The Cutter Manager (Figure 1) allows you to activate, deactivate, and configure cut marks and settings for your cutters. You can open the Cutter Manager by clicking File > Manage Cutters.... Your available cutters are listed in the Cutter box.
A list is displayed of all the cutters supported by Onyx. You can click Select All to activate all cutters, or individually select a cutter to activate it.
In the list of supported cutters you can choose to deactivate them by clicking Clear All. This will deselect all cutters, or you can click to deselect them individually.
