Getting threads right

Tru7h

I've seen the discussions on how to make a thread in 60 seconds and read the how-to, but I'm still not clear on how to tell OnShape exactly what thread I want. For instance, if I want a 5/8-32 thread (oddball, but a good example), what options in the Helix tool do I use to make that happen properly?

You will start with a .625in diameter helix and a pitch (drop down menu) of .03125
Then sketch the threadform, dimension for the minor diameter and sweep. 

Pitch value was calculated like this:
32 TPI (Threads per inch) 
1/32=.03125

I hope this helps.

Making threads in Onshape is far too time consuming. A thread tool addition to this program should be a necessity, when will this feature be added???
