I measured a line theoretically parallel to the X-axis but not at z=0 plane. I want to align X-axis paralell to this line but won't change the origin. So I used ROTATE XLUS around YPLUS. IT is not right.
When I did the initial alingment, I measured a cylinder, whose center line is Y-axis. So I used ROTAE YPLUS around ZPLUS. It seems right to me. What did I do wrong for the the above case?
