I have a 3d carving that has a tree that is cut to a depth of over 1/2". Rather than having straight cut on the sides it would be great is I could give it a more rounded profile using the two rail sweep. Unfortunately, I'm not even sure where to start with such an irregularly shaped item. Any ideas, attached is a file that will show you what it looks like. The tree in question is to the left, the bottom is beach and can be ignored.
