When I found TPI didn't work I remembered Fusion's metric thread XML files used Pitch so thought I'd try it in your XML file.

I was running in a strange Problem those days, maybe you also know more about that, as I have the feeling its something similar as it was here, a little buggy in combination with doing something impossible.
I tried to create a thread similar to BSP G3/4-14, just fith a TPI of 12 instead of 14, So I copied the BSP.xml file, deleted everything from it, that is not a G3/4 thread, copied that thread section and changed the TPI to 12.
Result is, I get the thread as desired, but if I select formed, the thread is a trapezoid and not that rounded thing that A BSP should looklike.
Same if I do it for the just copied G3/4-14.
On the other hand, if I select the G3/4-14 from the standard BSPPipeThread.xml then the thread has those fancy rounded endings as a BSP Thread should be.(I asume WithWorth would be the proper selection for <ThreadForm>).
So I checked the standard file, It does not set <ThreadForm> as my custom as a copy also did not.
So I did set the value with the result, that I can see a change for selection 1 and 5 (sharp and squaric), but 0 and 7 (trapezoid and WithWorth) do result in same Trapezoid optics.
So I have four main questions:
Am I doing something wrong?
Is there a bug causing this?
How does fusion know for the standard BSP Threads, that they have the fancy rounding?
Do you know more?

I tested through values 0,1,5 and 7 for ThreadForm, but never got the fancy roundings as the BSP should have. I also tried to not set the value at all
