When in the Quick Leader command (and this only works for quick leader), you can Right-Click before selecting the first point to bring up a settings window. This controls your default leader settings. Things you can change:

  • End style (Arrowhead)
  • Straight or spline leader lines
  • Number of points (or bends) in the leader line
  • Angle constraints for your lines
  • Text justification for both Left and Right side text
  • What the annotation is (block, text, etc). The annotation is then associated with the leader (how it normally handles text).
