Greetings all!

I am known as BearDrummer (or BearDrummer1970) across the internet. I am looking for information on AutoREALM, so I can make maps for the RPG's I run for my kids. My biggest problem is trying to find out how to make a circular wall. The capitol, which is where much of the game takes place has a series of walls built in a circle, the smallest enclosing a few acres, the largest a few square miles... Any ideas would be appreciated!
