Basically I want to thread end of shaft in Qcad.
Searched under "thread QCAD" and I find plenty of forum "topical threads" about any given topical thread, but nothing about M20 or UNF etc etc threads.
It must be tagged to a menu item which I can't see, but not for want of looking.
Thanks.

Thanks.

Have a look at the image I've posted above. That's how you typically represent a thread in CAD. In the dimension label, you then type the specifics about the thread (e.g. M10 for a metric thread with a diameter of 10 or UNF. You also see drawings with a leader pointing to the thread with a label "UNF":
Are you thinking about drawing the actual thread lines? If so, don't. The images I've posted show how to draw a thread in CAD.
