Thanks for your reply. I had the feeling that I had to split the VRML file
into smaller files but was hoping that an alternative method could be used

I will let you know if I manage to find out another way.

Engineers think that equations approximate the real world.
Scientists think that the real world approximates equations.
Mathematicians are unable to make the connection...
