Peregrine Falcon,

Firstly, thank you for replying so quickly.

If I understand you correctly, in point #1, you are suggesting a "floating" tunnel system? Interesting. I am sure that this is not what a tunnel is designed to do. But, what the hay, it's good to think outside the box.

I am trying to create a "tunnel only" map, and if your idea works, it will solve any annoying problem. I will try it and let you know. If I get it to work, I will post a test map. (my mapping skills, and I use the term "skills" VERY loosely, are far from average. I dream of average.)

Thanks for the assist.

Regards

J
