I'm creating an assembly containing a threaded pin that inserts into a ring at three places. In the isometric view, one instance of the pin displays just fine, while the other two seem to be invisible around the threaded portion (created with a swept cut - triangular along a helical profile).
I've attached a picture, circling the three pins. You can see in the unexploded view that the 'space' actually covers up a portion of the ring. I've attached the pin, assembly, and assembly drawing as well.
Unfortunately, I can't simply replace the threaded portion with a cosmetic thread callout, as it's necessary to physically show the thread.
