two different models of the world map
I tried to see some benchmark images from Google and decided to do the modeling from the two images that I chose
the model was created from autocad rendering preview via 3dsMax vray.lighting and objects such as seats, walls and floors are only additions when showing the shape of the models
I also included the basic object lines from the autocad file to make it easy to re-modeling through each of your mainstay programs. For example in 3dsMax we can also add modify 'sweep' and choose the profile shape you like.I didn't give 3D objects Chamfer or Bevel to provide simplicity of shape.
