rotate cad model based on space point position?

Hello, I'm having trouble aligning a part that's basically a cylinder with a thread in the center.  Currently I have to take a manual space point and rotate the model manually until the point lines up with the model. 

Is there a better way of obtaining an accurate alignment for a part like this?  Without translating the part in any direction, just rotate it until the point lines up with the model?  I'm attempting to scan the threads with a duramax vast xxt.

With the delta between the actual point and the desired nominal, and the thread pitch, you should be able to calculate the rotational angle to move to advance the thread the desired linear distance.

I would think you could iterate your base alignment to get it there.  I do something similar on twin screw compressor rotors.  There's even a method where you don't have to iterate your entire base alignment and can iterate just the point.  (see attached)

 

Let me know if I'm mis understanding something cause it totally seems possible.
