How can I reverse direction for tool containment in MasterCAM?

I want the tool to cut outside the containment boundary in rough pocketing process. Every time I try to perform it, it cuts inside the region. Is there anything I'm missing?

Go to Parameters.
Select your tool.
Choose computer in that other box.
Choose left or right. That is the reference to the
Cutter compensation.... Left or right if the line.
Make sure you check the little blue cross then select
The green check mark.
This happens a lot. Sometimes on multiple parts in the
Same stock set up, you may also have to select a new starting point.
Good luck!
