I am trying to do the external perimeter on an oddly shaped part using 3D Area Clearance and "Pocket In - Core" Pattern.

The template image shows the pattern i want but its not generating correctly.

If you look at the top down image attached, my tool path will do 1 perimeter pass from the stock then 1 contour pass exceeding the stepover. Then it treats the remainder as a pocket. What can i do so the tool path will work from the outside in.
