The need for a truly comprehensive set of international (worldwide) threads is long overdue. If this task is too great then the ability to locally store custom threads is of paramount importance. This topic keeps arising so please give it some attention.
I have looked at attempting to create custom thread sizes by editing a thread library using an HTML editor. I chickened out fearing I would break something. How about adding a thread library editor that uses existing standards for thread designs?
I have a potential work around to make an NPT Pipe Tap in Manufacturing module.... For this example I have mad my demo around a 3/8" NPT Pipe Thread.... I made a sketch which had a .675" Diameter circle at X0Y0Z0 I then entered into the Patch Module and extruded a surface off of the circle with a 1.7899° Tapered wall .550" Deep. Enter the Manufacture module (Under 2D select BORE) and then select a 3/8" Flat endmill (or set it to whatever diameter your thread tool will be) The pitch on a 3/8" NPT thread is 18 TPI .... so enter 1/18 in the pitch step box. If you want multiple step overs to reach full thread depth then tick multiple passes and enter 3 with .015" step over per pass. You will need to play with the stock values + or - to get your pipe plug to sit flush on the work piece but i think this might work for your needs until the guru's get NPT added to the list of threads... I have a .f3d file with the example in it i could post but i don't see where i can attach the file ! Let me know if you want the file or need help with what I have proposed.... Brain
I see that this has been implemented according to this topic, however in Fusion, I do not see NPT as an option. Is it named something else? Or maybe its using a European naming that is the same as NPT for us in the States?
Disregard, I was looking under Threads instead of using the Hole tool.
@Anonymous Currently, NPT threads are only present under the Hole command. Change the Hole Tap Type to "Taper Tapped" and you should see the NPT option in Thread Type dropdown.
@rishabh.bisht I'm struggling to get the threads created with the hole tool to be modeled (I don't see the modeled/cosmetic option in the hole tool and changing threads:modeled in document settings does not appear to be doing anything.
Hey @gumert , thanks for reaching out! Tapered threads are only available in cosmetic mode right now. That's why you don't see the option to toggle between cosmetic and modelled thread when you switch to "Taper Tapped" option.
npt only added to hole tool. need to be able to add external threads. What's the point of making a threaded hole if I can't make a threaded part to put into the hole? Is this still being worked on? Any updates on time line would be nice.
External NPT Threads.... Here is a suggestion.....
If you modify the external thread surface and add 1.79° / side draft onto it and then Press/Pull the diameter to the proper size of the male thread feature that you want.... This is the standard draft angle for NPT threads.
Then you can use the 2D Thread function to cut the tapered surface you require.... Set your pitch to to match the thread you are cutting here..... example : 1/11.5 for 11.5 TPI ..... Lots of adjustment to the machining parameters and you will need to figure out the diameter of your thread mill tool to work properly.... But i have done this many times and it works well... I use the "Multiple Passes" option and step into the thread 2 or 3 times to get a good finish on your part....Adjust your plane at the top to be about .050" above the top of your part so you get a good thread start.... Set the bottom plane according to the tool you are using so you don't smash into the bottom surf also.....
But the pressing question is why weren't tapered threads part of the threads tool from the beginning? These threads are included in every thread wizard I've used previously, including inventor.
I don't want to spend time making tapered threads from scratch when it should be basic functionality built in from the beginning.
