Back in my AutoCAD days and the days of the pen plotters I created this custom arrowhead. The reason for this was it was just one stroke or path for the plotter. Back then the pen would do multiple passes to fill their standard ones. The plotter would vibrate. OK, so we don't have pen plotters any more and I dislike the filled look of the standard arrows or the available standards. If you had many it was distracting, to me anyway.
In AutoCAD all you had to do was create a drawing of the arrowhead to fit the parameters.
I have searched far and wide if it would be possible to create a custom in SW and it appears to be impossible.
Haw about it SW? A truly custom arrowhead?
