blender & civ4 blender video tutorial

Hello everyone

Has anyone done a blender tutorial video tutorial to download on how to
make a simple object with texture to export into civ4?

Iv been trying hard to make a simple cube in blender to show up into civ4
but i can't seem to even export ,

I want to make a new building and new unit to make in blender for civ4,

can anyone help me ? i find that the video tutorials to download much easier
coz its hard to read on forums, as i have only one monitor,
and the video tutorials, show in real time step by step.

i hope someone can help me
thanks
