Hi Christian.I'll look at Oshgosh's raillines, too.It's funny, but I still suspect the design team left us the Oshgosh example as a clue to some of these structures. As I joked to 'georgio', they did it on purpose! :-8

There must be an in-house tool that the Flight Team at MS uses.I found it most intriging that in the LA scenery textures existed for the Griffith observatory but no observatory and the other side of the coin was that as Mike Vernon pointed out, the Crystal cathedral didn't have any textures!I fixed that for him here:http://www.geocities.com/ihor.geo/It shows that the MS scenery designers were rushed in their effort to meet the FS deadline, though they did have time to inscribe their initials on the back of their hollywood sign!
