Finishing threads started with 2016 thread tool

So I've been playing with the SW 2016 thread tool.

I want to know how others are handling the finishing off of threads created with this tool.

I've got my custom profiles setup - but the 2016 tool doesn't offer any options for lead-in or wash-out, which is important for me to capture as we'll be using these thread models for Abaqus simulation.  Trying to capture thread washout and accurate geometry of male/female members.


What kind of workflows have the rest of you developed for "finishing" threads created using the tool?



For washout, I'm currently using a variable pitch helix, and tying it to the profile using equations.

For lead-in, I just drew a profile and used equations to set the chamfer depth to .01" deeper (per side) than the minor diameter.  This is representative of our thread cutting practices.


I went this route because I wanted to keep things parametric.

It was a little clunky to setup, but now I can change pitch/diameters easily and it all updates.

One caveat - since I used the intersect tool to create one of the sketches, when I go to a finer pitch than the original SW does create extra sketch entities which I do have to go in and delete.  But that's a pretty quick and easy thing to deal with.


E.g.: example file attached of a buttress thread I was playing with.
