Thanks Chris,
Ok I think I'm getting there although rather slowly I've looked through the tutorials, but I can't work out how to get the floor correct as my floor needs to be at the top of the walls if that makes sense to create the levels, I don't know if I am going about this all wrong, should I not be using walls to create the different 3 levels?
I am really confused!!
Thank you, I hope I am explaining this right!
Tim
