Russ,
Check out Machinist Toolbox, Machinist Toolbox
One of the many valuable features is Advanced Threadmilling, it will generate the code like the wizards, you can pick single point threadmilling, also NPT threads from the menu and it will input the numbers for the size you want.
The trial is for 15 days and will output the code for this to see if it works for you.
Well worth the $100 though.
