Use the items in the Add to panel to add the active toolpath to the selected entities:
Click Toolpath tab > Add to panel > NC Program > NC Program to add the toolpath to the currently active NC program. This option is only available if there is an active NC program.
Click Toolpath tab > Add to panel > NC Program > New NC Program to create an NC program for the active toolpath. The NC program has the same name as the active toolpath.
Click Toolpath tab > Add to panel > Stock Model to apply the active toolpath to the stock model and place it at the bottom of the stock model list. If the stock model is newly created (no block has been applied) then the block associated with the toolpath is applied automatically.
