A Variable Contour operation is created and is setup to get the desired tool path. When the Non Cutting Moves menu is expanded the Engage and Retract settings are missing. What happened to the Engage and Retract settings?
When the Non-Cutting Moves text was selected in older versions of NX the display did not change. In newer versions a menu is now visible.
Unchecking the Override With Smooth Connections option will cause the Engage and Retract menus to be available.
