ansi 9standards0 code issues - showing threads
 
ansi showing threads
what is the current standard in regards to showing threads on a drawing? i used to show them in a front view or in a section but not when hidden and now i am told that they don't have to be shown at all.
what does ansi require?
i've always been told to show them when visible (front view for screws, section for holes and screws...)
