Hello Hagar, I actually figured it out this morning.
Thats great. I'm pleased you're starting to get the idea.

Oh, one question Hagar. In FSSC what does the "repeat" mean on the level editor of the 3D objetcs? Thanks for the time...........
Good question. I'm not really sure about this myself. The only way to find out would be to try it. According to FSSC Help you can mix & match textures for different parts of a building.
Building Object
The building can be used to make houses, office buildings, or airport terminals. Beginning with Flight Simulator 2000, you can use the advanced building style to mix and match many different textures. An advanced building has 4 different levels: the lobby, the floors, the penthouse, and the roof, and each level can be customized in terms of height, texture, and texture stretching factor. You can preview the textures and the scaling that you've chosen using the building editor.
Besides the default four-sided flat roof style, you can also choose the pyramid, sloped, or n-sided styles
The settings change depending on which option you choose. I assume the "Repeat" value determines the way the textures are assigned. I must check this out when I have time.
