xav, thanks for the pointer, I do agree that setting line opacity to less than 100% looks much better. How did you do it? I searched for ways to do it and all I could find was Edit Properties (right click or highlight 'model' or descendants in the Places' panel. But in this manner I lose all shading.

All in all, what I could achieve was far different from your screenshot. I am using GE version 3.0.0762.

PS. I wish GE would support textures on 3D models so that it could be made to look more realistic.
