4. When defining the Hole Set, select the holes to drill. Assign values to the cycle references and variables that do not have a value. For more information on assigning values to references and variables, follow the link under Related Links. The references and variables are listed in Cycle References on the References tab.
5. Define the drilling depth of the cycle references. For example, if the hole depth is Auto, the start surface and end surface are determined automatically; if you use another depth option, you have to select a surface or specify a Z offset for each of these references. For information on how to define depth, follow Related Links.
