I’m continuing the work on my layout and have decided to add some portals at each end. I’ve done a search of the forum and couldn’t find the answer to my question.
   
Once of the portals in 2006 looks like a tunnel, which gave me the idea to use it as a tunnel thru a mountain. However when I place the portal and build up the terrain around it the portal gets filled in.
   
Is there a way to use a portal as a tunnel?
