How to use ThreadCreator?

I had a hard time creating my first internal threads with ThreadCreator and searched high and low for instructions. Lots of vidoes about how to install TH, but very little about how to use it for internal threads. And what I did find didn't cover some key points.
Please chime in with advice. To create internal threads, what worked for me:
- Create a cylinder with major diameter the size of the screw/bolt you wish to thread into your internal threads. I wanted M4x0.7 threads, so I created an over-long 4mm cylinder passing through the location where I wanted the internal threads. I say over long - so I could see the threads, without turning visibility off for my target part or making a cross-section view.
- Launch the ThreadCreator script and select the cylinder and specify your pitch (0,.7 in my case). Toggle the arrow if necessary to generate external threads on the cylinder. Close/finish the ThreadCreator operation.
- Perform a Boolean subtraction of the threaded cylinder from the target part.
Some of those steps were not obvious to me before a lot of experimentation. I could never get ThreadCreator to create internal threads on the interior surface of a cylindrical hole. The required diameters of the cylinders or the cylindrical holes were not obvious to me (use tap diameter?, outer thread diameter?). And I have not experimented with ANSI threads where the diameters will be much more obtuse.
I understand that having "modeled" threads is computationally complex, but I must say that the way Fusion360 handles the creation of threads is far more intuitive (and built-in). And once you have created the threads, they let you toggle between "modeled" and "visual" threads with a simple checkbox.
Anyway, I would welcome additional advice, and I hope this isn't covered elsewhere (but I couldn't find any instructions on internal threads). THX!
