to tools and other information. Generally, you can use programs like EZ-Landclass by Russel Dirks or SBuilder by Luis S

Luis,Yes, my old friend, it is the same Ron.

Great news, Ron. By the way, and excuse me, but you can probably find a more recent and complete copy of SBuilder for FS9 on Luis S
