Hi Evan, Do you mean a specified thread or and actual phyisical cut of the thread. - If the first the the command is Insert/Cosmetic/Thread then use the dialog box or menu to specify the thread (not that user friendly especially for metric). - If the second then you want Insert/Helical sweep. You will have to sketch the length of the thread trajectory then sketch the thread form you want to cut. If you are new to both then you will need to experiment to get what you want. Regards, Brent
