Space between leader line and the mark is perfect when it’s on the right side. But this gap will be more if we move the mark towards the left. We can adjust this clearance on “Part Mark Properties”. Take “General” window on mark properties and select “Right” in alignment option and modify. Alignment is fixed properly.

This leader line option is available in the following mark types: bolt marks, connection marks, part marks, neighbor part marks, pour object marks, reinforcement marks, neighbor reinforcement marks, merged reinforcement marks and surface treatment marks.
