The Apply All and Apply options in the Cutting, Punching and Combination Material Information windows allow you to update the material file parameters for the active part or the entire sheet. If you process while Part view is active, the software only updates the active part in the work area. If you process while Sheet view is active, the software updates the attributes for the paths. Only those parts having the Keep Attributes option enabled maintain the original attribute settings you defined for them.
The Apply option only applies those changes you have made for the current tab to the active part or sheet without resetting the sequence. For example, if you modified the values on the Lead In/Lead Out tab, and then click Apply, only those lead-in or lead-out values are updated for the current part or sheet.
