Split

The Boundary | Islands/Lakes | Split command breaks complex polygons into their component parts. Complex areas can be made from areas that are touching or are completely separate, or can even use one area contained completely inside another area. Each individual area in the group is called an island. An example of islands that can form a complex area is the Hawaiian Islands. You can also have one area completely inside another area. This is referred to as a lake. Lakes form holes in a complex area so you can see through the lake to any underlying objects.

When you use the Boundary | Islands/Lakes | Split command each area becomes completely independent of the other areas in the group. The original object's fill and line properties and primary ID are assigned to all the new areas. You can change the new areas' primary and secondary IDs through the Object Manager or the Property Manager.
