Now I have just learned to my great surprise that Rhino, which had become my aim to acquire, has no thread modeling capabilities.

You can model a thread in Rhino. You draw a helix of the correct
diameter/pitch then loft the thread shape along the helix path. If you
look on the Rhino site I'm sure there is a tutorial somewhere.

Also there is a plugin at
