How to model a thread created using the hole feature

[cqualley]

I'm trying to create a modeled thread for export as STL for a 1/2" PCV conduit (1/2" NPT). I'm familiar with modeling the threads using the threads tool, but NPT is missing and seems to only be available in the hole feature. I can model a NPT for PCV pipe and fitting correctly using that tool, but it does not appear to model that thread, it's just an image/representation. Solutions to this?

Unfortunately there's no "modelled" option for tapered threads in Fusion. A solution that some have used is to insert a part from McMaster-Carr with a male thread and use that with a combine-cut. It's not ideal and it obviously depends on the McMaster-Carr part being modelled correctly but short of constructing a tapered spiral and sweeping a thread profile along it etc. it's probably your best option.

Okay, that's what I've come to find unfortunately, although those answers were a couple years old. Seems as if nothing has changed, thanks!

Indeed! If it's any consolation SolidWorks doesn't support modelled tapered threads either. I'm not familiar with other 3D parametric CAD applications so can't comment on those.
