external pipe threads
(OP)
I need to call out external pipe threads on a part I am drawing. 1/4" NPT. I've never had to look it up before, so I don't know what the boss outer diameter should be. Does Solidworks have this info? Do any of you? Once I get the boss to the right dia, I was just gonna do cosmetic threads, but I need the boss size!!

Additionally I have a lisp routine (yes i said lisp) that will produce a profile of any npt thread sized 1/8 thru 1". I should probabally have the lisp converted to sw api or a vb macro. I have run the lisp and saved the acad drawing and then opened the drawing in sw and used the profile as needed. If any one wants it, let me know and I will give it to ya.
