Now I don't know much about making scenery objects for FS but I thought this was interesting. Tom Gibson over at Cal Classics describes a program that can be used to convert objects made with Google Sketchup to where they can be used in FS.
Yo're welcome Kevin. I've fiddled arond with GS some in my work and yo can do some pretty neat things with it. Jst be interesting to see how it translates to FS
