Why can the operation defaults and operation libraries be set from the control definition?
A. This lets you maintain sets of toolpath and operation defaults for specific controls or machines if you wish, as well as different sets of operation libraries. When you select different machines or controls, the different sets of defaults are also automatically selected. Note: You can override this on a job-specific basis by selecting a different set of defaults in the Machine Group Properties for an individual machine group. It is important to understand that the values for the operation defaults are stored separately from the control definition. Operation defaults are stored in a .defaults file. This lets you use the same set of defaults for all your controls and machines, if that is all you need. The Control Definition Manager just gives you a convenient way to access them.
