Hello, I have a series of leaders (arc, line, spline) that we use. The arc one uses a arc and then inserts an arrowhead block to the end of the leader (lastpoint). I like how the autocad qleader unifies the our block with line so that when we grip the line, the angle of the arrowhead stays with it. I prefer to use my routines for leaders, but how can I make it so that my arrowhead block attaches itself to the line or arc and can change angles when I grip the line?
