I opened an old assembly drawing and changed the hole location on this part.

I noticed the cosmetic threading didn't move with the holes and found out they were just drawn in.

Then I tried to show the cosmetic threads and found out I couldn't...

I made sure the cosmetic threads will be visible by turning on these two view things.

Then wen to the manager pane and tried to Show/Hide the Hole threads... but the option doesn't exist in an assembly drawing as it does in a part drawing.

So.... Is there some reason why cosmetic threading wouldn't be shown in an assembly drawing?
