I just happened to know from the Autodesk Powermill website about toolpath Editing History and optimization which seems powerful in the Selection and Deletion of unwanted toolpaths without the need to redraw the boundaries and regenerating them .
This Ability will reduce the dependency on recalculation of toolpath . This ability in powermill seems amazing . For more understanding please have a look at the video in the below link
