I'm under WinXP ;-((
Can you give me some references to the documentation of vrml? I think 
I'll have to prepare my surfave grid better (triangles) or something 
like this and not independent lines in x and y direction.
When I've seen it right, the coordinate in the vrml file are not in real 
UTM coordinates. Can you give me a hint how to prepare my data so that I 
can include it manually?

I think I can wait! The next few moth I will not have too much time to 
create 3D models. First one week of caving somewhere in France and in 
Februar is already the next expedition scheduled.
