Detail NPT Thread


New member
I need to add some detailed threads to my model in WF. I guess I have to use a helical sweep, right. Does anybody have a good technique for creating NPT threads in WF?

thanks in advance,

Try this. I wrote it for machine screws but it should work for your NPT, just incorporate the thread taper into the sweep profile.

1) Create a shaft at the major diameter of the thread<?:namespace prefix = o ns = "urn:schemas-microsoft-com:eek:ffice:eek:ffice" />
2) InsertHelical Sweep Cut
a) Constant Pitch, Thru Axis, Right or Left Handed
b) Sketch Sweep Profile
