3D modelling for TWL2000
 

Was doing some 3D modeling for my Rule the Rails layout and found out Google Sketch-Up works directly with Google Earth and you can do 3D models of cities which is great for the game.

I myself love Sketchup for modeling, though I've never gone the route with Google Maps. Never really had a purpose to use it, though I guess T2000 can push me in the right direction.
