A frustrating problem when creating custom arrowheads for dimensions and leaders is that when you make the custom arrowheads single lines/curves they display and print with a fixed ‘hairline’ width instead of their defined print thickness.
An obvious workaround is to offset the curves and create hatches that mimic the thickness of the line weight but these will not update when the print thickness of layers/dimensions/leaders are changed.
I assume custom arrowheads simply lack an association to the print thickness of their parent layer/dimension/leader object?
