I set rotation origin as (3, 2, 5) and the rotating axis Parallel to z axis. so, how can i set rotation direction?? It suppose to be (3, 2,7) ???? or just (0,0,1) need your help

If you would use (3,2,7) as axis direction, it would not be aligned with z at all, instead pointing away from it slightly in the positive x and y direction.
