I`m afraid its many years since I did anything with CFS1 or the various old tools so its all down to memory. I know that in the past I have successfully created large and small sceneries for many parts of the world from the falklands to korea (including one for Cuba) without any problems

The main reason for scenery not appearing (or not appearing where you expect) is incorrect coordinates. Either for the tiles themselves or for the classlist.
I would suggest trying it without linking the bgls together with patlink (in case the linking is corrupting something) and maybe starting with just one tile block and checking that for appearance before adding the others one at a time.

I don`t even have CFS1 installed these days

Thank you for your quick response. I deleted the linked .bgl files and loaded the entire folder into the cfs scenery folder I had created for the caribbean islands, and it worked. I then re-patlinked all of the files, and they work perfectly now. Not sure what I did any differently, if anything. Anyway, thank you for your response. I love CFS1 (mostly because my computer is older and won't run CFS2 lol), and I enjoy creating scenery and aircraft for it. This scenery is for a Cuban Missile Crisis campaign, and includes southern Florida, Cuba, Jamaica, the Bahamas, and Haiti in its scope. Anyway...thank you agian
