Hi, Houseboater:
If I read your questin correctly; There are two ways to leave an island. Easiest is if you have paid for the Pro-version of LazyCam. Then all you have to do is add an offset and key in different values for depth of cuts. If you want a lot of space between your outer perimeter and the island, you could then select the pocketing function.
The other way, and this is the way I have done it before LazyPro. is to draw your dxf with an offset and then select different chains. It is more difficult to leave a larger area using this metiod.
Hope I understood the question, and that this helps.
