cosmic threads

I'm absolutely frustrated.  I've watched videos, read a dozen "how to's", and they all say the same thing. Go to Document properties - Detailing and check Cosmic threads and shaded cosmic threads, and display annotations.... Done, done, and done. I"ve used Stud Wizard, I've just drawn a cylinder and inserted a cosmic thread.  I still only see the  hidden line representing the thread.  How the heck do you make it show the threads???  And just for good measure, I have some older drawings that do show them.

 

 

Thanks
