A completely new approach to the machinable geometry and the resulting operations has been developed for VISI 16. The old “operation manager” has been replaced by a more functional “CAM Navigator” double tree. The first tree has the main objective of organising the machinable geometry offering functionalities such as: drag & drop, sorting, filtering, duplications, deletion, element property changes, and many others. While the secondary tree contains unique operation information such as: current machine, current tool-crib, CAM setup status, CAM setup origin translation / rotation, merge of operations, sorting, deletion, drag & drop, and many others.
