Your responses seem to point you at various modules that relate to 3D rotations, but not to how to use them to solve you specific problem.

But perhaps that is because your problem description is not very clear. Eg,

the x, y and z co-ordinates of a point on the line

Which "line"? You haven't mentioned a line before. Do you mean the axis of rotation partially described by the "Axis Unit Vector"?

And why are the coordinates of this point "x, y and z co-ordinates", and not "a 3D Cartesian point" or "the Cartesian co-ordinates of the point" as with the other two points you mention?

I think I understand what you are trying to achieve, but it took many reading of your post to arrive at what is essentially little more than a guess. So I'll describe what I think and see if it fits.

You have

  1. the 3D coordinates of point A.
  2. the unit vector and 3d coords for a point describing an axis of rotation: R
  3. the 3D coordinates of a point B, that is a rotation of A about R.

What you are seeking to find, are the 3D coordinates of point A', as it rotates around R from A to B; in 1 degree steps.
